System manual CECX / CPU module
14.6
Air conditioning and ventilation
Ventilation holes for dissipating the heat are placed at the top and under-
side of the module. If the permissible ambient temperature is not exceeded,
no external fan will be needed. Make sure that the ventilation holes are not
covered.
!
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 condi-
tioning of the control cabinet must be provided.
When installed in a control cabinet attention must be given that the
area around the temperature inputs is not exposed to any temperature
changes (e.g. no air conditioners with intermittent operating hours).
Information
To guarantee the dissipation of heat, it is advisable to leave a free space of
at least 30 mm above and below the modules
14.6.1 Use of air filters
To ensure that the contamination does not exceed contamination level 2
(according to EN 61131-2), the control 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."
