When the AC motor drive is operating at the rated current and the ambient temperature
has to be between -10°C– +40°C. When the temperature is over 40°C, for every
increase by 1°C, decrease 2% of the rated current. The maximum allowable
temperature is 60°C.
When the AC motor drive is operating at the rated current and the ambient temperature
has to be between -10°C– +50°C. When the temperature is over 50°C, for every
increase by 1°C, decrease 2% of the rated current. The maximum allowable
temperature is 60°C.
If AC motor drive is installed at altitude 0–1000m, follow normal operation restriction. If
it is install at altitude 1000–2000m, decrease 1% of rated current or lower 0.5°C of
temperature for every 100m increase in altitude. Maximum altitude for Corner
Grounded is 2000m. Contact Delta for more information, if you need to use this motor
drive at an altitude of 2000m or higher.
