Connecting IntelliFlo VS to a SunTouch System
The IntelliFlo VS can be controlled by a SunTouch system via the RS-485 communication cable
(P/N 350122). To connect the two wire RS-485 cable from the IntelliFlo VS drive assembly to the
motherboard located in the SunTouch Power Center:
WARNING - Switch OFF main system power to the SunTouch Power Center before making any connections.
To access the SunTouch Power Center electronics compartment:
1. Unlatch the front door of the SunTouch Power Center, and open the door.
2. Loosen the retaining screw on front panel. Open the hinged front panel to access the electronics
compartment.
3. Route the two conductor cable up through the Power Center grommet opening located on the left
side, and up through the low voltage raceway to the motherboard.
4. Strip back the cable conductors ¼ in. Insert the wires into the screw terminals (provided in the kit).
Secure the wires with the screws. Make sure to match the color coding of the wires; Yellow = +DT,
Green = -DT.
5. Insert the connector on the COMPORT (J11) screw terminal on the motherboard.
6. When the connection is completed, close the control panel and secure it with the retaining screw.
7. Close the front door. Fasten the spring latch.
