WARNING
Terminals behind the rear device barrier may be
electrically hot if door is open. Maintenance should
not be performed on the Arc Vault device when
primary conductors are electrically live. Personal
injury may result.
Arc Vault Key Interlock
An Arc Vault key interlock is available to provide protection
against unauthorized operation. See Figure 7-4. The key
interlock is mounted on the right of escutcheon of the
cassette below the breaker.
The typical interlock system is designed so that the key
may be removed from the lock only when the device is
discharged. The key actuates a cam that elevates the trip
bar on the cassette and the device is rendered trip free.
Key Interlock Operation Check
The operation of the key interlock should be checked as
follows:
1. With the device in the CONNECT position, manually
discharge the device. This then allows the key interlock
to elevate the trip bar.When the trip bar is elevated, the
device cannot be charged but the key can be removed.
The device will remain trip free until the key is returned
and the trip bar is lowered.
Top of Arc Vault stack is equipped with an Exhaust
Port swinging door located mid depth. Make sure
this is in the closed position to avoid debris from
entering.
