AC Bypass Switch Assembly
The AC bypass switch assembly in the ACCB-L-L1 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 AC bypass switch allows the generator or grid to provide power to the
inverter loads in the event that the inverter is disabled for battery maintenance or
removed for service.
A second AC bypass switch assembly (ACCB-L2-PCK) is available for dual-
inverter installations (ACCB-L-L2 configuration)
.
This field-installed, add-on
package includes pre-cut wires for wiring a second inverter in the lower position
and provides an additional Isolated Hot Bar for optional installation.
For more information see Chapter 3, “Operation” in this guide.

CAUTION: Equipment Damage
Although it is possible to use the second AC Bypass Switch for a second AC input
(i.e., generator and grid) to the same inverter, using the AC Bypass Switch for this
purpose is not recommended. Switching ON both Bypass switches can cause the two AC
sources to short each other out.
WARNING: Electrical Hazard
If the inverter is removed from service while the bypass is used, live circuits inside the
Long AC Conduit Box will not be guarded from accidental contact. Be sure to install the
Blockoff Plates to prevent accidental electrocution if the inverter is removed from the
system.
