◆ Altitude Derating
Install the drive in a location that with 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 m to 3000
m (3281 ft. to 9843 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 m to 3000 m (6562 ft. to 9843 ft.) and grounding the neutral point on the
power supply.
Contact Yaskawa or your nearest sales representative when the drive is not grounded with the neutral network.
