High Altitude
If the AC motor drive is installed at an altitude 0–1000 m, follow normal operation
restriction. For altitudes of 1000–2000 m, decrease 1% of the drive rated current or
lower 0.5°C of temperature for every 100 m increase in altitude. The maximum altitude
for Corner Grounded is 2,000 m. If installing at an altitude higher than 2000 m is
required, contact Delta for more information.
