Connect AC Input Wire (1-Phase or
3-Phase to Power Terminal Strip

(This step requires installation by quali ed personnel)

Locate the power terminal strip. Check the AC voltage
rating shown on the Inverter nameplate with the AC
incoming voltage.

Caution:
Applying voltage
higher than the
rated VCM AC
input voltage will
damage the drive
and could cause
personal injury.

Connect Motor Leads to Terminal Strip

Check the motor leads to insure they are wired to
match the 230 Volt or 460 Volt output as shown on
the VCM inverter nameplate.

Caution: Applying higher than rated voltage will
damage the motor.
