Contact an Eaton service representative to schedule a date.13. To check the operation of the RMP II, ensure that the UPS is supplying the loadvia inverter or bypass. If the indicators on the RMP II show the appropriatestatus, then it is operating correctly.If the communication link between the UPS and the RMP II is not present, theRMP II performs a self‐test (all indicators flash and the horn beeps at one‐secondintervals). If the self-test occurs, check all harness connectors and the fuse forproper 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 fusereplacement does not correct the problem, contact an Eaton servicerepresentative for verification that the RMP II is working correctly.14.
