to the interphase drive.
Step 31
Perform nal checkout as detailed below:
NOTICE
Check the following. Failure to do so can
result in damage to the circuit-switcher
when operated.
(a) At each transition box check that:
• The operating rod holding bracket, stop
bracket, and spacer have been removed
from the interrupter. See Figure 34.
• The interrupter coupling has been con-
nected to its insulated operating rod
link. See Figure 17 on page 20.
• When the optional remote gas-density
monitor is present (Catalog Number
Sufx “-R”) make sure connections are
made according to Instruction Sheet
716-530.
(b) At each interrupter make sure:
• That both interrupter container halves
and all associated packing and hardware
have been removed
(c) In the high-speed base:
• Each insulated operating rod is con-
nected to the interphase drive. See
Figure 35.
• The interphase drive lever has been
connected to the operator uni-ball cou-
pling. See Figure 36 on page 32.
• The adjustable locking rod attached
to the interphase drive lever has been
removed. See Figures 34 and Figure 36
on page 32.
(d) In the switch operator make sure:
• Correct polarity has been observed
on dc-control-voltage models.
See Figure37 on page 32.
• Check the open and close motor
contactors and surge suppressor to
ensure all electrical connections are
secure, and that all contactors and
surge suppressors are fully-seated in
their mounts. See Figure 38 on page 32.
• That any optional “ice cube” style
relays (used for Catalog Option “-P”
and “-T2”) are fully seated. See Figure
38 on page 32.
(e) All other pinned connections have been
made and all bolted connections have
been securely tightened.
