Congratulations on selecting a Nice swing gate actuator for your gate opener system. With proper selection,
system design, installation, and maintenance this actuator should provide years of reliable operation. This
manual covers ONLY the installation of the actuator.
IMPORTANT!
For control box installation, wiring, operation, programming, maintenance, and all safety information, refer
to the appropriate 1050 control box installation manual used for the system being installed.

Below is a list of tools suggested for installation of the 3501 actuator:
• Welder (option for gate bracket)
• Drill and assorted bit sizes
• 1/2” and 3/8” wrench and/or nut driver
• Basic hand tools (screwdrivers, pliers, etc..)
• Bubble Level (for leveling actuator)
• Measuring tape (for locating post position)
• 1/8” and 5/32” hex keys (for set screws)
IMPORTANT!
• The gate operator installation is NOT a “do-it-yourself” project. Contract a qualied gate operator instal-
lation company to install this system to ensure a safe and reliable installation.
• It is the responsibility of the property owner to ensure the installer is qualied to carry out the installation
in a safe and professional manner.
• Consult local government agencies for up-to-date rules and regulations to satisfy licensing, codes or
regulations that regulate automated gate system design and installation.
• The gate for which the gate operator is intended to be used should itself be installed correctly so that it
is level and plumb and the gate opens easily and evenly.
• Note that Nice swing gate systems are not intended for installation on an incline.
SECTION 2: INSTALLATION SAFETY
SECTION 3: TOOLS NEEDED FOR INSTALLATION
WARNING!
READ ALL SAFETY INFORMATION IN THE CONTROL BOX INSTALLATION MANUAL WHEN
INSTALLING A SWING GATE SYSTEM!
BE AWARE OF ALL MOVING PARTS AND AVOID CLOSE PROXIMITY TO ANY PINCH POINTS.

1. Determine the angle that the gate will travel to (A) in IMAGE 1-1.
2. Select the coordinates (B & C) as shown in the IMAGE 1-1. Distances of “B” are from the center of gate
hinge to the center of the mounting post. Longer gates should operate at slower speeds.

• The top of the post should be 2” above the centerline of the
location where the gate attach bracket will be mounted to the
gate (IMAGE 2-1).
• The gate attach bracket should be mounted to a structural
member on the gate. DO NOT attach the bracket to pickets.
• The mounting post should be square to the gate in the closed
position and level for proper operation.
• Conduit should be considered at this time for cable routing
from the control box to the chassis assembly

If security is of the utmost importance then the bracket may be connected to the actuator arm using the
1/2” x 3” bolt, washers, and lock nut (IMAGE 8-1).
However, to enable quick manual opening of the gate in case of power failure, it is recommended to use

11 RUN ACTUATOR CABLE(S) TO CONTROL BOX
Run the cable of the actuator closest to the control box through a hole (with rubber grommet) in the bottom
on the control box.
If a dual gate installation:
1. Dig a trench across the driveway deep enough to accommodate the longer harness cable from the
actuator furthest from the control box.
2. Run the cable through an appropriate conduit and lay this in the trench.
3. Cover the trench and use asphalt patch if needed.
4. Run the 2nd cable into a hole (with rubber grommet) into the bottom of the control box.
NOTE: Ensure the cable(s) reaches into the control box sufciently to reach the MOTOR inputs on the
control board.

instruction. Refer to the control box installation manual for instructions on installing the control box and
applying power to the control board and the actuator motor.
NOTE: Apply power to the control board, but do not put the control board through the “Learning”
process described in the Control Box installation manual until after the limit collars have been adjusted
per INSTRUCTION 14 in this manual.

IMPORTANT!
There is a “motor switch” on the bottom of the drive chassis used to de-energize the motor for manually
opening the gate. However, if this switch is inadvertantly turned OFF during installation, the motor will
not operate. See INSTRUCTION 16, IMAGE 16-1 for switch location and ON/OFF orientation in case this
is an issue.
