How to install the tab washers on non- embedded terminals

Before you attach the wire harnesses to the batteries, install a tab washer on the positive terminal of each battery to be managed. How you install the tab washer depends on whether the terminal bolt is embedded in the battery.

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.

2.Secure each set of washers in place with a nut.

3.Coat the tab washers and nuts with approved antioxidant grease.

Note

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