Bypass Assembly
Bypass switching can be used when the inverter is shut down for maintenance. This topic is discussed
more beginning on page 42. The GSLC can be equipped with the GS-IOB-120/240VAC bypass
assembly. The instructions on this page are for making external connections to the bypass assembly
after installation. (The installation wiring for the GS-IOB-120/240VAC is described on page 41.)
If no bypass assembly is used, connections should be made directly to each TBB from the circuit
breakers for the inverter, AC sources, and loads. These connections are designated in Figure 33.
Wiring diagrams for an assembled 120/240 Vac system are shown beginning on page 45.

Inverter AC Connections (split-phase)
To make the connections to the Radian inverter:
1. Designate the top AC circuit breaker as the
inverter AC output disconnect. Install a wire from
the black AC output TBB (as shown in Figure 33
the disconnect marked by
1
.
2. Install a wire from the red AC output TBB to the
disconnect marked by
2
.
3. Install wires on the left side of the disconnect as
marked by
3
and
4
. Connect these wires to the
appropriate L1 and L2 output terminals on
the Radian inverter.
4. Designate the third AC circuit breaker from the
top as the disconnect for one AC source (
GRID or
GEN). Install a wire from the black source circuit
TBB (as shown in Figure 33) to the disconnect
marked by
5.
5. Install a wire from the red source circuit TBB to
the disconnect marked by
6
.
6. Install wires on the right side of the disconnect
as marked by
7
and
8
. Connect these wires to the
appropriate L1 and L2 input terminals on the
Radian inverter (the terminals labeled either
GRID
or
GEN).
7. If a second AC source is present, repeat steps 4
through 6 using the bottom circuit breaker.
8. Install a wire on the inverter’s
NEU terminal and
connect it to the GSLC’s neutral TBB (as shown in
Figure 33). Only one neutral connection is required.
