If you must mount the NCE on an uneven surface, be careful not to crack the mounting clips or NCE housing when tightening the screws. Use shims or washers to mount the NCE evenly on the mounting surface. Mount the NCE in areas free of corrosive vapors, and observe the environmental limitations listed in the Technical Specifications section. Allow sufficient space to accommodate cable and wire connections (Figure 1). Do not mount the NCE where the ambient temperature may exceed 50 C (122 F). Do not mount the NCE on surfaces that are prone to vibration or in areas where electromagnetic or radio frequency emissions can interfere with NCE communication. Do not obstruct the NCE housing ventilation holes. Do not mount a power transformer below the NCE. 1
On applications where the NCE is mounted inside a panel or enclosure, follow these additional guidelines: Do not install the NCE in an airtight enclosure. Do not install heat-generating devices in the enclosure with the NCE that may cause the ambient temperature to exceed 50 C (122 F). Mounting the NCE Wall Mount Applications Use the holes in the three mounting clips for wall mount applications. DIN Rail Mount Applications To mount the NCE on a DIN rail: 1. Securely mount a 20 cm (8 in.) or longer section of DIN rail horizontally and centered in the required space. 2. Ensure that the bottom two mounting clips are pulled outward and snapped firmly into the extended position (Figure 2). Figure 2: DIN Rail and Mounting Clip Features on the Back of an NCE To mount the NCE on a wall (or other vertical surface): 1. Ensure that all three mounting clips are inserted into the back of the NCE housing and then pulled outward and snapped firmly into the extended position (Figure 2). 2. Mark the location of the three wall mount holes using the dimensions in Figure 1, or hold the NCE up to the wall as a template and mark the locations. 3. Drill holes in the wall at the locations marked in Step 2 and insert wall anchors (if necessary). Figure 1: NCE Mounting Screw Hole Dimensions and Mounting Area Requirements (mm/in.) 3.

Wiring Power Supply, Network, and Communication Connections See Figure 3 for the location of the NCE s power supply terminal, bus terminals and ports, USB port, Ethernet port, and modem port. Figure 4: Pin Number Assignments for Sensor, SA Bus, and FC Bus Ports on NCE, FEC, IOM, and VMA16 Note: Do not remove the red terminal block keys from the board mounted terminal blocks. Removing the keys can result in a removable terminal plug being plugged into the wrong terminal block, which can cause the NCE to malfunction. 24~ Supply Power Terminal Block The 24~ supply power terminal block is a gray, keyed, removable 3-terminal block located on the top side of all NCE models (Figure 3, Figure 9, and Figure 10). In North America, the NCE requires a Class 2, 24 VAC, 25 VA minimum power supply. Outside North America, use a 24 VAC safety extra-low voltage (SELV) transformer at the appropriate rating. A minimum input voltage of 20 VAC is required for the NCE to operate properly. Note: The maximum power consumption of an NCE25 is 25 VA, but that does not include power for internally sourced binary output (BO) points. Applications that provide power to BO points and configurable output (CO) points configured as BO points can require up to 125 VA of additional power over the 25 VA minimum required for the NCE25. SA Bus Terminal Block The brown, keyed, removable, 4-terminal SA BUS terminal block (Figure 3) is provided on all NCE models. Connect the 4-wire SA Bus cable to the SA BUS terminal block. See the SA Bus Rules section for more information. SA Bus Modular Port The 6-Pin modularsensor/actuator (SA) Bus port is available on all NCE models (Figure 3 and Figure 4). The SA BUS port connects to: a Wireless Commissioning Converter (MS-BTCVT-1) to commission the NCE with the Controller Commissioning Tool a DIS1710 Local Controller Display to provide a display screen on NCE25 models without an integral display screen an NS Series Network Sensor to provide room temperature data to the NCE FC Bus Terminal Block The blue, keyed, removable 4-terminal block FC BUS terminal block (Figure 3) is designed for RS485 serial protocol field buses and is available on NCE models that support N2 Bus or Master-Slave/Token-Passing (MS/TP) FC Bus applications. See for NCE model information. Depending on the NCE25 model: connect the 3-wire N2 Bus to the FC BUS terminal block on NCE models that support N2 Bus applications. See Figure 5 and the N2 Bus Rules section for more information. connect the 3-wire MS/TP FC Bus to the FC BUS terminal block on NCE models that support MS/TP FC Bus applications. See Figure 5 and the MSTP FC Bus Rules section for more information. The SHLD terminal on the FC BUS terminal block can be used as a convenient terminal to connect cable shield drains in daisy-chain bus applications that use shielded cable. FC Bus Modular Port The 6-pin modular Field Controller (FC) BUS port is available only on NCE models that support MS/TP FC Bus applications (Figure 3 and Figure 4). Connect a Wireless Commissioning Converter (MS-BTCVT-1) to the modular FC BUS port to commission the NCE with the Controller Configuration Tool (CCT). LONWORKS Network Terminal Block The blue, keyed, removable, 3-position LON terminal block connects a LONWORKS network trunk to NCE25 models that support a LONWORKS network trunk. The Shield (SHD) on the LON terminal block is soft grounded to the NCE chassis terminal, and you can use it as a convenient terminal to connect cable shield drains in daisy-chain bus applications that use shielded cable. 4
RS232C Serial Port The RS232C serial port provides direct connection using a standard 9-pin female to 9-pin female data terminal equipment (DTE) to DTE null modem cable. Use the RS232C serial port to direct connect to a computer serial port to browse to the NCE or to connect to a VT100 or a computer with a VT100 emulator and perform diagnostic procedures. Refer to the Metasys System Extended Architecture Direct Connection and Dial-Up Connection Application Note (LIT-1201639) for information about direct connections to an NCE. Standard USB Port Use the standard USB port to connect an optional external modem. Refer to the NAE Commissioning Guide (LIT-1201519) for information about connecting and setting up an external modem on an NCE. Ethernet Port The (10 or 100 Mbps) Ethernet connection is an 8-pin RJ-45 network port. Use the Ethernet port to connect the NCE to an IP network. Internal Modem An optional internal modem is available on specified NCE25 models. (See Table 13.) The internal modem port is a 6-pin port labeled MODEM. Insert a phone line cable into this port to use the internal modem. Refer to the NAE Commissioning Guide (LIT-1201519) for information on internal modems. Wiring Rules for Networks and Field Buses All NCE25 Series models are designed to connect to Ethernet IP networks and support a single SA Bus. Depending on the model, an NCE25 also supports either an FC Bus trunk, an N2 Bus trunk, or a LONWORKS network trunk. The rules, guidelines, and wiring considerations for each type of network or field bus application are provided in the following tables. IP Ethernet Network Rules All NCE25 models are designed to connect to properly configured IP Ethernet networks. Refer to the N1 Ethernet/IP Network Technical Bulletin (LIT-6360175) for recommended parts and part numbers. Observe the IP Ethernet network rules in Table 1. Note: The Media Access Control (MAC) address is printed on a label on the NCE housing. MSTP FC Bus Rules The MS/TP FC Bus connects Field Equipment Controllers (FECs), VMA1600s, Input/Output Modules (IOMs), TEC26xx thermostats, and third-party MS/TP controllers to NCE256x models. NCE256x models support an FC Bus trunk with up to 32 MS/TP devices. Observe the rules in Table 2 when designing and installing the connected FC Bus. SA Bus Rules The Sensor/Actuator bus (SAB) connects the Metasys IOMs, NS Series Network Sensors, DIS1710 Local Controller Display, specified variable frequency drives, and Wireless Commissioning Converter (MS-BTCVT-1) to an NCE. Observe the rules in Table 3 when designing and installing the SA Bus for your application. N2 Bus Rules The N2 Bus connects N2 controllers to specified NCE25 models. NCE251x models support a single N2 Bus trunk with up to 32 N2 devices. Observe the rules in Table 4 when designing and installing the connected N2 Bus. LONWORKS Network Guidelines The LON Bus connects up to 32 LONWORKS Network controllers to NCE252x models. Observe the rules in Table 5, Table 6, and Table 7 when designing and installing the LONWORKS Network trunk. For more information on LONWORKS networks, refer to the LONWORKS LN-Series Network Communication and Interface Guide Technical Bulletin (LIT-12011253). Wiring the NCE Important: Do not connect 24 VAC supply power to the NCE before finishing wiring and checking all wiring connections. Short circuits or improperly connected wires may result in permanent damage to the equipment. 5
Important: Use copper conductors only. Make all wiring in accordance with local, national, and regional regulations. The NCE is a low-voltage device (<30 VAC) in North America and an extra low-voltage device in Europe. Do not exceed the NCE electrical ratings. Figure 5: FC Bus Terminal Block Wiring Important: Do not remove the terminal block keys. The terminal block plugs and the terminal sockets are keyed to fit together in the correct configuration only. Important: Prevent any static electric discharge to the NCE. Static electric discharge can damage the NCE and void any warranties. Important: Ensure the network and field bus wiring meets the specifications, rules, and guidelines in the Power Supply, Network, and Communication Connections section in this document. Mount the NCE securely before wiring the NCE. Follow these guidelines when wiring an NCE: Route the supply power wires and communication cables at least 50 mm (2 in.) away from the vent slots on the sides of the NCE housing. Provide slack in the wires and cables. Keep cables routed neatly around the NCE to promote good ventilation, LED visibility, and ease of service. b. For LONWORKS compatible networks, connect the wires from the LON network trunk to the removable 3-terminal plug (Figure 6). Note: You can use the shield (SHLD or SHD) terminal as a convenient terminal for connecting the bus cable shield (if shielded cable is used on the bus). Figure 6: LONWORKS Network Terminal Block and Wiring Connections Wiring Communications Bus and Power Terminals To wire the NCE bus and power terminals: 1. Connect the Ethernet communication cable to the RJ-45, 8-pin Ethernet port shown in Figure 3. 2. Connect the field trunk's network cable to the appropriated port. a. For N2 or MS/TP networks, connect the three bus wires to the removable 4-terminal plugs labeled FC (Figure 5). Note: If the NCE is connected to an N2 Bus or MS/TP Bus, set the NCE's EOL switch to the proper position. See Setting the End-of-Line Switch. 3. If required connect the SA Bus cable to the brown 4-terminal SA Bus port as shown in Figure 7. 6
Figure 7: SA Bus Terminal Block Wiring Wiring Input and Output Terminals NCE25 Series models support up to 33 hard-wired I/O points including: 7 BO points 4 CO points 4 analog output (AO) points 8 binary input (BI) points 10 Universal Input (UI) points See Figure 9, Figure 10, and Table 8 for more information. The I/O points are designed for multiple types of input or output, and most of the points are configured in the CCT software. 4. If required, connect the telephone line to the modem port or connect an external modem to the USB port. 5. Make connections to the RS-232 serial ports (if necessary). 6. Connect the 24 VAC supply power wires from the transformer to the removable 3-terminal plug as shown in Figure 8. The middle terminal is not used. Figure 8: 24 VAC Supply Power Terminal Block Wiring NCE Terminal Functions, Ratings, Requirements, and Wiring Guidelines Input and Output Wiring Guidelines Table 8 provides information and guidelines about the functions, ratings, and requirements for the NCE input and output terminals and references to guidelines for determining proper wire sizes and cable lengths. In addition to the wiring guidelines in Table 8, observe these guidelines when wiring NCE inputs and outputs: Run all low-voltage wiring and cables separate from high-voltage wiring. All input and output cables, regardless of wire size or number of wires, should consist of stranded, insulated, and twisted copper wires. Shielded cable is not required for input or output cables. Shielded cable is recommended for input and output cables that are exposed to high electromagnetic or radio frequency noise. Note: Power supply wire colors may be different on transformers not manufactured by Johnson Controls. Follow the transformer manufacturer s instructions or the project installation drawings. Note: The 24 VAC power should be connected to all network devices so transformer phasing is uniform across the devices. Powering devices with uniform 24 VAC supply power phasing reduces noise, interference, and ground loop problems. The NCE does not require an earth ground connection. Inputs/outputs with cables less than 30 m (100 ft) typically do not require an offset in the software setup. Cable runs over 30 m (100 ft) may require an offset in the input/output software setup. Table 9 defines cable length guidelines for the various wire sizes that may be used for input and output wiring. Maximum Cable Length versus Load Current Use Figure 11 to estimate the maximum cable length relative to the wire size and the load current (in ma) when wiring inputs and outputs. 7
FC and SA Bus and Supply Power Wiring Guidelines Table 10 provides information about the functions, ratings, and requirements for the NCE communication bus and supply power terminals, and guidelines for wire sizes, cable types, and cable lengths when wiring the NCE communication buses and supply power. Table 1: NCE Ethernet Network Rules Category In addition to the guidelines in Table 10, observe these guidelines when wiring the SA/FC Buses and supply power: Run all low-voltage wiring and cables separate from high-voltage wiring. All FC and SA Bus cables, regardless of wire size, should be twisted, insulated, stranded copper wire. Shielded cable is strongly recommended for all FC and SA Bus cables. Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for detailed information regarding wire size and cable length requirements for the FC and SA buses.

Only a daisy-chain topology is allowed (no T or Star topology configurations). Supports up to 32 MS/TP controllers on a single FC Bus segment. FC Bus can be up to 1,520 m (4,987 ft) using 0.6 mm (22 AWG) 3-wire twisted, shielded cable. 1 When using fiber-optic connections: 2,010 m (6,594 ft) between two fiber-optic modems Stranded 0.6 mm (22 AWG) 3-wire twisted, shielded cable is recommended. Stranded 0.6 mm (22 AWG) 4-wire (two twisted-pairs) shielded cable is acceptable. Note: The + and - bus leads should be a twisted pair. On applications using 4-wire (two twisted-pairs) cable, isolate and insulate unused conductor. Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for more information. The EOL switch must be set to On (or an EOL terminator installed) on the two devices located at either end of each bus segment on an FC Bus. The EOL switches must be set to Off (or EOL termination disabled) for all other devices on the bus segment on an FC Bus. See Setting the End-of-Line Switch for information on setting the NCE EOL switch. 1 If third-party devices are connected to the bus, the cable lengths should be reduced (if necessary) to match the third-party vendor recommendations. 9
Table 3: SA Bus Rules Category General Number of Devices Supported on the Bus SAB Cable Length Recommended Bus Cable Type 1 EOL Termination on the SAB Rules/Limits Each bus supervisor supports one SAB. An SAB supports up to 10 devices. Note: Note: The SAB supervisor provides power for the NS network sensors on the bus. Due to power limitations, only 4 of the 10 devices on an SAB can be NS sensors. The SAB on NCE25 models that have an integral Local Controller Display do not support an optional DIS1710 Local Controller Display. SABs do not support repeaters. 365 m (1,198 ft) maximum bus length 152 m (500 ft) maximum between an NS network sensor and the bus supervisor FEC or VAV Modular Assembly (VMA) supplying power to the sensor) using bus cable connected to the SAB screw terminal blocks 30 m (98 ft) maximum length for network sensors using bus cables connected to the 6-pin modular jack (6-Pin SAB port) 366 m (1,198 ft) maximum Bus Length 1.5 m (5 ft) maximum between NCE and DIS1710 Local Controller Display Screw Terminal Connections: 0.6 mm (22 AWG) Stranded 4-wire, 2-Twisted Pairs, Shielded Cable for screw terminals Modular Jack Connections: 6-Pin Modular Connectors with 24 or 26 AWG 6-Wire, 3 Twisted-Pairs Each SAB supervisor has integral (fixed ON) end-of-line (EOL) termination, which typically provides sufficient EOL termination on an SAB. Long SAB runs or persistent communication problems on an SAB may require EOL termination at the last device on the SAB (in addition to the integral EOL termination at the SAB supervisor). All NCE25 models are SAB supervisors. 1 If third-party devices are connected to the bus, the cable lengths should be reduced (if necessary) to match the third-party vendor recommendations. Table 4: N2 Bus Rules Category General Number of N2 Devices Supported Cable Length and Type Cable Bus Termination Rules/Maximums Allowed One N2 trunk supported (on NCE251x models only).

Setup and Adjustments Data Protection Battery The NCE is shipped with the data protection battery installed and connected. Do not disconnect the battery for any reason other than to replace a defective battery. The 24 VAC supply power to the NCE charges the data protection battery. At initial startup, the battery may require a charging period of at least 4 hours before it supports data protection if power fails. Maximum protection (up to 3 consecutive power failures without recharging time) requires a 15-hour charging period. The data protection battery slowly loses charge when 24 VAC power is removed from the NCE. If the battery completely loses charge, the NCE real-time clock stops. Whenever an NCE is disconnected from 24 VAC power for over 30 days, ensure that the real-time clock is set properly and that the NCE is powered long enough to recharge the data protection battery. Powering On the NCE After applying 24 VAC power, the NCE requires approximately 5 minutes to start up and become operational. See the LED Test Sequence at Startup. Startup is complete and the NCE is operational when the green RUN LED is On steady and the red FAULT LED is Off (Figure 14). Important: Wait for the NCE to complete the start-up sequence and the RUN LED to go On steady before initiating any other action on the NCE. Disconnecting Power from the NCE When 24 VAC supply power to an NCE is disconnected or lost, the NCE is nonoperational, but the POWER LED (Figure 14) remains On and the data protection battery continues to power the NCE for several (approximately 1 to 8) minutes while volatile data is backed up in nonvolatile memory. The RUN LED goes Off when data backup and shutdown is complete. Important: The data protection battery must be installed and charged before disconnecting the 24 VAC supply power. Setting the End-of-Line Switch RS485 serial protocol bus segments require proper EOL termination to reduce interference from signal bounce back on the bus segment. 16
FC Bus MS/TP applications require a terminated device at each end of each FC Bus segment. See the MSTP FC Bus Rules section for more information on EOL requirements on an FC Bus. N2 Bus applications are self terminating and have no EOL setting. See the N2 Bus Rules section for more information on EOL requirements on an N2 Bus. The NCE25 models that support MS/TP FC Bus applications or N2 Bus applications have an EOL switch, which must be set according to the position of the NCE on the FC Bus or N2 Bus segment. The NCE25 is shipped with the EOL switch in the factory default, ON (up) position (Figure 12). Figure 12: FC Bus EOL Switch in the Factory Default ON (Up) Position See Figure 13 to determine the appropriate EOL switch setting for the NCE in your field bus application. Figure 13: EOL Switch Setting Relative to NCE Position on the N2 Bus or FC Bus Segment Setting the Network and Device Addresses You must assign a new IP network address to the NCE25, so it can communicate on the IP Ethernet network. The NCE25 MAC address is fixed and is printed on a label on the housing. Refer to the NAE Commissioning Guide (LIT-1201519) for information on assigning an IP address to the NCE25. The NCE25 is always the SA Bus supervisor and, therefore, always has a fixed device address of 0 on the SA Bus. The supervisory controller on NCE25 models that support an (MS/TP) FC Bus is always an FC Bus supervisor and has a fixed device address of 0 on the FC Bus. The field controllers in all the NCE25 models have fixed device addresses of 4 on the NCE FC Bus. Refer to the MS/TP Communications Bus Technical Bulletin (LIT-12011034) for more information on device addresses on (MS/TP) FC Buses and SA Buses. NCE25 models that support an N2 Bus are always bus supervisors on the N2 Bus, and they do not require a user assigned device address to communicate on the N2 Bus. NCE25 models that support a LONWORKS network trunk have a unique LONWORKS address that is factory-assigned as part of the integral LONWORKS Neuron chip on the NCE252x Type models. You do not need to assign a LONWORKS device address to an NCE25 on LONWORKS applications. Binary Output Source Power Selection Jumpers The BO source power selection jumpers determine whether a BO provides internal power (sourced from the NCE) to the output load (INT position) or requires an external power source (EXT position) for the output load. Figure 9 shows an example of the NCE controller BOs and the associated power selection jumpers next to the BO terminal blocks. Position the jumpers next to the BO terminals to provide either internal 24 VAC power to the BO load or act as a switch for an externally powered BO. Each NCE25 BO wired in an application must have the jumpers positioned properly for the application. See Figure 9. Important: Do not connect an external power source to a BO when the BO power source jumper is in the internal power (INT) position. Connecting external power to a BO that sources internal power can damage the controller and void any warranties. Display Screen and Display Navigation Keypad Specified NCE25 models feature an integral display screen and display navigation keypad that allow you to view and edit the I/O points settings on the NCE25 (Figure 3). Refer to the DIS1710 Local Controller Display Technical Bulletin (LIT-12011270) for more information on using the display screen and keypad. 17
Troubleshooting LED Status Indicators The NCE25 models have up to 11 LEDs (depending on model) to indicate power and network communication status. Figure 14 shows the LEDs and Table 11 describes the LED indications. Figure 14: NCE25 LED Designations Refer to the NAE Commissioning Guide (LIT-1201519) for additional information on troubleshooting an NCE. LED Test Sequence at Startup During startup, the NCE automatically initiates an LED test to verify the operational status of the LEDs. Immediately after power is supplied to the NCE, the following LED lighting sequence occurs: 1. The POWER, BATT FAULT, 10 LINK, FAULT, RUN, and PEER COM LEDs turn On, indicating that the operating system (OS), is starting. (After 2 seconds, the LEDs may change states depending on the site-specific network activity.) 2. The BATT FAULT, PEER COM, and FAULT LEDs shut Off. The RUN LED flashes to indicate that the NCE software is loading. 3. The LEDs display the operational status of the NCE. When the RUN LED goes On Steady, startup is complete and the NCE is operational. The total time to start up the NCE depends on the size of the database and can take several minutes.
