Operator Setup

Controller Access

The Controller in models SG and SG-D is located under the
operator's top cover.
To access the Controller, from inside the operator, fl ip the
two cover release latches up to unlock the operator's top
cover. Remove the cover to expose the Controller.
The Controller is protected by a plastic dust cover. To
remove the dust cover, loosen the cover's wing-screw and
lift the cover off.

AC Power Connection

All Linear gate operators are supplied with a power
disconnect switch to turn on and off the power available to
the operator (see Figure 8). Following wiring specifi cations
on Page 2, incoming power should be brought into the
operator and connected to the labeled pigtails from the
disconnect box.
WARNING
ALL AC ELECTRICAL CONNECTIONS TO THE POWER SOURCE AND
THE OPERATOR MUST BE MADE BY A LICENSED ELECTRICIAN AND
MUST OBSERVE ALL NATIONAL AND LOCAL ELECTRICAL CODES.
POWER SUPPLY MUST BE OF CORRECT VOLTAGE AND PHASE.
✓ NOTE: FOR SOLAR POWERED UNITS ONLY: The
APeX Controller's AC power disconnect switch does not
turn off the Apex DC power when connected to solar
panels. It will however, disconnect DC motor power.
Unplug the solar panel input on the front of the Apex
Controller prior to servicing the unit.
Proper thermal protection is supplied with the operator. The
motor contains a thermal overload protector to guard from
overheating the motor due to overload or high-frequency
operation. To reset the motor after an overload, press the
red button on the end of the motor after the motor has
cooled down.

Earth Ground

Install a ground rod and connect it to the operator's frame
in every gate operator installation. A good earth ground is
necessary to allow the Controller's built-in surge and lightning
protection circuitry to work effectively. The physical bolting
of the operator to the mounting pad is not suffi cient for
a good earth ground.
✓ NOTE: Do not splice the ground wire. Use a single piece of solid
copper 12 AWG wire between the ground rod and the operator.
1. Install an 8-foot long copper ground rod next to the operator mounting
pad within three feet of the operator.
2. Use a clamp to connect a solid copper 12 AWG ground wire to the
ground rod.
3. Route the ground wire to the operator.
4. Connect the ground wire to the operator's frame.
