5.3 DC Battery and Ground Cabling

5.3.1 Hardware and Torque Specifications

The DC wiring is attached with 3/8” hardware (1” bolt, washer, spring washer) and 8 are provided

with each AMPS24 system (2 per each of the 4 bolting locations). However, the crimp or lug is not

provided.

The crimp/lug can either be on 1” centers with 3/8” or ½” holes, or 1.75” centers with ½” holes only.

Bus bar tie kits for DC- are included to give the installer the option to make a single battery

connection or two separate battery connections (A/B feeds).

Torque specifications for DC wiring (3/8" bolts that attach the DC lugs at the back of the DC

distribution box) are as follows:

• Imperial: 190 – 240 inch/lbs
• Metric: 21.5 – 27.1 N-m
