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