Chapter 4 Maintenance

Door Interlock

Circumvention

Some of the following sections may require moving the isolation switch handle
to the ON position while the medium voltage door is open. The interlocking
safeguards in the mechanism are designed to prevent the handle from moving
to the ON position while the cabinet door is open.

•

To circumvent this safety feature, use a screwdriver, or other tool, to
depress the door interlock lever in a downward movement.

•

Hold the lever down while moving the handle to the ON (closed) position.

Figure 46 - Door Interlock Lever

ATTENTION:

The door interlock mechanism is designed to prevent

access to the medium voltage cell while the unit is energized. When the

unit is in operation, do not circumvent this interlocking safety feature.

Always disconnect and lock out incoming power (refer to

out Procedure on page 53

) before proceeding with any adjustments

requiring the handle to be moved to the ON (closed) position. Failure to

do so may result in electric shock causing severe burns, injury or death.

Door Interlock Lever

ATTENTION:

Use suitable personal protective equipment (PPE) per

local codes or regulations. Failure to do so may result in severe burns,

injury or death.

ATTENTION:

Always perform the Power Lock-out procedure before

servicing the equipment. Failure to do so may result in severe burns,

injury or death.
