4.7 Motor Wir ing Or der for Corr ect Rotation
WARNING If the pump wires are in the wrong order, the motor will run in reverse. This may
cause the impeller to spin off and “crash”, causing damage. Test the pump for proper direction
before allowing it to come up to full speed (takes 15 seconds).
The proper direction is CLOCKWISE when viewed from the REAR of the motor.
WARNING Do not run the pump dry. Fill the pump at least half-way with water before testing for
direction.
The motor receives 3-phase AC power from the controller. This requires three power wires. If they are
not in the proper order, the motor will rotate in reverse direction.
The motor wires inside the motor junction box are labeled L1, L2 and L3. (L1 is closest to the motor.)
Connect each one to the corresponding “pump” terminals in the controller.
To make secure connections in the motor junction box, invert one of the two U-brackets on each terminal
bolt. The brackets should couple together so they trap the wire securely.
Confirm the direction
When first starting the motor, remove the rubber plug from the rear-center of
the motor, and observe the shaft rotation. It should turn CLOCKWISE as viewed from the rear of the
motor.
The motor starts very slowly
It takes 15 seconds to reach full speed. If the direction is reversed,
STOP THE PUMP before it reaches full speed, or the impeller may spin off and “crash”.
If the direction is reversed, exchange ANY TWO of the power wires, either at the motor or in the
controller.
Alternative: Connect the power wires to the controller in ANY random order. Apply power. Observe the
pump shaft rotation as the pump starts. If the direction is wrong, stop the pump immediately and
exchange ANY TWO of the power wires.
4.8 Pum p Motor Bonding and Grounding
WARNING Electrical wiring should be performed by a licensed electrician in accordance with
local, state and national codes. Be certain that the motor frame is grounded. Do not connect to
electric power supply until unit is permanently grounded to earth and bonded to the pool
structure.
Bonding
TO REDUCE RISK OF ELECTRICAL SHOCK, a bonding connector is provided for bonding
to metal water pipes, metal rails, or other metal within 5 feet of the swimming pool. All local points
should be bonded with a #8 AWG wire. As required by National Electrical Code Article 690-22, the pump
motor must be electrically bonded to the pool structure (reinforced bars, etc.) by a solid copper conductor
not smaller than #8 AWG via an external copper bonding lug on the pump motor.
GROUNDING
TO REDUCE RISK OF ELECTRICAL SHOCK, connect ground wires to grounding screw
located in the motor. Use no smaller than a #12 AWG wire.
