Single-Phase Wiring
The GSLC allows multiple terminal bus bars (TBB) for multiple AC connections. Because the Radian
inverter possesses two sets of AC input connections and one set of output connections, three terminal
bus bars are available for hot connections, as well as one neutral bus bar. The hot bus bars have
brown insulators in 230 Vac models. A blue bus bar for neutral connections is also available.
The TBB on the left is generally used for the inverter’s AC output connections. The central TBB is for
utility grid connections and the right TBB is for a generator. The preassembled GSLC models follow
this convention.
Each TBB accepts conductors from 70 mm 2 (1/0 AWG) to 2.5 mm 2 (#14 AWG). See Table 2 on page 23
for required torque values.
If steps are inappropriate for a given system (such as instructions for a generator when none is
present), they can be ignored.

To make external AC connections to the
single-phase GSLC:
1. Connect the hot wire from the AC load
panel to brown TBB
1 (AC Output).
2. Connect the neutral wire from the AC
load panel to neutral TBB
2 .
3. Connect the hot wire from the utility grid
panel (if present) to brown TBB
3 (Grid).
4. Connect the neutral wire from the utility
grid panel (if present) to neutral TBB
2 .
5. Connect the hot wire from the generator
(if present) to brown TBB
4 (Generator).
6. Connect the neutral wire from the
generator (if present) to neutral TB
