Wiring the IntelliFlo ® VS
To connect the IntelliFlo ® 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 (30 m) and #10 AWG for lengths longer than 100 feet
(30 m). 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/yellow ground wire, as shown below. Use the
correct wire size and type specified by EU Electrical Codes. Make sure the ground wire is
connected to an electrical service ground.
7. Bond the motor to the pool structure in accordance with the local regulatiosn. 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.
NOTE: When the IntelliFlo ® VS 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 ® 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.
