5.2 Battery Charger Voltage
The advanced three-stage charging features of the Intelligent CableUPS 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 the 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 power supply 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 output connectors to prevent problems that may be caused by improper
connector engagements.
5.6.1 Visual Inspection
1. Unplug and inspect the output connections, using the Service Power Supply to
safely bypass the power supply.
2. Remove the AC and DC power sources from the power supply.
3. Carefully inspect the separated halves of each connector for signs of abnormal
heating, such as a deformed housing or other damage.
4. If necessary, replace the PDB and SPI harness connector.
Whenever the battery breaker is turned off or the batteries are not connected, the CableUPS
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.
