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.
