When installing DC cables:
Make certain DC circuit breakers are turned to the off position, or fuses are removed, before proceeding.

 Battery positive (+) and negative (–) cables should not exceed 10 feet (3 m) each to reduce voltage loss and other effects.
The modular construction of the GS8048A requires the use of two DC circuit breakers or fuses.

The cables for each overcurrent device must each be sized appropriately. Alternately, a single cable or bus may be used

if sized to the minimum total ampacity. The cables listed above are for each inverter in a system. In a multiple-inverter
system, each inverter requires its own cables and overcurrent devices of the size indicated.
Install all overcurrent devices on the positive cable.

Tie, tape, or twist positive and negative cables together to reduce self–inductance. Run positive and negative cables

through the same knockouts and conduit.
NOTE
: Do not install hardware in a different order from the illustrations shown in Error! Reference source not found.. In
all cases the battery cable lug must be the first item installed. It must make solid contact with the surface.
If the battery cables are connected directly to the Radian

inverter, the hardware should be arranged as shown in image A.
The inverter's battery terminal is a threaded hole which accepts
a hex bolt (provided). The battery cable lug must have a
0.79 cm (5/16") diameter hole.
 If the inverter is installed with the GS Load Center (GSLC),
follow GSLC instructions for cable and hardware installation.
The hardware should be arranged according to the appropriate image below.
GSLC models used with the GS8048A inverter are equipped with a DC positive (+) plate. The plate accepts an M8 hex

bolt and nut. See image B.
GSLC models used with the GS4048A inverter do not use the DC positive plate. The cable lugs are connected to the

DC disconnect, which uses a threaded M8 stud. See image C.
All GSLC models connect the battery negative cables to the shunt, which is threaded for 3/8" bolts. See image D.
