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-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 42.)

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 48.

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 35) 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 (GRID or

GEN). 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

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 GRID or GEN).

5. If a second AC source is present, repeat

steps 3 and 4.

6. Install a wire on the inverter’s NEU terminal

and connect it to the GSLC’s neutral TBB

(as shown in Figure 35). Only one neutral

connection is required.
