leaning Instructions If dust accumulates on the AS-RM circuit board use compressed air to remove the dust. Turn off all power to the AS-0 panel. arefully disconnect all cables from a single AS-RM 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 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 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. Mounting the AS-RM Directly to the Panel's Back Pan The AS-RM is intended to be installed on the backpan of the AS-PM-5 power control panel. Use the attached template (see page 7) to locate the 6 mounting holes on the panel s back pan. Using a #6 drill bit, drill the six holes and using a #6- tap, tape the 6 holes. Install a #6 nylon standoff ( in. long) between the panel s back pan and RM board and secure with the #6- screw ( / in. long). Optional ard Rack Installation Instructions Mounting of ard Rack Use the mounting template shown in the NG-0-RM Installation Instructions (H577) to mount the rack on a panel backplane. There are four holes (0.88 in. diameter) 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 noncombustible surface..5" (8 mm) 0.97" (79 mm) 7.0" (8 mm) Grounding screw Note: Screw is located on the outside of the enclosure AS-RM Installation Instructions AS-RM 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.

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 AS-RM modules). Note: Power supply must be sized correctly based on the number of AS-RM 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 AS- RM modules. End of Line (EOL) Jumper If this device (AS-RM) 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 AS-RM board current/ground-faults only or if 's are connected via RMMs. connected directly to RM board Normal position End of Line position ommon Alarm The common alarm terminal block (TB) provides a form dry contact, rated at 77 Vac max (A). When the Raychem AS-PM-5 panel 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 board. OM losed Open If the alarm occurs, or the RM 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 AS-RM must have a unique communication address selected. The valid address switch range when using the AS- UIT is -99. SW is the ones digit (0 9) and SW is the tens digit (0 or 9). Relay "No Alarm" ondition Note: When adding an AS-RM to the system, you must first cycle power on the RM board and then perform a network update at the AS-UIT.

AS-0 Installation Test Procedures Once assembled into a panel, the Raychem AS-PM-5 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 AS-RM Board: Tested By: Date: 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 AS- RM or AS-RMS to trip its output off. This should occur within approx. second of applying the test GF current. ircuit # ircuit # ircuit # ircuit # ircuit #5 ompleted forms should be retained with the panel and available for inspection by the local Electrical Inspection Authority.
