Installation

Bypass Switch Assembly

The bypass switch assembly in the ACCB is designed for 120 Vac applications and comes with two 60-amp circuit breakers (one SPST and one DPST). The breaker pair is equipped with a lockout rocker that allows only one breaker to be ON at any given time.

The bypass switch allows the generator or grid to provide power to the inverter loads in the event that the inverter is disabled or removed for service.

For more information see Chapter 2, “Operating the ACCB”, in this guide.

WARNING: Electrical Hazard

If the inverter is removed from service while the bypass is used, live circuits inside the ACCB will not be guarded from accidental touch. Be sure to install the Safety Plate (SP-1) to prevent accidental electrocution if the inverter is removed from the system.

Safety Plate (SP-1)

A Safety Plate (SP-1) is provided to enclose the ACCB to prevent accidental contact with any AC power within the ACCB if the inverter is ever removed from the system configuration. The safety plate is not used in the initial installation and should be stored in a convenient location.

See page 1–40for installation instructions for the Safety Plate.
