Bypass Assembly

Bypass switching can be used when the inverter is shut down for maintenance. This topic is

discussed more beginning on page 47. The GSLC can be equipped with the GS-IOB-230VAC

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-230VAC is described

on page 47.)

If the GSLC has no bypass assembly, 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 35.

Wiring diagrams for an assembled 230 Vac system are shown beginning on page 54.

Figure 36 Inverter AC Connections (single-phase)

To make the connections to the

Radian inverter:

1. Designate the topmost AC circuit breaker

as the inverter AC output disconnect.

Install a wire from the AC output circuit

TBB (as shown in Figure 36) to that

disconnect as marked by 1.

2. Install a wire on the left side of the

disconnect as marked by 2. Connect the

wire to the appropriate output terminals

on the Radian inverter.

3. Designate the third AC circuit breaker as

the disconnect for one AC source (G

RID

or G

EN). Install a wire from the TBB of

the appropriate source circuit (as shown

in Figure 35) to the left side of that

disconnect as marked by 3.

4. Install a wire on the right side of the

source disconnect as marked by 4.

Connect the wire to the appropriate input

terminal on the Radian inverter (the

terminal labeled either G

RID or GEN).

5. If a second AC source is present, repeat

steps 3 and 4.

6. Install a wire on the inverter’s N

terminal and c

onnect it to the GSLC’s

neutral TBB (as shown in Figure 36).

Only one neutral connection is required.
