If you have a different model battery, contact Liebert Global Services for the required torque value.

To access battery cell terminals, disconnect the inter-tier cable and two shelf retaining screws. Once disconnected, insulate (with protective boot or electrical tape) the cables to prevent accidental shorts. The battery shelf can now be pulled out. Tighten each terminal connection to the retorque value.

When replacing a battery, the terminal connections must be cleaned and tightened. Disconnect and insulate the cables connected to the battery. Secure each battery shelf with retaining screws when maintenance is complete.

Rack-Mounted Batteries

If the UPS system uses a battery other than a factory-supplied Matching Battery Cabinet, perform maintenance on the battery as recommended in the battery manufacturer’s maintenance manual, available on the manufacturer’s Web site.
