Making DC Connections
Grounding the DC System
975-0384-01-02
This section describes how to make DC connections between the inverter/
charger and the batteries. Battery cables must be provided by the installer
(see Table 2-2 on page 2–13). This section also provides procedures for
installing the battery temperature sensor.
The inverter's chassis ground lug is located along the rear edge of the unit
(see Figure 2-8) and is used to connect the chassis of the inverter to the DC
grounding system. The terminal accepts wires from #14 AWG to #2 AWG
2
2
(2.5 mm
to 35 mm
).
System grounding for the DC system, which typically involves bonding
(connecting) the battery negative circuit to ground, is dependent on the system
configuration. In some cases, the battery negative will be bonded to ground in
another device such as a charge controller. If a grounded DC system is desired
or required by code, make sure that the system bonding is done in one location
only and that all conductors and connections comply with applicable codes.
