Operating Instructions

Manipulating the Moveable Drawout Element

Racking Pump Handle

A low-force pump handle is used to rack the moveable

drawout element. The pump handle is an integral part of the

racking mechanism, eliminating the need for an auxiliary rack-

ing device. If there is any resistance in returning the pump

handle to the stowed position, set the directional shift lever to

the neutral position. The racking pump handle can then be

returned to the stowed position.

Drawout Position Indicator

A color-coded indicator displays the position of the moveable

drawout element: connected (red), test (yellow), and unlocked

(yellow). When the moveable drawout element is being racked

from one position to another position, the indicator will display

the more critical position.

The Connected position is deﬁned to be more critical than the

Test position and the Test position to be more critical than the

Unlocked position. This means that when racking the move-

able drawout element from the Connected position to the Test

position, the indicator will continue to display the Connected

position until the moveable drawout element has been racked

all the way to the Test position. Conversely, when racking from

the Test to the Connected position, the indicator will display

the Connected position as soon as the SB breaker is moved

toward the Connected position. The process is the same when

racking between the Test and Unlocked position.
