Step 42
Remove and retain the eight 10-32
⁵⁄₈
inch
stainless-steel round-head machine screws that
secure the motor cover to the motor housing.
Remove the motor cover, and set the cover
and screws aside in a protected area. See
Figure 39.
Step 43
Connect the conduit to the
¹⁄₂
-14 NPT tap on
the side of the motor housing, and pull the
wires through into the motor housing. Use
watertight fi ttings to make all connections. See
Figure 40.
Step 44
Following the supplied wiring diagram, make
the necessary wiring connections to the terminal
block in the motor operator. See Figure 57.
DO NOT
remove the jumper between Terminals
8 and 9. Train the motor wiring towards
the center of the housing so that the motor
wiring does not come in contact with the motor
cover. Bend the terminal lugs if necessary. Then
replace the motor cover and secure it using the
10–32
⁵⁄₈
-inch round-head machine screws
retained from Step 50.
NOTICE
If control power is lost while the Mark
VI Circuit-Switcher interrupter charging
motors are closing and charging the pole-
units, the jumper between Terminals 8 and
9 will force the motor operators to “reset” to
the beginning of their charging cycle when
control power is restored.
Step 45
Replace the motor cover and secure it using the
screws retained from Step 43.
Ç
CAUTION
DO NOT
connect the wiring from the Mark
VI CS-1A Switch Operator at this time. Keep
the wiring clear of any moving parts inside
the operator.
