3.Replace the bolt in the battery, and adjust its torque according to the battery manufacturer’s specifications.

4.Coat the tab washer and nut with approved antioxidant grease.

For Battery 1 and the last battery of String A, you must install additional tab washers to connect the Battery Management System unit power wires (String A wires 34

Note and 35). For each unit on the system, attach one additional tab washer. For example, a four-unit system would require five tab washers stacked on top of each other and offset on the positive terminal of both Battery 1 and the last battery of String A. This would include one tab washer to manage the battery and four tab washers to connect each unit’s power wire.

Note

If you experience problems connecting to the terminals on the batteries, contact APC Customer Support at a number on the back cover of this manual.
