Install the drive in a location that has an altitude of 1000 m (3281 ft) or lower.

Derate the output current by 1% for each 100 m (328 ft) to install the drive in altitudes between 1000 to 4000 m (3281 to 13123 ft).

It is not necessary to derate the rated voltage in these conditions:

  • Installing the drive at 2000 m (6562 ft) or lower

  • Installing the drive between 2000 to 4000 m (6562 to 13123 ft) and grounding the neutral point on the power supply.

    If you do not ground the drive with a neutral network, contact Yaskawa or your nearest sales representative.
