Installing Circuit Breakers and GFDI

Figure 22 Circuit Breakers

To mount circuit breakers:

1. It may be necessary to remove the

knockout from the location where the

circuit breaker is to be placed to make

room for the circuit breaker to be installed.

Be sure to remove any debris that may

occur from removing the knockout.

2. Place each circuit breaker behind the

premounted rail. Center the device so

that the raised area around the switch

protrudes through the bracket. It may be

necessary to hold the device in place

by hand.

2. When the circuit breaker is in place, insert

the screws included with each breaker

through the holes in the mounting rail.

3. Tighten the screws until secure, but

do not over-tighten.

NOTES

Although there are no specific designations, the upper end of the mounting rail is generally used

for AC devices (including the maintenance bypass). The lower end is generally used for DC

devices, including the GFDI. The preassembled GSLC models follow this convention.

A PV ground-fault device may be required. The OutBack GFDI is pre-installed on some models.

With other models it can be purchased separately for manual installation. (See page 19.) The

GFDI mounts the same way as other circuit breakers. Once mounted, see page 38 and the GFDI

manual for wiring instructions. (Note that the GFDI usually requires multiple rail slots.)

Some installations may require an AC maintenance bypass. This is referred to as the Input-Output

Bypass or IOB. The bypass comes prewired for a single Radian inverter in some GSLC versions.

It can also be purchased separately. See page 41 and the GS-IOB manual for mounting and

wirin

instructions.
