4. Inspect Inverter Module
Whenever the battery breaker is turned off or the batteries are not connected, the CableUPS
automatically reports a No Battery alarm. This is a built in safety feature. The unit does not attempt
inverter operations, either standby or test, during a No Battery alarm.
NOTE:
ALWAYS switch the battery breaker off before removing or installing the Inverter Module
assembly.
CAUTION!
You can remove the Inverter Module assembly while the Power Supply is running on line power. The
Power Supply will continue to operate as a non-standby regulated Power Supply
NOTE:
a. Carefully remove the Inverter Module assembly.
1. Shut off battery circuit breaker and disconnect the 36V battery cable
from the Inverter Module.
2. Disconnect the LRI and Temp Probe cables from the Inverter Module
and the TMPR and XPDR cables from the communication module.
3. Loosen the thumbscrews.
4. Grasp tab at base of Communications Module sheet metal and pull
Inverter Module from the Power Supply.
b. Verify Output voltage remains with volt meter.
c. Inspect the Inverter Module for signs of dust or corrosion.
d. Reinstall the Inverter Module (reverse removal procedure) and test the
Power Supply for proper operation.
1. Turn off the utility input breaker to remove input power. The Power
Supply goes into standby operation.
2. Verify on the Smart Display that there is no interruption to the output.
3. After five minutes reapply utility power. The Power Supply then transfers
back to Operation Normal, clears any alarms and starts the battery
charger (BULK, if needed.) This test adds standby events and time to
the event counter.
5. Record the following data from the XM3 Smart Display and record in the XM3
system maintenance log:
