2.2.3 Ambient conditions
The following temperature ranges apply to motors with forced ventilation.
● Permissible temperature range in operation: T = -15 °C to +40 °C
● Permissible temperature range during storage: T = -20 °C to +70 °C
Under conditions other than those specified above (ambient temperature > 40 °C or
installation altitude > 1000 m above sea level), the permissible torques/powers must be
determined from the following table. Ambient temperatures and installation altitudes are
rounded off to 5 °C or 500 m respectively.
