5.0 XM2-300HP Maintenance, continued
5.2 Battery Charger Voltage
The advanced three-stage charging features of the XM2-300HP are completely self-
monitoring. During normal power supply operations, the power supply continuously verifies
the operating condition of the battery charger. If, for any reason, the battery charger fails, a
Charger Fail alarm displays on the Smart Display. No operator voltage checks are required.
5.3 Battery Terminals and Connecting Wires
Check each battery terminal and connection. •
Verify hardware is clean and the crimped connectors are tight. Terminal connectors •
should be torqued and re-torqued to the battery manufacturer’s recommended
specifications.
If there is an “in-line” fuse in the battery cable, check the fuse holder and fuse.
•
Verify the terminals are properly protected with an approved battery terminal corrosion •
inhibitor such as NCP-2.
Record date of maintenance in the maintenance log.
•
5.4 Output Voltage
Observe Output voltages using the Smart Display. Record the voltages in the maintenance
log.
5.5 Output Current
With the XM2-300HP in normal operating mode observe the Smart Display Output Current.
The value of output current is dependent on the total amount of load connected to the power
supply. Record the current in the maintenance log.
5.6 Check Output Connections
Inspect the XM2-300HP output connectors to prevent problems that may be caused by
improper connector engagements. A good inspection consists of a careful visual inspection.
5.6.1 Visual Inspection
Unplug and inspect the XM2-300HP output connections, using the Service 1.
Power Supply to safely bypass the XM2-300HP.
Remove the AC and DC power sources from the XM2. 2.
Carefully inspect the separated halves of each connector for signs of abnormal 3.
heating, such as a deformed housing or other damage.
Whenever the battery breaker is turned off, or the batteries are not connected, the XM2-300HP automatically
reports a No Batteries alarm. This is a built in safety feature. The unit does not attempt inverter operations,
either standby or test, during a No Battery alarm.
