5. To check the operation of the IRC, ensure that the UPS system is supplying the
load via the inverter or bypass. If the indicators on the customer’s monitoring
equipment show the appropriate status, then it is operating correctly.
If the IRC is not operating correctly, check the wiring, the fuse on the IRC, and
the plug-in terminal blocks for proper seating. If all connections are secure but
the IRC still does not operate correctly, replace the fuse. If this does not
correct the problem, contact your local field service office for verification that
the IRC is working correctly.
