This kit is designed for the 1600 model barrier gate operators only. For cold weather climates where temperatures routinely drop
below 40°F (4°C). A built-in thermostat will automatically control the temperature inside operator housing.
DO NOT use the “high voltage wire size and distance requirements” table in the Installation/Owner’s manuals to determine the high
voltage AC input power wire size and distance requirements for the barrier gate operator because of a much greater current draw
when using the heater. Use the table below to determine the wire size and distances for your chosen barrier gate operator when a
heater is installed. EACH operator should have a “Dedicated” circuit breaker at the power source.
If the high voltage AC input 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. Wire run distances
are based on NEC guidelines for copper wire allowing a maximum 3% voltage drop on the line. The calculated distance was then
further reduced by 10% to allow for other loses in the system. Never run low voltage rated wire insulation in the same conduit as
high voltage rated wire insulation.
