Moisture condensation occurs when the temperature of the device is
lower than the ambient temperature.
•
Set cooling units with temperature adjustment to the maximum
surrounding temperature and not lower!
•
Set cooling units with follow-up temperature in such a way that the
interior temperature of the control cabinet is no lower than the
temperature of the surrounding air. Set the temperature limitation to
the maximum surrounding temperature!
•
Only use well-sealed control cabinets so that moisture condensation
cannot 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
(commissioning, 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, as otherwise moisture condensation can
occur. For this reason sufficient circulation must be provided inside the
control cabinet to avoid pockets of heat.
