Wiring the IntelliFlo

To connect the IntelliFlo to AC power:
1. Make sure all electrical breakers and switches are turned off before wiring motor.
2. Make sure that the wiring voltage is 230 VAC.
3. Use #12 AWG for wire runs up to 30 m or 100 feet and #10 AWG for lengths longer than 30 m or
100 feet. When in doubt use a heavier gauge (larger diameter) wire. Heavier gauge will allow the
motor to run cooler and more efficient.
4. Make sure all electrical connections are clean and tight.
5. Cut the wires to the appropriate length so they do not overlap or touch when connected.
6. Permanently ground the motor using the green ground wire, as shown below. Use the correct wire
size and type specified by National Electrical Code. Make sure the ground wire is connected to an
electrical service ground.
7. Bond the motor to the pool structure in accordance with the National Electrical Code. Use a solid. No. 8
AWG or larger copper conductor. Run a wire from the external bonding lug to the pool bonding structure,
as shown below.
8. Permanently connect the pump to a circuit breaker, two-pole timer, or relay in an automation controller
such as IntelliComm. The drive must be powered up to receive and respond to the RS-485 serial
communication from the automation system. Be sure that no other lights or appliances are on the same
circuit.
NOTE: When the IntelliFlo pump is started and stopped by removing power with a relay
or timer, a two-pole device should be used to apply and remove power to both of the red
power leads.
The IntelliFlo pump is designed to be permanently connected to its power source. Typically the pump
receives power directly from the circuit breaker. No contactor or motor starter is required. IntelliFlo can be
operated in "stand-alone" mode, starting and stopping when power is applied or removed. When the drive
powers up it will return to the mode and run status that it was in when power was removed. This setup
maybe appropriate if you need to use existing relays or timers.
9. For wiring of the communications port, see page 23.
