Follow locally approved installation
procedures. Mounting hardware is available for pole
mounting as an accessory.
High-voltage connections
1.
Ground the switch .
Make the ground connection to
the ground connector located on the switch bracket of
the switch.
2.
Make line connections .
Connect the primary leads
to the switch terminals. The universal clamp-type
terminals accommodate AWG No. 8 solid through 2/0
stranded conductor.
3. Recommended torque levels for line and load terminal
hardware are 20–22 ft-lbs (27.1–29.8 N-m) not to exceed
30 ft-lbs (40.7 N-m).
WARNING

Three-wire control
Remote control of the Edison capacitor switch is supplied
by a single-pole, double-throw switch (three-wire control)
supplied by the customer. Any manual switch, relay contact,
time switch, voltage-, current- or photo-electric-controlled
switch, or similar device can be used, provided the control
circuit is energized for a minimum of 80–100 ms for each
operation.
Eaton requires a 10-second cool-down period
between open and close operations to ensure the
switch coil does not overheat or become damaged .
A connection diagram for a standard three-wire control is
shown in Figure 2.
