Crossarm Mounting
This configuration is intended for application
to a double crossarm structure.
This is the preferred arrangement if three
units are to be mounted.
1. Remove the four 3/8" X 5/8" bolts from top
mounting flange (8) and use to fill the four
holes on the cover (9).
2. Refer to Figure 4-8 for assembly detail
and Table 2-1 for torque specifications.
• Orient the insulator (1) so the skirts
will shed water towards the rectangular
steel adapter plate (2) and assemble
using two 3/8" X 1" bolts and split lock
washers (3) as shown.
• Assemble the mounting bracket (4)
to the opposite end of the insulator
(1) using two 3/8" X 1" bolts, split lock
washers and flat washers (5) as shown.
• Attach the insulator/bracket/adapter
plate to the four threaded bosses on
the top of the body of the recloser as
shown. Use four ss 3/8" X 1-1/4" bolts,
flat washers and lock washers (6).
3. Using a nylon sling, sling the unit as
shown in Figure 4-7.
CAUTION: Do not use a metal sling or
chain as this may damage the unit.
4. Using suitable means, lift the unit into
position.
5. Install the back plate (7), and four 3/8"
X 7-1/2" carriage bolts/lock washers/
and square nuts. Adjust the bolt
spacing as necessary to fit the crossarm
arrangement.
6. Tighten the hardware per Table 2-1.
NOTE: Make sure the terminal L brackets
(2-hole NEMA pads) are not bent in any
angle. Terminal L bracket nuts, sixteen
screws around the recloser and six screws
around the vacuum interrupter are not to be
removed or re torqued by any means. The
integrity of the contacts is compromised if the
above factory standard torqued hardware is
tampered.
