Installation procedure

Personal injury . Sheds on epoxy encapsulation have
sharp edges . Wear protective gloves when handling the
unit . Failure to do so can result in cuts and abrasions .

Check-out procedure

1. Check data plate . Make sure that ratings on the data
plate are correct for the planned installation.
2. Visually inspect the switch . Visually inspect the
switch for any damage to bushing sheds, terminals,
tank, of trip handle.
3. Install the switch . 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).
Hazardous voltage . Solidly ground all equipment . Failure
to comply can result in death, severe personal injury,
and equipment damage .

Three-wire control

Remote control of the Edison capacitor switch is supplied
T223 .2
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 .
