Install the Wire Harnesses
8 Wire Harness: Installation
Prepare the harness
wires
To prepare the harness wires:
1. Measure the length of each wire so that it will reach from the
positive terminal on its battery to the battery connector on the rear
of the Battery Management System, adding a ‘service loop’ that
will permit one repair of the wire without having to replace it.
2. For an APC Silcon unit, measure wires to connect to the fuse bus
and midpoint bus located on the inside roof of the battery cabinet.
3. Cut the wires to the lengths measured in step 1 and step 2, and
reattach the wire labels to the wire ends.
4. For an APC Silcon unit, attach the male Faston connectors to the
fuse bus and midpoint bus wire ends, and crimp them securely in
place.
5. Attach the female Faston connectors to the battery wire ends, and
crimp them securely in place.
Install the battery and
power fuses
Attach a 5 A fuse (0W2015) to the following wire connectors:
• Strings A–33A
• Strings 1B–33B, if applicable
• String 35A (negative power wire)
Attach a 3/4 A fuse (0W2237) to String 34A (positive power wire).
See “Determine fuse bus and midpoint bus connections
(Silcon only)” on page 4.
