Wiring the AC Bypass Assembly
All models other than the “empty” GSLC are equipped with a maintenance bypass assembly. As
needed, the GSLC can be equipped with a bypass assembly using the GS-IOB-120/240VAC or GS-IOB-
230VAC accessory kit as appropriate. The accessory kit should be installed according to its own
instructions. Once installed, it can be wired by following the steps shown in Figure 37 or Figure 38 .
The operation of the bypass assembly is discussed on page 42. A series of GSLC diagrams with the
bypass wiring (as well as the rest of both the AC and DC systems) are shown beginning on page 48.
These drawings show the utility grid circuit connected to the bypass assembly. This is the method
used during factory installation. However, either the grid or the generator circuit may be used. A
prewired assembly may be changed. Remove the first source from the bypass assembly and then wire
the second according to the instructions. Connect the first source directly to the terminals as shown in
the drawings beginning on page 45.
NOTE
: Only one AC source may be bypassed with this assembly, even if two sources are present.
WARNING: Shock Hazard or Equipment Damage
 Bypassing multiple sources will usually connect the sources to each other, which may
damage one or both sources. It can otherwise result in power being routed to
inappropriate places.
 The internal GSLC bypass assembly cannot be used if multiple inverters are in use.
See page 42.
Figure 37 Maintenance Bypass Wiring (split-phase)
To wire the GS-IOB-120/240VAC
after installation:
1. On the disconnect for the AC
source that will be used during
bypass, install a wire from the
upper pole as shown by
1.
Connect it to the upper pole of
the inverter bypass switch as
shown by
2.
2. From the same disconnect,
install a wire on the lower pole
as shown by
3. Connect it to
the lower pole of the inverter
bypass switch as shown by 4.
3. On the right side of the inverter
bypass switch, install a wire on
the lower pole as shown by
5.
Connect it to the right side of
the lower pole on the output
switch
6. Install a second wire
between the upper poles of
each switch as shown by
7
and
8.
