6.1 Mechanical Data
Figure 6-1
Humidity range
Relative air humidity for the SINAMICS G120 Power Module is ≤ 95 % non-condensing.
In areas of high relative humidity, measures should be taken to ensure that condensation
does not form within or around the SINAMICS G120 Power Module. Anti-condensation
heaters are commonly used to prevent the formation of condensation.
Altitude
If the SINAMICS G120 Power Module is to be installed at an altitude greater than 1000 m
(3280 ft) derating will be required. The figure below shows the derating required in
accordance with altitude.
