DC Wiring
WARNING: Shock Hazard
Use caution when working in the vicinity of the inverter’s battery terminals.
CAUTION: Equipment Damage
Never reverse the polarity of the battery cables. Always ensure correct polarity.
CAUTION: Fire Hazard
 The installer is responsible for providing overcurrent protection. Install a
circuit breaker or overcurrent device on each DC positive (+) conductor to
protect the DC system.
 Never install extra washers or hardware between the mounting surface
and the battery cable lug. The decreased surface area can build up heat.
See the hardware diagrams on page 21.
IMPORTANT:
Table 4 contains OutBack’s recommendations for minimum cable sizes.
Other codes may supersede OutBack’s requirements. Consult local codes
for final size requirements.
Figure 15 GS7048E and GS3548E Battery Terminals
The Radian inverter has four battery cable terminals, two positive
and two negative. Each terminal is a threaded hole which accepts
a hex bolt (provided). Notes on assembly and cabling are shown
on the next page.
IMPORTANT:
 The Radian GS7048E contains two internal power modules, each with its own
set of DC terminals. Both sets of terminals
must be connected to battery
power for the inverter to work correctly.
 The Radian GS3548E contains a single power module which occupies the
space on the left. Although it has two pairs of terminals, only the pair on the
left is functional. The battery cables must be connected to these terminals.
The terminals on the right must not be connected to battery power.
