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 operator 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.

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.
1
Remove the operator cover.
2
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.
3
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.

VOLTAGE SELECTION

For all operators except for 575V 3 Phase operators, follow the
steps below. The motor harness is connected to the power board
at the factory on all 575V 3 Phase operators.
1
Locate motor harness inside of the electrical box.
2
On the POWER BOARD find the appropriate receptacle
matching the incoming line voltage. Remove the voltage label
and apply to the inside of the electrical box for future
reference. Insert the motor harness fully until locked in place.

Single Phase
• 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.

* 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.
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 sensing limit switch (SLS) to the opposite side.
3. Remove CLOSE/OPEN decal and reattach appropriately.

Fusing on the 3-Phase Power Board is not field-replaceable. An
Open Fuse indicates that the 3-Phase Power Board is damaged
and must be replaced. Failure to replace the complete 3-Phase
Power Board may result in additional damage to the Operator.
