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. When large gauge wire is
used, a separate junction box must be installed for the operator connection. The wire table is based
on stranded copper wire. Wire run calculations are based on a 110 VAC power source with a 3%
voltage drop on the power line, plus an additional 10% reduction in distance to allow for other losses
in the system.

• Route incoming high voltage
power through conduit and
into the operator as shown in
Figure 19.
• Be sure wiring is installed in
accordance with local codes.
Be sure to color code all
wiring.
• Connect power wires 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.
Figure 19
• Note: For 230 and 460 Volt 3-phase input, use only two legs of the incoming 3-phase power.
