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 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 26 for more information.
Battery Wiring
Consult the Radian Series Inverter/Charger Installation Manual for appropriate 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 19 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 an illustration of hardware installation order on the positive (+) plate.
Follow the instructions below when connecting battery positive (+) cables to these models:
 GSLC175PV1-120/240
 GSLC175PV1-230
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.
 GSLC175-PV-120/240
 GSLC175-PV-230
 GSLC175-120/240
 GSLC175-230
