Manipulating the Moveable Drawout Element

CAUTION

Test Position to Unlocked Position

Racking the moveable drawout element from the Test position to

the Unlocked position disengages the moveable drawout

element from the stationary drawout element. The physical

position of the moveable drawout element will be unchanged. To

rack the moveable drawout element from the Test position to

Unlocked position, complete the following steps:

1. Pull out the directional shift lever. This is the racking-out position.

2. Pull the release lever down to the interlock disengaged position.

(Illustrated beneath the padlock device.) If the breaker contacts are

closed, this action will trip the breaker.

3. If breaker will be withdrawn: Extend side rails fully until they are in

a horizontal position (3200-5000 amp only).

4. Pump the racking pump handle until the moveable drawout element

is in the Unlocked position.

5. When the moveable drawout element reaches the Unlocked posi-

tion, the release lever will automatically return to the interlock en-

gaged (up) position and the position indicator will display the

Unlocked position. Pull out the extension rails until they hit a solid

stop before pulling out the moveable drawout. (3200-5000A only).
