MOUNTING GATE OPERATOR

For safety reasons, the Power Fail Operation Option is shipped with the battery unconnected to
the system.
Do not connect the battery until all other installation and alignment
procedures have been completed. Failure to observe this warning may result in the Power
Fail Operation Option moving the gate at unexpected moments.
To avoid injury, always turn off the unit power switch before working on gate.
After attaching the conduits to the control box, make sure that: a) the conduits fold to the right
during control box closure; and b) the control box swings freely open or closed.
1. Mount the cabinet on the cement pad using the previously installed anchors. Be sure the
operator mounting is level and square, and that the gate operator access door faces away
from the driveway (see Typical Installation, Figure 1).
2. Slightly loosen the mounting screws of the control box clear plastic cover. Slide the
cover out.
3. Swing the control box open fully to allow connection of the conduits. Run the conduits
through the bracket in the lower back of the control box.
4. Cut excess conduit and use 90 degree conduit fittings to attach conduits to the control box.
Note: the input power conduit need not go through the bracket and can be attached to the
control box directly.
B.

CONNECTING POWER

Ensure that the AC power circuit breaker is turned off before wiring power to the switchbox.
Run power cables through the conduit to Gate Operator, then connect wires to the switch box (see
Figure 3).
1. Wire nut the hot (black) wire to the black pig tail.
2. Wire nut the neutral (white) wire to the white pig tail.
3. Wire nut the ground (green) wire to the green pig tail.
4. Dress all wiring inside the switch box and install cover.
