Hello,

I am wondering if I can get some help wiring my VFD to the control box?
The .pdf manual for my particular VFD is attached and I have notated and highlighted my model's info in red.

The cable that I am using between the motor and the VFD is 18/7 outdoor flexible cable.

Thank you !
 
What are the wire colors in the cable? It will make it real simple that way
 
18 ga wire is too small for the motor. You do not want to run motor & control wires in a cable like that. Motor voltage is 240 & control is 10 volts not good in a bundle or same conduit.

Good catch @fixit :encourage:

I missed that one:(

At least 14 ga to the motor from the VFD

Supply the VFD with 12 ga
 
If I understand this correctly, there are control wires between the control box and the VFD, and there are power wires from the service to the VFD and VFD to the motor.
The 18/7 wire is just for the controls. I have some 10/3 for the service power connections and I am reusing the original power cord to the VFD
 
ooops I forgot to attach the manual...
