STANDARD CONTROL BOX

MOUNT THE CONTROL BOX
The control box MUST be mounted within 5 feet (1.52 m) of the gate operator.
Mount the control box as high as possible for best radio reception. Make sure the
control box is level. NOTE: The expansion board DOES NOT need to be removed for
a wall or column mount installation.

Remove the screws and open the control box.
2
Disconnect the connector labeled "Main Board" on the expansion board.
3
Remove the expansion board by removing the screws.
4
Select the mounting holes and remove the knockouts using a screwdriver and
hammer.
5
Secure the control box to mounting surface.
A. Column: Use the provided screws (4).
B. Wall: Use the provided screws (4).
C. Post: Use U-bolts and rubber washers (not provided) to ensure a watertight
seal. Make sure the U-bolts do not protrude more than 3/4 inch from the
