Note:
Derate the output current by 1% for each 100 m (328 ft) to install the drive in altitudes between
1000 m to 4000 m (3281 ft to 13123 ft).
It is not necessary to derate the rated voltage in these conditions:
• When you install the drive at 2000 m (6562 ft) or lower
• When you install the drive between 2000 m to 4000 m (6562 ft to 13123 ft) and ground the
neutral point on the power supply.
Contact Yaskawa or your nearest sales representative if you will not ground the neutral point.
