The VCB must be open and in the DISCONNECTED/ TEST position
before proceeding.
1. Check that the position indicator flag in lower right front
corner of compartment shows DISCONNECTED/TEST.
2. Ensure that the spring energy is discharged. Check that
indicators on the VCB front cover show DISCHARGED
and OPEN.
3. Disconnect secondary control power plug.
4. Position the lift truck in front of the switchgear
compartment, and rotate the lift truck crank handle to
adjust the height of the lifting platform such that the ends
of the lift arms align with the guide slots just below the
VCB rails in the switchgear compartment. (Turn clockwise

racking access hole located at the bottom of the door,
Figure 5-26 and Figure 5-27, until the racking socket is
engaged with the racking drive screw.
4. Turn the handle clockwise (approximately 20 turns) until
it cannot be rotated any further.
