2.1 High Voltage Connections
Use Table 1 to determine high voltage wire size requirements. The distance shown in the chart is
measured in feet from the operator to the power source. If power wiring is greater than the maximum
distance shown, it is recommended that a service feeder be installed. A separate power disconnect
must be installed at the operator. The wire table is based on stranded copper wire. Wire run
calculations are based on a 3% voltage drop on the power line, plus an additional 10% reduction in
distance to allow for other losses in the system.

Be sure wiring is installed in accordance with local codes.
Be sure to color code all wiring.
Connect the power wires to the high voltage terminal strip
as shown.
It is recommended that a surge suppresser be installed on
the high voltage power lines to help protect the operator
and circuit board from surges and power fluctuations.
If 3-Ph power is used to power a ½ HP unit, cap off one
leg of the power as shown below.
