SECTION 2 - AC INPUT POWER TO OPERATOR(S)
Before attempting to connect any wiring to the operator, be sure that the circuit breaker in the electrical panel is in the OFF
position. Permanent wiring must be installed to the operator as required by local electrical codes. It is recommended that a
licensed electrical contractor perform this work.
Since building codes vary from city to city, we highly recommend that you check with your local building department prior
to installing any permanent wiring to be sure that all wiring to the operator (both high and low voltage) complies with local
code requirements.
THIS GATE OPERATOR MUST BE PROPERLY GROUNDED!!
2.1 AC Power Wire Runs and Terminal Connection
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 an AC 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 AC power
wire through the high voltage
conduit and run wire to the
operator electronic box.
•
Be sure wiring is installed in
accordance with local codes.
Be sure to color code all
wiring.
•
It is recommended that a
surge suppressor be installed
on the high voltage power
lines to help protect the
operator and circuit board
from surges and power
fluctuations.
•
Secondary operator
MUST
have it’s own input power
wire when installing dual gate
operators (See next page).
DANGER
HIGH VOLTAGE!
“Optional” Heater Installation Note:
When installing a heater, refer to the
“high voltage AC power wire size and distance limitations”
table on the instruction sheet with the heater kit for AC power wire run limitations.
Never
run low voltage rated wire insulation in the same
conduit as high voltage rated wire insulation.
This table illustrates the high voltage AC power wire size and distance limitations.
