Control Signal Wiring

See the Invertek Quick Start Guide that comes packaged with the VFD for VFD wiring instructions. Further
information is also available in the Invertek ODE-3 IP66 Outdoor User Guide (MV2493). It can be viewed online
at www.choretime.com/documents, Manuals, Ventilation, Fans & Shutters, 57-Inch Endura Fans, MV2493.
For variable speed fan control connect the 10-0 vdc analog signal from the main control to VFD terminals 6
(positive) and 7. The Fan will run full speed with an analog signal of 0 vdc and slow down to a stop as the signal
is increased to 10 vdc.
For optional Fan Backup Control, in case of main control failure, connect a backup relay to terminals 1 and 4. The
Fan will run full speed when the backup relay contacts are closed.
The jumper from terminals 1 to 2 is required for Fan operation.
Backup Box Relay (Optional)
