IntelliFlo VS-3050 Installation and User’s Guide

Wiring the IntelliFlo VS-3050

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 ± 10%.
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. Permanently connect the pump to a non-GFCI circuit breaker, two-pole timer or relay in an automation
controller such as IntelliTouch, EasyTouch or 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: The IntelliFlo pump will not function properly when powered from a GFCI device.
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 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 pinouts for the communications port, see pages 11, 14 and 15.
