Installation procedure
VL reversing stationary contact removal and
installation
1. Each QD5 tap-changer has one VL reversing stationary
contact. See Figure 87.
2. If the reversing movable contacts are setting on the
VL reversing stationary contact, place a 3/8" socket
onto the rear shaft of the motor. See Figure 88. Using
a ratchet, rotate the motor shaft counter-clockwise
to move the reversing movable contacts off of the
reversing stationary contact. It may be necessary to
rotate the tap changer through several positions before
the movable reversing contact will begin to move.
