DC Wiring
WARNING: Shock Hazard
Ensure all circuit breakers or disconnect devices are turned off or disconnected
before connecting any wires.
CAUTION: Fire Hazard
Never install extra washers or hardware between the mounting surface and the
battery cable lug. When installing multiple ring terminals or lugs, stack them on the
mounting surface so that the largest conductor is in direct contact. Smaller ring
terminals should be placed next in decreasing size order. Stacking the hardware in
any other order can result in a loss of contact area for current flow. This may allow
dangerous levels of heat to build up.
Inverter Wiring
The DC disconnects are connected directly to the inverter using bus bars during the process of
mounting. See page 29 for more information.
Battery Wiring
Consult the inverter
Installation Manual
for recommendations for cable number, sizing, and
length. When using these recommendations, some models only require one set of battery
cables while other models require two sets of cables. (A single set of larger conductors can be
used if sized correctly.) See Table 1 on page 22 for required torque values.
Ensure DC disconnects are turned to the OFF position and
all
DC sources are disconnected
(unbolt the battery end of the wires) before proceeding.
See the inverter’s installation manual for additional information on battery wiring.
Battery Positive (+) Cable
Follow the instructions below when connecting battery positive (+) cables to these models:
Connect the positive (+) cables to the DC positive (+) wiring plate. This plate is located
directly beneath the main inverter disconnects. It is intended for several ring lugs to be
bolted to it.
 The smaller holes have a diameter of 0.31" (8 mm).
 The larger holes have a diameter of 0.4" (10 mm).
See item
B
in Figure 28 for hardware installation order on the positive (+) plate.
Follow the instructions below when connecting battery positive (+) cables to these models:
Connect the positive (+) cable directly to the DC disconnect, which uses an M8 stud. See
item
A
in Figure 28 for an illustration of hardware installation order on the DC disconnect.
Follow the appropriate instructions when connecting to an “empty” GSLC which has been
assembled with similar features to one of the models above.
