that the voltage to be used matches the voltage of the operator.

If you have any questions about the requirements for proper
installation of this gate operator contact technical support at
800-421-1587.

Always Check the Gate’s Action

It’s very important before installing the gate operator to
make sure the gate’s swing is free and level throughout
the entire swing path. If the gate does not seem to
operate properly, it may affect the operator performance
or greatly shorten the life of the unit. The gate should
also be designed so that airflow is ample to prevent
wind resistance and drag.

Wiring Specifications

The Model LRA Residential Linear Actuator is designed
to open and close a light-duty residential swing gate. The
operator can be used in left-hand or right-hand swing gate
installations on gates weighing up to 600 pounds.

The operator is connected by a cable to an APeX electronic
controller, which provides all connections for input and
entrapment detection devices. The Controller is housed in a
separate enclosure and contains a built-in radio receiver for
wireless activation by remote control transmitters.

Brackets attached to the gate and gate hinge post are for
mounting the operator and to provide a mechanism to move
the gate.

When the operator activates, the worm drive in the linear
actuator changes the fixed distance between the two
brackets that the operator is mounted on. When the operator
pulls the two brackets closer together, the gate opens. When
the operator pushes the two brackets farther apart, the gate
closes (see Figure 1).

Adjustable magnetic limit switches in the operator detect the
open and closed positions of the gate.

WARNING

This operator is intended for installation only on gates used for
vehicles. Pedestrians must be supplied with a separate access
opening. The pedestrian access opening shall be designed to
promote pedestrian usage. Locate the gate such that persons
will not come into contact with the vehicular gate during the
entire path of travel of the vehicular gate.

Refer to the following steps for details on power and
accessory wiring for the operator.

Examine Figure 2 for details of the required mounting locations
for the two brackets. The brackets must be mounted at the
correct locations to allow the operator to open the gate at a 90
degree angle and to ensure the operator functions smoothly.

The brackets must also be mounted level in respect to each
other so the operator’s front and rear mounting points are
vertical and not offset at an angle.

WARNING

The gate must be installed in a location so that enough
clearance is supplied between the gate and adjacent structures
when opening and closing to reduce the risk of entrapment.
Swing gates shall not open into public areas.

Measure approximately halfway up the gate height and determine 1.
good strong spots located in the required areas to mount the brackets
on the post and gate.

Using Figure 2 as a guide, mark the locations on the post or pillar and 2.
the gate for the two mounting brackets.

✓ NOTE: Depending on the gate design, an additional reinforcing

plate welded to the gate may be required to provide a good spot to
mount the gate bracket.

Figure 2. Required Bracket Locations

Post Bracket Installation

✓ NOTE: When installing the post bracket on a round post or masonry

pillar, use improvised methods (additional plate with lag bolts and
anchors, concrete wedge anchors, U-bolts, etc.) to securely fasten
the bracket.

For square gate posts:

Tack weld the post bracket to the post at the marked spot and 1.
double-check its level and height.

Finish welding the post bracket to the gate post.2.

After the welding is completed and the post bracket has cooled, 3.
install the post bracket pin as shown in Figure 3.

Gate Bracket Installation

Before welding the gate bracket, be sure the centers of the
operator mounting holes on the brackets will end up 29-1/2”
apart when the gate is fully closed.

Tack weld the gate bracket to the gate at the marked spot and 1.
double-check its level and height.

Finish welding the gate bracket to the gate.2.

After the welding is completed and the gate bracket has cooled, 3.
snap the limit switch magnet assembly onto the gate bracket (see
Figure 4).

From the top side of the gate bracket, slide the load bushing into the 4.
bracket hole.

Alternate method to locate the gate bracket:

1. Hold the gate bracket with the magnets installed onto the LRA
traveler.

2. Run the unit to the full open position.

3. Place the rear of the arm onto the post bracket.

4. Manually fully open the gate.

5. Position the gate bracket in the required position.
