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.

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

Connect it to the upper pole of

the inverter bypass switch as

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

Connect it to the right side of
