Installation
Installing the Rotating Operating
Handle
When a key interlock is used (standard minor
modification suffix “-S6”), skip to Step 18 on
page 29.
When a Type AS-1A Switch Operator is used
(standard minor modification suffix “-S8” or
“-S9”), refer instead to S&C Instruction Sheet
769-500 for installation instructions. When an
S&C 6801M Automatic Switch Operator is used
(standard minor modification suffix “-S16”),
refer instead to S&C Instruction Sheet 1045M-
510 for installation instructions.
Step 15
Back the piercing set screws out of the handle
yoke and slide the handle assembly up the
pipe until it is in the location indicated on the
erection drawing. There should be 6 to 8 inches
of operating pipe below the operating-handle
assembly. See Figure 14.
Tighten the piercing set screws on the
operating-handle assembly enough to hold the
handle in place, but DO NOT pierce the vertical
operating pipe.
Step 16
Slide the foot-bearing assembly onto the lowest
section of pipe at the position shown on the
erection drawing. See Figure 15. Adjust the
operating handle assembly until it is two to three
inches above the foot-bearing assembly. Tighten
the piercing set screws, piercing the pipe, and
continue turning until a firm resistance is felt.
At the same time, use one of the mounting bolts
to attach one end of the grounding strap (the
end with the grounding connector attached)
to the foot-bearing assembly. The grounding
recommendations in this document may
differ from the standard operating and safety
procedures of certain electric utility companies.
Where a discrepancy exists, the operating
procedures of the electric utility apply.
If necessary to compensate for the taper
of the wood pole and to keep the vertical
operating-pipe aligned and plumb, shift the
guide bearings toward or away from the pole.
Alignment slots are provided for this purpose.
