• Connect the white wire to the incoming neutral lead.
• Connect the green wire to the ground.
Do not connect any of the AC power wires directly to the control board.

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 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 operator may be returned to service.
• Disconnect power at the fuse box BEFORE proceeding. Operator MUST be
properly grounded and connected in accordance with local electrical codes.
NOTE: The operator should be on a separate fused line of adequate capacity.
• 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. We recommend that you install an optional reversing edge
BEFORE proceeding with the control station installation.
• 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.
• BEFORE installing power wiring or control stations be sure to follow ALL
specifications and warnings described below. Failure to do so may result in
SEVERE INJURY to persons and/or damage to operator.
