STEP 3: Wiring the M400 VFD Device to Emerson Controllers
Wire the device as shown below:
COM wiring is the REVERSE polarity of Site Supervisor.
•+ On the Com port goes to - on the VFD.
•- On the Com port goes to the + on the VFD.
• Do NOT connect shield to any terminal on the controller or VFD. Connect shield directly to Earth Chassis at the
controller; clip and insulate shield at VFD end of cable.
• If VFD is the last device at the end of Com segment, terminate with 150 ohms between terminals 2 and 3.
