Installation
(c) Remove and discard the two ⅜–16×1-
inch and one ⅜–16×⅞-inch zinc-plated
hex-head cap screws and at washers
that attach one of the container halves
to the indicator end casting of the
interrupter. Do not remove the remaining
⅜–16×⅞-inch cap screw—it’s needed to
temporarily retain the other container-
half.
(d) Pry the container halves apart with a
at-head screwdriver or other pry tool.
One of the container halves can now be
removed and discarded—slotted holes
are provided so a rope or lifting sling can
be attached and the container safely
lowered to the ground.
(e) Remove and discard the remaining
⅜–16×⅞-inch hex-head cap screw and
at washer that attach the other
container half, then discard this
container half.
(f) Finally, remove and discard the foam-
core inner liner wrapped around the
interrupter.
Step 29
Remove and discard the protective wrappers
from each insulating support column.
Setting up the Operator and
Checkout
Step 30
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 Figure 30 on page 26, Figure 31
on page 27, and Figures 32 and 33 on page 30.
(a) To avoid accidentally energizing the op-
erator after the external connections
have been completed, open the control
power knife switch. Swing the knife
switch retainer arm out of the way by
putting pressure on the red insulated re-
tainer and the black nylon retainer nut.
The knife switch retainer arm will “pop
up” and can then be swung out of the
way. See Figure33 on page 30.
