Installing An Optional Relay Interface Module Ii - Eaton Power Xpert 9395P-900 Series Installation And Operation Manual

11. To check the operation of the RMP II, ensure that the UPS is supplying the load via inverter or bypass. If
the indicators on the RMP II show the appropriate status, then it is operating correctly.
If the communication link between the UPS and the RMP II is not present, the RMP II performs a self-test
(all indicators flash and the horn beeps at one-second intervals). If the self-test occurs, check all harness
connectors and the fuse for proper seating. If all connections are secure but the RMP II continues to
self-test, replace the fuse with the spare included in the hardware kit. If a fuse replacement does not
correct the problem, contact an Eaton service representative for verification that the RMP II is working
correctly.
12. To test the indicator lamps, press and hold the horn silence pushbutton for three seconds. All lamps
should illuminate, and the horn sounds continuously until you release the pushbutton.
