4.0 Maintenance, Continued
4. Inspect Inverter Module
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:
Operational Data:
Output 1 Voltage
Output 2 Voltage (if AlphaDOC installed)
Output 1 Current
Output 2 Current (if AlphaDOC installed)
Input Voltage
Standby Events
Total Standby Time

Always switch the battery breaker OFF before removing or installing the Inverter Module assembly.
CAUTION!
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.
NOTICE
:
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.
