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:
The DC terminals must be encased in an enclosure to meet NEC requirements.
The GS Load Center (GSLC) meets this requirement.
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 GS8048A and GS4048A Battery Terminals
IMPORTANT:
The Radian GS8048A 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 GS4048A 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.
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.
