NOTICE
Incorrect mounting location in the cabinet, spacing regulations not observed
Possible malfunctions as a result of heat development and interference from neighboring devices
‣
Do not position the device directly above sources of heat. Make sure to observe the temperature
specification.
‣
The components are designed for convection-based cooling. Avoid the buildup of heat and
ensure openings are not covered over, e.g. by cables.
‣
Make sure to keep the specified distance to other devices.
‣
Physically separate the device from frequency converters and high-voltage devices.
‣
Recommended installation direction: horizontal. The specified ambient conditions, and
particularly the ambient temperatures, only apply for horizontal installation.
‣
Vertical orientation is also possible. However, this requires additional fixing clips at the place of
installation to hold the device in position on the DIN rail.
‣
Recommended installation of the power unit for CM444R and CM448R: to the left of the device.
The following minimum spacing specifications must be observed:
• Distance at the side to other devices including power units and distance to control cabinet wall:
at least 20 mm (0.79 inch)
• Distance above and below the device and depth distance (to control cabinet door or other devices
installed there):
at least 50 mm (1.97 inch)
