Derating data
The units have an integrated temperature monitoring function. A fan included as standard
supports the power unit cooling. The fan is switched on and off by means of a temperature
control, which prevents it from running unnecessarily. The permissible ambient temperature
is from 0 °C to 40 °C. For temperatures between 40 °C and 50 °C, the power must be
reduced according to the following formula:
● P = [1 − 0.025 x (T − 40 °C)] x P
The installation altitude above sea level can be up to 2000 m. The power must be reduced
for altitudes above 1000 m (derating). In this case, the derating is 1.5 % per 100 m.
