Mounting the Switch Assembly
Upright Mounting Configurations
WARNING
Lift the switch using the lifting bracket provided. Do
not allow lifting slings to stress switch parts. Avoid
allowing the switch to swing while lifting.
Lifting the switch by the live parts or pole-unit bases
will damage the switch. Rough handling may cause
damage to the blades and contacts.
Failure to lift the switch properly can result in
switch damage, causing improper operation,
arcing, or electrical shock.
Note: For inverted mounting configuration, Step 3 is on
page 11. For triangular mounting configuration, Step 3 is
on page 12.
STEP 3. Switches in the upright mounting con guration
are provided with a retractable single-point
lifting bracket permanently attached to the
switch base. See Figure 2.
(a) Make sure the switch is fully closed.
(b) Attach lifting slings only to the single-point
lifting bracket.
(c) Lift the switch as shown in Figure 2 until the
lifting slings are just taut.
(d) Unbolt the switch base from the shipping
skid.
(e) Slowly and carefully lift the switch to the
proper mounting height.
(f) Guide the switch so the through-bolts
projecting from the utility pole slip into the
holes in the switch’s pole-mounting bracket.
(The pole-mounting bracket is provided
with a keyhole and an open slotted hole for
ease of installation.)
(g) Lower the switch so the pole-mounting
bracket bears down on the through-bolts.
(h) Securely tighten the through-bolts. Install
the two -inch diameter lag screws on the
front of the mounting bracket, diagonally
from each other. See Figure 2.
(i) Remove the lifting sling from the single-
point lifting bracket. Lower the lifting
bracket.

(j) If desired, a crossarm brace (user-furnished)
may be attached to the base. Mounting
brackets for crossarm braces must be
speci ed separately. Contact your local S&C
Sales Of ce for details.
CAUTION
To maintain proper electrical clearance,
make sure the lifting bracket is placed in the
retracted (lowered) position after installation.
Failure to do so may increase risk of
flashover.
