5.7 Inverter Module Maintenance
Carefully remove the inverter module assembly (see Section 2.3, Inverter Module 1.
Removal and Installation).
Inspect the inverter module for signs of dust or corrosion. 2.
Inspect ventilation holes to verify they are clear of obstruction from debris or other 3.
equipment.
4. Reinstall the inverter module (see Section 2.3 Inverter Module Removal and Installation)
and test the XM2-300HP for proper operation (see Section 4.1, Start-up and Test).
5. If the XM2-300HP passes all previous tests (e.g. Battery Load Test, Self Test):
Turn off the utility input breaker to remove input power. The XM2-300HP will go into •
standby operation.
Verify there is no interruption to the output. •
Observe the battery voltage reported on the Smart Display. If battery voltage drops •
below 11.5Vdc, reapply utility power immediately. After five minutes reapply utility
power. The power supply then transfers back to Operation Normal, clears any alarms
and starts the battery charger (BULK mode, if needed). This test adds standby events
and time to the event counter.
Circuit boards are static-sensitive and must be handled with care.
CAUTION!
If the XM2-300HP fails the following test, there will be a loss of power to the load without the use of
a Service Power Supply. Do not perform the next test step if the power supply or battery is suspect,
or the load is at a critical stage.
CAUTION!
