Natural cooling
•
Forced ventilation
•
Water cooling
•
Temperature class 155 °C (F) for a winding overtemperature of
ΔT = 100 K at an ambient temperature of +40 °C (naturally cooled,
force-ventilated) or a coolant temperature of +30 °C (water-cooled)
IVIC: C
-15° to +40° C, derating at higher temperatures
≤ 1000 m above sea level, otherwise power derating
For installation altitudes of more than 2000 m above sea level,
additional reduction of the voltage load of the motors (see ambient
conditions).
