5.4 Air conditioning and ventilation
The module is equipped with ventilation holes for heat dissipation. Make sure
that the ventilation holes are not covered.
The CP 263/x is also equipped with an internal ventilator. For further informa-
tion on the ventilator, please consult the maintenance section of this manual.
CAUTION!
High temperatures may destroy the module!
● The operating temperature inside the control cabinet must not be higher
than the permissible ambient temperature of the module. If this cannot be
guaranteed through natural heat dissipation, an air conditioning of the con-
trol cabinet must be provided.
Information
There must be a free space of at least 30 mm above and below the modules
to guarantee head dissipation.
5.4.1 Use of air filters
To ensure that the contamination does not exceed contamination level 2 (ac-
cording to EN 61131-2), the device must be installed in a dustproof, closed
control cabinet. Fan openings of the control cabinet must be equipped with air
filters. The filter elements must be cleaned or replaced regularly.
Information
Contamination level 2, description according to standard:
"The occurring contamination is generally not conductive. However, tempo-
rary conductivity must be expected due to condensation."
