STEP 1
Before anchoring the chassis to the concrete
pad, make sure the gate and operator are
LEVEL and PARALLEL. Minimum distance
between the operator and gate is 3”.
Note: Before starting the installation procedure;
• Open and close the gate manually, making sure there is sufficient space between
the gate and adjacent walls.
• Check that the wheels are turning freely on the track and there are no restrictions
while pushing the gate to the open and closed positions.
• Confirm that there is adequate spacing for the guide rollers and that there are no
restrictions throughout the travel of the gate.
STEP 2
Attach the operator to the concrete pad
using Red Head 1/2” x 3-1/2” Anchors.
Follow the manufacturers instructions for
proper installation. Refer to page 11 for hole
center dimensions.

The Gate Operator requires a single phase AC
line to operate the gate and charge the batteries.
A. Turn off the main switch or breaker for
the power line being used.
B. Move the selector switch on the Incoming
Voltage Selector to the proper position
(115 for 110 to 120VAC, 230 for 200 to 240VAC).
C. Connect the incoming power wires to the
terminals as shown in the illustration.
D. Turn on the main switch or breaker once
the installation is ready for final
adjustments.
E. To verify that there is AC power to the
system, check that the ‘Charger’ LED on the
Control Board is on.

Tips for proper ground installation
A good ground in a gate operator
installation will minimize or prevent damage
to the operator cause by natural events such
as lightning strikes.
The following will provide a guideline for
proper grounding:
1. Use a ground rod to provide a ground
reference.
2. Consult your city code and be aware of
under-ground services in the site of the
gate operator to prevent inconveniences.
3. Use always a single bonding point for
grounding.
4. All ground wires must be as short and as
thick as possible.
5. Prevent unnecessary turns or loops in all
ground wires.

Caution – Do not connect the power harness to the board
until the installation is ready for verification.
