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 and locking-out the power. 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. 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.
• 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.

POWER AND GROUND
Power and control wiring must be run in separate conduit in
accordance with national and local electrical codes. Must use
14 AWG or heavier wire for power wiring. Use conduit knockouts
for wiring as indicated on the electrical box labels.
Remove the operator cover.
Attach power and ground wires to appropriate terminals.
IMPORTANT NOTE:
This operator must be properly
grounded. Failure to properly ground the operator could
result in electric shock and serious injury.
NOTE:
In
some installations, such as a through-wall-installation,
the rotation of the motor and logic board may have to be changed.
1. Locate the MOTOR DIRECTION jumper on the logic board.
Remove jumper and relocate from STD to REV.
2. Relocate the safety limit switch (SLS) to the opposite side.
3. Remove CLOSE/OPEN decal and reattach appropriately.

Run power wires to electrical box according to national and
local electrical codes.
ON THREE PHASE MACHINES ONLY: Incorrect phasing of
the power supply will cause the motor to rotate in the wrong
direction. To change motor rotation, exchange incoming
power leads L1 and L2.

* Maximum wire gauge that can be connected to the operator’s
terminal is 12 AWG. When a larger wire gauge is required, the wire
must be gauged down to 12 AWG. USE COPPER WIRE ONLY.
