1 NG-0-R -RM -RMS -TM -VM ontrol and monitoring modules for use with the Raychem NG-0 Installation Instructions Description The NG-0-RM/-RMS and NG-0-TM provide ground-fault and line current sensing, alarming, switching and inputs for five heat-tracing circuits when used with the NG-UIT. The NG-0-RM is used to control Electromechanical Relays (EMRs) and the NG-0- RMS is used to control Solid State Relays (s).

2 leaning Instructions If dust accumulates on the NG-0-RM/-RMS circuit board use compressed air to remove the dust. Turn off all power to the NG-0 panel. arefully disconnect all cables from a single NG- 0-RM/-RMS card, making sure to label cables so that they can be reconnected after board cleaning. Wear an anti-static wrist strap connected to ground in order to avoid component damage. Remove the RM/RMS circuit card from the card cage and place on a clean lint-free surface. Use dry compressed air from a can for cleaning circuit boards. (Avoid factory compressed air since it may contain enough moisture or oil to cause permanent damage.) Use short quick blasts to remove dust build-up as necessary. After cleaning, replace the RM/RMS in the same card cage position and reconnect all cables. Remove only one card at a time for cleaning to avoid any problems during re-installation. NG-0-R Installation Instructions Mounting of ard Rack Use the mounting template (on page 7) to mount the rack on a panel backplane. There are four holes (0.88 in dia.) to secure it to the mounting surface using #8 screws. Once the card rack is installed, a earth bonding wire (green 8 AWG min.) terminated with a #0 Ring terminal must be connected to the card rack using the ground screw provided. Note: The card rack must be installed on a non-combustible surface. 7.0 in 0.97 in (8 mm) (79 mm).5 in (8 mm) Grounding screw Note: screw is located on the outside of the enclosure NG-0-RM/-RMS Installation Instructions NG-0-RM/RMS MSB LSB TB TB TB TB TB 5 TB 9 TB TB 7 TB 6 TB TB TB 5 TB 6 TB 7 Alarm output Relay outputs (5x) LEDs (9x) Fuse Vdc Inputs (x) End of Line (EOL) jumper RS-85 ommunications Line & ground-fault sensor inputs (5x) Inputs Address Switches Power Relay Relay Tx Alarm Relay Relay Rx Relay 5 LED functions 7.00 in (78 mm) 0.75 in (7 mm) Industrial Heat Tracing SOLUTIONS EN-RaychemNG0R-IM-H577 0/5 / 8

3 Power Supply The power supply connector (TB9) is a dual two pin connector. Either connector allows for power in (pin # (+), pin # ( ) and bussing of power to other NG-0-RM modules). Note: Power supply must be sized correctly based on the number of NG-0-RM/- RMS modules. RS-85 ommunications The RS-85 connector (TB6) is a dual three pin connector. Either connector allows for RS-85 input signals (pin # (shield), pin # (+), pin # ( )) and bussing of RS85 signal to other NG-0-RM modules. End of Line (EOL) Jumper If this device (NG-0-RM/-RMS) is the last device in the RS-85 network, the J jumper needs to be moved from terminals & to terminals &. Inputs Ordinary Area wire s with shield may be connected to h thru h 5 (TB - TB5). The two common wires (usually red, red) are connected to terminals &, the source (usually white) to terminal and the braid to terminal (earth ground). Note: 's are not required if monitoring per each NG-0-RM board current/ground-faults only or if 's are connected via RMMs. connected directly to RM board Inputs Hazardous Area For all terminations in a hazardous area, the field wires must be terminated on a panel-mounted terminal block. hassis Ground NG-0-RM/RMS Board 5 Terminal block Factory wired Normal position End of Line position RM PB Hazardous area Relay Output onnections to ontactors or Solid State Devices (TB7) This connector switches voltage to the contactor coils or solid state relays. The pilot relay will switch the supply voltage (up to 77 Vac) to the contactor coil (using an NG-0-RM) or Vdc to the solid state device (using an NG-0-RMS). Refer to system layout diagram for detail wiring. ommon Alarm The common alarm terminal block (TB) provides a form dry contact, rated at 77 Vac max (A). When the Raychem NG-0 system is powered on, the common alarm relay coil is energized and pin is connected to pin (common). This is the "No Alarm" condition for the RM/RMS board. 0-RLY 8-RLY -RLY OM 6-RLY5 -RLY OM losed Open If the alarm occurs, or the RM/RMS board loses power, the relay coil is de-energized and pin (common) is disconnected from pin and connected to pin to indicate an alarm condition exits. Address Switches (SW & SW) Each NG-0-RM/-RMS must have a unique communication address selected. The valid address switch range when using the NG-UIT is -99. SW is the ones digit (0 9) and SW is the tens digit (0 or 9). Note: When adding an NG-0-RM/- RMS to the system, you must first cycle power on the RM/RMS board and then perform a network update at the NG-UIT. Optional Voltage Sensor able Preparation Notes:. ut one end off of a groundfault /line current cable.. Strip insulation approx. inch from cut end..

Trim brown and orange wires from cut end. Optional Voltage Sensor The optional voltage sensor can monitor Vac. This voltage connects to one of the five line current/ground-fault inputs on the NG-0-RM. Note: By using the optional voltage sensor, you lose the ability to monitor the ground-fault and current for that circuit.

NG-0 Installation Test Procedures Once assembled into a panel, the Raychem NG-0 components must be tested as a system to ensure that the ground fault detection circuitry is functional. The following tests must be conducted by qualified personnel familiar with the equipment and its operation, test procedures, and electrical code requirements. Make as many copies of this checklist as required to document successful tests for each circuit in the panel. Abbreviations: GF = Ground Fault T = urrent Transformer NG-0-RM/-RMS Board: Tested By: Date: ircuit # ircuit # ircuit # ircuit # ircuit #5 Inspect the wiring to ensure that all load conductors pass through the GF T. Verify that no ground (PE) conductors pass through the GF T. Ensure that conductors on the load side of the GF T are not grounded. Simulate a GF on the load side of the GF T large enough to cause the NG-0-RM or NG-0-RMS to trip its output off. This should occur within approx. second of applying the test GF current. ompleted forms should be retained with the panel and available for inspection by the local Electrical Inspection Authority.
