4. Racking mechanism insertion port
The shutters are closed when the Arc Vault is in the
DISCONNECT Position. As the Arc Vault is racked from the
DISCONNECT Position to the TEST Position the shutters
remain fully closed. As the device is racked from the TEST
Position to the CONNECTED Position, the shutters open
allowing the device to connect to the primary disconnects.
The cassette racking arm slots engage fixed racking
anchor pins on the sides of the Arc Vault. As the racking
arms are rotated by operation of the racking crank, the Arc
Vault is pulled into the compartment, and locked in its final
connected position.
Note that extra items shown in Figure 3-6, (such as
secondary disconnects and shutters) are optional and may
appear in any compartment or not be included at all,
depending on the equipment specified.
