(h) Install shims as necessary between the pole-unit
base and the support brace to compensate for any
irregularities between the mating surfaces.
Repeat for the pole-units—marked “Pole 1” and “Pole 3.”
Connecting the Pole-Units to the High-Speed Power
Train
STEP 13.Prepare the insulated operating rod of each pole-
unit for attachment to the interphase drive in the
high-speed base as follows:
(a) Remove the six 5/16 -18 ×¾-inch hex-head stainless
steel cap screws used to attach the access cover to
the side of the transition box. See Figure 11. Remove
the cover and place it and the hardware on a clean
surface.
(b) Check that the transition lever is in the open
position. The lever should be turned fully
counterclockwise. See Figures 11 and 12. If the
lever is not in the Open position, carefully turn the
transition lever to the Open position.
If the transition lever cannot be freely rotated to
its fully counterclockwise position, misalignment of
the interphase drive is occurring in the high-speed
base. Swing the insulated operating rod end links
up, away from the interphase drive linkage lever,
and try rotating the transition lever to its fully
counterclockwise position.

CAUTION
Keep fingers clear of the transition lever’s travel.
The transition lever is under pressure and could quickly
rotate counterclockwise. Injury to the fingers could
result.
(c) Remove the ⅜ -inch stainless steel connecting pin
used to attach the transition lever to the operating
rod link. See Figure 12 on page 17. The pin is locked
in place by a retainer. Lift and turn the retainer to
remove the pin. Keep the pin for re-use in Step 13(e)
(d) Attach the insulated operating rod end links to the
interphase drive linkage lever in the high-speed
base using the ½-inch silicon-bronze pin and cotter
pin retained from Step 12(d). See Figure 13 on page
17. The insulated operating rod may be moved up or
down, as required, to make the connection.
(e) Replace the ⅜ -inch stainless-steel connecting pin
retained from Step 13(c). See Figure 12. It will be
necessary to loosen the 5/16 -18 × 2-¼ -inch hex-head
stainless-steel screw, holding the spacer in place,
and withdraw it approximately ⅛ -inch, so the
connecting pin can be inserted. Do not remove the
screw at this time.
(f) After the connecting pin has been inserted, lock it in
place with its retainer.
(g) Remove and discard the 5/16-18 x 2-¼ -inch hex-head
stainless-steel screw, spacer and stop bracket
(marked with a black/yellow striped label) shown in
Figure 12 on page 17.
Connecting the Operator to the High-Speed Power
Train
STEP 14.Attach the uni-ball coupling on the operator
connecting link to the interphase drive lever in the
high-speed base using the ¾-inch stainless steel pin
and cotter pin retained from Step 8. See Figure 14.
An adjustable locking rod (marked with a black/
yellow striped label) is furnished factory-connected
to the interphase drive lever. Turn the associated
¼-20 locknuts as required to raise or lower the
interphase drive lever enough to facilitate insertion
of the stainless steel pin.
STEP 15.After the pin is installed, remove the lower ¼-20
locknut that retains the adjustable locking rod, and
then remove and discard the adjustable locking rod
and locknuts. See Figure 14.

Connecting Conductors
STEP 16.
DANGER
Conductors must be de-energized and
grounded in accordance with standard system
operating practice. Failure to do so can result
in serious injury or death.
Attach the high-voltage conductors to their respective circuit-
switcher terminal pads using exible-conductor connections.
Observe the terminal-pad loading limits specied on the
catalog drawing. Use the following procedure for attaching
the conductors:
(a) Thoroughly wire-brush the current-transfer
surfaces of each connector and immediately apply a
liberal coating of Penetrox® A (available from
Burndy Corporation) or other suitable aluminum
connector compound to the brushed surfaces.
(b) Wire-brush each terminal pad and apply a coating of
PenetroxA.Then, boltthe connectorstotheterminal
pads.
(c) Prepare the conductors using established
procedures and clamp them in their respective
connectors.
Removing the Interrupter Containers
STEP 17. Remove the container from each interrupter as
follows:
(a) Remove and discard the ⅜ -16 zinc-plated serrated
hex nuts that run the length of the container.
(b) Remove and discard the ⅜ -16 ×⅞ -inch and two
⅜ -16 ×1-inch zinc-plated hex-head cap screws and
at washers that attach the upper container half to
the coupling end casting of the interrupter. Also,
remove and discard the ⅜ -16 ×⅞ -inch and two
⅜ -16 ×1-inch zinc-plated hex-head cap screws and
at washers that attach the upper container half to
the indicator-end casting of the interrupter.
(c) Pry the container halves apart with a at-head
screwdriver or other sturdy pry tool. The upper
container half can now be removed and discarded.
Slotted holes are provided so a rope or lifting sling
can be attached and the container half more safely
lowered to the ground.
(d) Remove and discard the ⅜ -16 ×⅞ -inch hex-head
cap screw and at washer that attach the lower
container half to the coupling-end casting of the
interrupter, and the ⅜ -16 ×⅞ -inch hex-head cap
screwand at washer thatattach thelowercontainer
half to the indicator-end casting of the interrupter.
Then, discard this container half.
(e) Remove and discard the foam-core inner liner
wrapped around the interrupter.

Setting up the Operator and Checkout
STEP 19.
CAUTION
Unauthorized changes should not be made in
the wiring of the operator. Should a control-
circuit revision appear desirable, it should be
made only on the authority of a revised wiring
diagram that has been approved by both the
user and S&C Electric Company.
Do not apply control voltage to the
operator at this time!
Perform the following set-up procedure on the
operator. (See Figures 16 through 18.)
(a) To avoid accidentally energizing the operator after
the external connections have been completed,
open the control power KNIFE switch, and then
swing the KNIFE switch retainer arm out of the way
by putting pressure on the red insulated retainer and
the black nylon retainer nut. The KNIFE switch
retainer arm will “pop up” and can then be swung
out of the way. See Figure 17 on page 22.
(b) Mark the conduit-entrance location for the control-
circuit wiring on the conduit-entrance plate in the
bottom of the operator enclosure. See Figure 16.
Remove the plate and cut out the necessary opening.
Apply sealant and replace the plate. Make up and
connect the entrance ttings, and verify the ttings
are properly sealed to prevent water ingress.
NOTICE
Make sure the polarity of the control circuit
is correct on dc-control voltage models.
Energizing the switch operator with polarity
reversed will cause damage to the operator
control circuit and will require repair or
replacement of the operator.
