5.To check the operation of the RMP, ensure that the UPS is supplying the load via inverter or bypass. If the indicators on the RMP show the appropriate status, then it is operating correctly.

If the communications link between the UPS and the RMP is not present, the RMP will self-test (all indicators flash and the horn beeps at one-second intervals). If this occurs, check all harness connectors and the fuse for proper seating. If all connections are secure but the RMP continues to self-test, replace the fuse with the spare included in the hardware kit. If this does not correct the problem, contact your local field service office for verification that the RMP is working correctly.

6.To test the indicator lamps, press the horn silence button and hold it for

3 seconds. All lamps should light, and the horn will sound continuously until you release the button.

7.Repeat steps 1, 2, and 4 through 6 for each RMP you are installing.

8.If you are installing an RIM or SCM in addition to an RMP, proceed to Chapter 5 or 6, respectively; otherwise, secure the UPS cabinet by reversing the steps contained in procedure “To Prepare the UPS for Wiring to an RMP, RIM, SCM, or Remote EPO” of Chapter 2.
