If the AC motor drive operats at the rated current, the ambient temperature needs to be
between -10 40°C. If the temperature is above 40°C, decrease 2% of the rated current
–
for every 1°C increase in temperature. The maximum allowable temperature is 60°C.
If the AC motor drive operats at the rated current, the ambient temperature needs to be
between -10 50°C. If the temperature is above 50°C, decrease 2% of the rated current
–
for every 1°C increase in temperature. The maximum allowable temperature is 60°C.
If the AC motor drive is installed at an altitude of 0
restrictions. For altitudes of 1000
lower the temperature by 0.5°C for every 100 m increase in altitude. The maximum
altitude for corner grounding is 2000 m. If installing at an altitude higher than 2000 m is
required, contact Delta for more information.
