ARC VAULT EQUIPMENT ACCESSORIES

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.
