VGN Controller Incoming Power
Wiring Instructions
Incoming Power (hard wire connections)
The VGN controller will function on 120, 208, 240, or
480V single-phase 50/60 Hz AC. Remove the metal
cover located on the right side of the VGN controller to
access the terminal strip for incoming power (reference
Wire Diagram for details on terminal strip landing
points). Once the wiring is complete reinstall the metal
cover. Each VGN controller will draw a maximum of
2amps.

NOTE: There is only one on the fly unoccupied nozzle
velocity adjustment for the entire VGN control system
regardless of the number of fans; one BMS signal
commands all the nozzles to the same outlet velocity.

Outlet Velocity: On the Fly Unoccupied
Adjustment
This feature is not required for system
operation. This feature allows the user to adjust the
nozzle outlet velocity remotely while the fan is running
with the use of a 0-10 VDC signal sent from the BMS
to the VGN controller. Connect the BMS directly to the
proper input (see below) on the Carel PLC unit and
COM on the terminal strip.
Wire Landing Points
• Single Fan Entire System: B5 on Carel PLC and COM
on the terminal strip
• Multifan Entire System: U5 on Carel PLC and GND
on the Carel PLC
