Installation procedure
VR reserving stationary contact removal and
installation
1. Each QD5 tap-changer has one VR reversing stationary
contact. Note that in the photo, the nylon separating
bar has been removed. It is not necessary to remove
the bar to perform these steps. See Figure 96.
2. If the reversing movable contacts are located on the
VR reversing stationary contact, place a 3/8" socket
onto the rear shaft of the motor. See Figure 97. Using
a ratchet, rotate the motor shaft 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.
