Input Disconnect Switch

Electrically located on the input power side of the Bypass unit, the disconnect provides a through the door padlockable operator
mechanism. The Bypass three phase input power connection is made to the input terminals of the disconnect. The door mounted
rotary operating mechanism is a convenient means of disconnecting the Bypass unit from line power for equipment maintenance.
The disconnect must be in the OFF position in order to open the enclosure door. The rotary handle can be padlocked in the OFF
position.

This disconnect switch DOES NOT provide branch short circuit protection. A device to provide branch short circuit protection
MUST be provided by others upstream of the E7L Bypass unit.
