Installing the Wiring
WARNING!
•
Metal shavings or debris in the enclosure can damage electrical equipment
and create a hazardous condition. Where parts, such as conduit plates
require cutting or drilling, first remove the part. If that is not practical, cover
nearby electrical components to protect them from all shavings or debris.
•
Do not connect or disconnect input or output power wiring, or control
wires, when power is applied.
•
Never connect line voltage to drive output Terminals T1, T2, and T3.
•
Do not make any voltage tolerance tests (Hi Pot or Megger) on any part of
the unit. Disconnect motor wires before taking any measurements in the
motor or motor wires.
•
Make sure that power factor correction capacitors are not connected
between the drive and the motor.

•
Properly and individually ground the drive, the motor and cable shields.
