This section describes the DC wiring requirements and how to make the
connections. It provides the required cable and wire sizes, recommended lengths
for cables, and disconnect/circuit breaker requirements. All wiring should be
made with minimum 90° C wire. The ground lug on the DC end of the Trace
Series is 5/16 in. (7.87 mm).

Grounding is an important part of the system installation and must be performed
correctly to ensure safe operation of the equipment. Grounding requirements vary
by country and application. Consult your local electrical codes for specific
requirements.
This product is intended to be installed as part of a permanently grounded
electrical system. This is the single point earth ground for the inverter system.
To ground the DC circuits:
1. Connect the negative (-) terminal of the battery bank to an appropriately sized
conductor and connect it to the ground bus in the DC Disconnect.
2. Connect an appropriately sized conductor to the Ground bus in the DC
Disconnect and connect it to the primary system ground.
3. Torque ground nut to 10-15 in-lb (1.1 - 1.7 Nm).
The system ground is the same ground used by the AC side of the system.

The ground conductor should be sized appropriately for the over-current
protection device being used. See Table 2-1 and Table 2-2 below for a portion of
the NEC and CEC codes). For installations in countries other than the USA and
Canada, different local codes and cable sizes may apply.
