Caution
The air guidance and arrangement of the cooling equipment must be chosen in such a way
as to prevent condensation from forming.
If necessary, cabinet enclosure heating may have to be installed.
If air conditioners are used, the relative air humidity of the expelled air increases as the air in
the air conditioner cools and may exceed the dew point. If the relative humidity of the air
entering the SINAMICS equipment is over 80% for an extended period of time, the insulation
in the equipment may fail to function properly due to electrochemical reactions (see System
Overview). Using air baffle plates, for example, you must ensure that the cold air expelled
from the air conditioner mixes with warm air in the cabinet before it enters the equipment.
This reduces the relative air humidity to uncritical values.
7.7.3 Power loss of components in rated operation
The following table shows the power loss for components with internal cooling.
The characteristic values apply for the following conditions:
• Line voltage for Line Modules 400 V
• Pulse frequency of the Motor Modules 4 kHz
• Rated pulse frequency of the Active Line Modules 8 kHz
• Operation of components with rated power
