●
Position the cooling unit in such a way that the blower of the cooling unit
does not spray accumulated condensation water onto the devices in the
control cabinet. Mount the air duct in the control cabinet accordingly.

Arranging the Cooling Units
Avoiding Moisture Condensation
Moisture condensation occurs when the temperature of the device is lower than
the ambient temperature.
●
Set cooling units with temperature adjustment to the maximum surround‐
ing temperature and not lower!
●
Set cooling units with follow-up temperature in such a way that the interior
temperature of the control cabinet is not lower than the temperature of the
surrounding air. Set the temperature limitation to the maximum surround‐
ing temperature!
●
Only use well-sealed control cabinets so that moisture condensation can‐
not arise as a result of warm and moist external air entering the cabinet.
●
In the event that control cabinets are operated with the doors open (com‐
missioning, servicing etc.), it is essential to ensure that after the doors are
closed the drive controllers cannot at any time be cooler than the air in the
control cabinet. For this reason, sufficient circulation must be provided
inside the control cabinet.
