Replacing the battery
The battery is rated for a service life of up to five years, which varies depending on
operational and environmental conditions. The battery life expectancy depends on the
operating environment as temperature extremes shorten the battery life.
The battery is specifically designed to use with the iNID system. Refer to the label
inside the front cover of the iPSU or contact your service provider for battery
replacement information.
To replace the battery:
1. Use a Phillips screwdriver to unfasten two screws (one on each side) securing the
power supply battery cover, and put them in a safe place.
2. Adjust the battery cable and battery cable connector so that it is visible (located on
top of the backup battery).
3. Press down on the tension springs and pull to disconnect the battery cable
connector from the battery cable.
4. Release the safety strap securing the battery.
Remove screws from both sides
of the unit to remove the front
cover.
