WARNING
DO NOT USE ANY TOOL OTHER THAN THE RACKING-IN CRANK PROVIDED
TO RACK THE VSR FROM TEST OR CONNECTED POSITIONS. CORRECT
OPERATION OF SOME OF THE INTERLOCKS IS DEPENDENT ON USE OF THE
PROVIDED RACKING CRANK. PERSONAL INJURY OR EQUIPMENT DAMAGE
COULD RESULT FROM THE USE A TOOL OTHER THAN THE PROPER
RACKING-IN CRANK.
NOTICE
THE VSR AND INTEGRAL RACKING MECHANISM INCLUDES ALL
NECESSARY INTERLOCKS THAT WHEN INTER-FACED WITH A COMPATIBLE
STRUCTURE WILL RENDER THE VSR MECHANISM MECHANICALLY AND
ELECTRICALLY TRIP-FREE DURING THE RACKING PROCESS.
To move the VCPW-VSR to the CONNECTED position, engage the
racking-in crank with the structure mounted racking shaft (Figure
5.9). Turn the racking-in crank in a clockwise direction and the VSR
will move slowly toward the rear of the structure. When the VSR
reaches the CONNECTED position, it will become impossible to
continue turning the racking-in crank. The CONNECTED position
will also be indicated by a red flag indicator just below the racking
device. If a spin-free racking-in crank is being used, it will spin free
once the CONNECTED position is reached. Secondary contacts will
automatically engage if not already engaged manually in the TEST
position.
To remove the VCPW-VSR from the structure, reverse the procedure
just described by turning the racking-in crank in a counterclockwise
direction. Keep in mind that safety interlocks may cause the VSR to
open during the removal process. It depends on what condition the
VSR was in as removal began.
