To reduce the risk of SEVERE INJURY or DEATH:
l
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.
l
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.
l
ALL electrical connections MUST be made by a qualified individual.
l
DO NOT install ANY wiring or attempt to run the operator without
consulting the wiring diagram.
l
ALL power wiring should be on a dedicated circuit and well protected.
The location of the power disconnect should be visible and clearly
labeled.
l
ALL power and control wiring MUST be run in separate conduit.
Step 4 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 control box.
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 5 Wire the Operator Arm to
the Control Board
1.
Choose a knockout in the bottom of the control box.
2.
Insert the operator cable through the provided watertight connector.
3.
Insert the operator cable and watertight connector into the knockout.
4.
Slide the connector nut onto the operator cable.
5.
Connect the operator cable wires to the connector according to the
colored label on the connector (white to white, red to red, etc.).
6.
Plug the connector into the GATE 1 terminal on the control board as
shown.
