NOTICE
Damage to the component through condensation
Condensation on the components can cause them to fail.
• Select the air circuit and arrangement of the cooling equipment in such a way that no
condensation can form on the components.
• If required, an anti-condensation heater must be installed in the cabinet.
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 components is over 80% for an extended period of time, it can be
assumed that the insulation of the components will fail as a result of electrochemical
reactions (see System overview (Page 35)). 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 components. This reduces the relative air humidity to uncritical values.
