SECTION 2 - AC 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!!
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 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.
Never
run low voltage rated wire insulation in the same conduit as high voltage rated wire insulation.
Typical Grounding Sources

IMPORTANT:
Ground wire shown without

ground wire is protected from being
touched or electrical shock could occur!
“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
specific
heater kit for AC power wire run limitations.
“Optional” High Voltage Kit Installation Note:
When installing the high voltage kit for 208/230/460/575 VAC input power,
refer to the
“high voltage AC power wire size and distance limitations”
table on the instruction sheet with the
high voltage kit (P/N 2600-266) for AC power wire run limitations.
