Coolant temperature
When setting the coolant inlet temperature
within a range of 10 ... 40°C (for derating see
Chapter 8.5 “Derating in case of deviating
ambient conditions” on page 58
) observe the
ambient temperature and the existing relative
air humidity. To avoid condensation, the coolant
inlet temperature must be above the dew point
temperature . The following figure shows the
dependency of dew point temperature of relative
air humidity and air temperature.
Fig. 4: Dew point temperature depends from
ambient temperature and relative air humidity
Example
①
Saturation 15.3 °C at ambient tem-
perature of 25°C and relative air
humidity of 55%
Remark:
To avoid condensation of the motors,
the coolant inlet temperature must be above the
dew point temperature .
