does not spray accumulated condensation water onto the devices in the
control cabinet. Mount the air duct in the control cabinet accordingly.

Moisture condensation occurs when the temperature of the device is lower
than the ambient temperature.
● Set cooling units with temperature adjustment to the maximum sur‐
rounding temperature and not lower!
● Set cooling units with follow-up temperature in such a way that the inte‐
rior temperature of the control cabinet is not 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 cabi‐
net.
● 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. For this reason, sufficient circulation must
be provided inside the control cabinet.
