POWER WIRING INSTALLATION
Wiring Specifications (STRANDED COPPER WIRE)
On a Dual Gate System, each unit must be installed on ITS OWN separate circuits.
NOTE: Calculated using NEC guidelines. Local codes and conditions must be reviewed for suitability of wire installation. All power
wiring should be dedicated and protected. Location of primary power disconnect should be labeled.
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 unit 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.
