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.
