16 S&C Instruction Sheet 765-510
Installing the Operating Handle
NOTICE
If ordered with provisions for power operation with the
6801M Automatic Switch Operator (catalog number
suffix “-M”), omit steps 10 through 13 and proceed
with the installation steps described in the 6801M
Operator Installation Instructions (S&C Instruction
Sheet 1045M-510). Once the 6801M operator has
been installed, proceed with step 14 of this instruction
sheet.
STEP 10.
●
Install the operating-handle assembly on the
lowest section of vertical operating pipe at the
location indicated on the erection drawing.
Make sure the cutting tip of the piercing set
screw in the operating-handle assembly
does not protrude through the clamp when
installing the assembly on the vertical operating
pipe. After the operating-handle assembly is in
place, tighten the piercing set screw on the
operating-handle assembly, piercing the pipe.
Continue turning until a fi rm resistance is felt.
See Figure 11.
Slide the foot-bearing assembly onto the
lowest vertical operating pipe section and bolt it
to the pole at the position shown on the erection
drawing. At the same time, use one of the
mounting bolts to attach one end of the ground-
ing strap (the end with the grounding connector
attached) to the foot-bearing assembly
■
.
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. See Figures 9 and
10 on page 15.
STEP 11.
Fasten the free end of the grounding strap to the
lowest vertical operating pipe section a few
inches above the operating-handle assembly
(or key interlock) with the U-bolt connector
provided for this purpose. Then, connect the
lower end of the strap to a suitable earth ground,
fastening the grounding connector provided at
that end of the strap
