Degrees of motor protection IP55 (IEC 60034-5);
Altitude shall not exceed 1000m above sea-level (IEC 60034-1);
Allowed air temperature between -20 ºC and 40 ºC (IEC 60034-1);
Permitted relative humidity:
• -20 ºC ≤ T ≤ 20 ºC：100 %
• 20 ºC < T ≤ 30 ºC：95 %
• 30 ºC < T ≤ 40 ºC：55 %
For high than 1000 m above sea level, the specified motor output muster coolant temperatures and / or site altitudes higher be reduced by using the factor kHT. The results in an admissible output (Padm) of the motor: Padm = Prated • kHT
