6 Wire Harness: Installation
Install the Wire Harnesses
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.
How to install the tab
washers on non-
embedded terminals
1. Install a tab washer onto the positive terminal of each battery to be
managed.
2. Secure each set of washers in place with a nut.
3. Coat the tab washers and nuts with approved antioxidant grease.
Note
Do not disturb existing battery connections. Place the tab
washers and nuts on top of the bolt thread extensions of the
existing battery connections. You must provide your own
nuts for tab washer installation.
Note
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
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 wires to the terminals
on the batteries, contact APC Customer Support at a number
on the back cover of this manual.
