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.
14.
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.
