2. Assembly
Festo GDCP-CMXR-C2-HW-EN 1002NH 27
Caution
Damage or malfunctions can occur if the permissible operating
temperature is exceeded!
Please observe the following instructions:
Do not mount the device directly above a source of heat, e.g. a heating appliance,
a current transformer or a high-wattage resistor.
To ensure that heat dissipation can occur, maintain a clearance of at least 50 mm
above and below the modules.
Make sure that the operating temperature within the control cabinet is not higher than
the modules' permissible ambient temperature. Air conditioning has to be provided for
the control cabinet if sufficient cooling cannot be guaranteed by natural heat
dissipation.
When deciding on the configuration within the control cabinet, make certain that the
area around the ventilation slots is not subjected to temperature fluctuations. For
example, do not use air-conditioning units with intermittent operation.
Using air filters
Avoid heavy contamination of the air filters. Clean the air filter regularly.
Recommendation: Install the device into a dust-free, closed control cabinet. If the control
cabinet has vents, these must be equipped with air filters. Make sure that the filter
elements are cleaned or replaced at regular intervals.
2.4 H-rail mounting
Caution
Incorrect fitting causes operative malfunctions.
Prior to fitting the device, check whether the peripheral
modules are correctly mounted and all locking mechanisms
have snapped into place.
To safeguard the modules from slipping or shaking loose due to
vibrations: Attach an end support to the H-rail on both the left
and right sides.
The device is intended for fitting on an H-rail (DIN mounting rail as per EN 60715).
When mounting the H-rail, maintain the max. permissible screw spacing. For reasons of
stability, the screw spacing must not exceed 120 mm, as shown in the graphic.
