Wiring the IntelliFlo 4
To connect the IntelliFlo 4 to an AC power source:
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 100 feet and #10 AWG for lengths longer than 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. 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. The drive
controls the starting and stopping of the pump. If the IntelliFlo is connected to an automation system, such
as EasyTouch or IntelliComm, the drive must be powered up to receive and respond to the RS-485 serial
communication from the automation system. However, the pump 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 pinouts for the communications port, see page 11.
