Requirements for control cabinets
with fan
Risk of damage by unclean air in the control
cabinet!
Operating a control cabinet with a fan, but without the corresponding filters,
can damage the devices or cause malfunction.
● Install filters at the air intake opening of the control cabinet so that
unclean air cannot get into the control cabinet.
● Service the filters at regular intervals according to the dust loading in the
environment.
● Only replace the filters when the fan has been switched off, because
otherwise the fan sucks in the dirt coming off the filter and the dirt gets
into the control cabinet.
