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.
Connection diagrams
The connections points vary depending on the size of units and the option selected, Power Junction Box
(+H361) or Harmonic Junction Box (+H384). The following figures show the layout and connection points.
Maintain appropriate separation of control and power wires.
