CAUTION
The operator directly drives the interrupters open and
closed through a simple high-speed power train leading
from the top of the operator, through a horizontal
interphase linkage enclosed in a steel-sheathed box-type
base, and to the reciprocating-action insulated operating
rods that pass through the center of the insulating support
columns . Permanently lubricated bearings are used
throughout the power train . The high-speed base has
been fully pre-assembled and adjusted at the factory .
DO NOT disassemble the high-speed base or high-
speed power train. Damage to the high-speed base and
personal injury may result .
STEP 5.
Loosely bolt the high-speed base to the support
arms using the ½ -13 × 2-inch hex-head galvanized
steel cap screws, fl at washers, and self-locking hex
nuts furnished. Lubricate the bolts to facilitate
tightening. Use a level to verify the high-speed base
is horizontal, both lengthwise and sideways. Adjust
the lower set of anchor-bolt nuts at the pedestals to
achieve level. Refer to the catalog drawing for
details. See Figure 3 on page 12 for anchor-bolt nut
detail.
STEP 6.
Attach the support brace to the support arms, using
the ½ -13 × 2-inch hex-head galvanized steel cap
screws, fl at washers, and self-locking hex-nuts
furnished. See Figure 1 on page 10 and the catalog
drawing. Lubricate the hardware to facilitate
tightening.
STEP 7.
Check the lower set of anchor-bolt nuts at each
mounting pedestal to verify all nuts are in contact
with the bottom of the pedestal. See Figure 3 on page
12. Hand-tighten the lower anchor-bolt nuts as
necessary. Then, securely tighten the upper set of
anchor-bolt nuts at each mounting pedestal.
