Control Circuit Wiring
(1) Control terminal block designations
The control leads must be routed separately from the power supply and motor leads.
They must not be fed through the same cable conduit.

Note: Use twisted-shielded or twisted-pair shielded-lead wires for the control signal. It is
recommended to run signal wiring in a separate steel conduit. The shield wire should only be
connected at the drive.
