STEP 7
EARTH GROUND ROD
Use the proper earth ground rod for your local area. The ground wire
must be a single, whole piece of wire. Never splice two wires for the
ground wire. If you should cut the ground wire too short, break it, or
destroy its integrity, replace it with a single wire length.
1. Install the earth ground rod within 3 feet (.9 m) of the operator.
2. Run wire from the earth ground rod to the operator.
NOTE: If the operator is not grounded properly the range of the remote
controls will be reduced and the operator will be more susceptible to
lightning and surge damage.
STEP 8
POWER WIRING
To reduce the risk of SEVERE INJURY or DEATH:
• ANY maintenance to the operator or in the area near the operator
MUST NOT be performed until disconnecting the electrical power (AC
or solar and battery) and locking-out the power via the operator
power switch. Upon completion of maintenance the area MUST be
cleared and secured, at that time the unit may be returned to service.
• Disconnect power at the fuse box BEFORE proceeding. Operator
MUST be properly grounded and connected in accordance with
national and local electrical codes. NOTE: The operator should be on
a separate fused line of adequate capacity.
For dual gate applications, power will have to be connected to each operator. Main power supply and control wiring MUST be run in separate
conduits. An optional Transformer Kit (Model 3PHCONV) can be used to change the input voltage (208/240/480/575 Vac) to an output voltage of
120 Vac (refer to Accessories). NOTE: If using an external receiver use shielded wire for the connections and mount the receiver away from the
operator to avoid interference from the operator.

INSTALLATION
• ALL electrical connections MUST be made by a qualified individual.
• DO NOT install ANY wiring or attempt to run the operator without
consulting the wiring diagram.
• ALL power wiring should be on a dedicated circuit and well
protected. The location of the power disconnect should be visible
and clearly labeled.
• ALL power and control wiring MUST be run in separate conduit.
