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 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):

NOTICE
Installation error
Damage, e.g. to the cable, or malfunctions are possible
‣Lay cables in such a way that they do not get squashed
e.g. when closing the cabinet door.
‣Plug the display cable only into the RJ45 socket in the
base module. Otherwise, the display will not function.
For a clearer overview, the external power unit has
been omitted from all diagrams.
Use the mounting plate as a drill template. In addition, you will need a pen to mark the drill
holes, as well as a serrated edge rule and a drill.
1. Hold the mounting plate from the outside against the door of the control cabinet.
Choose the point at which you wish to install the display.
2. Make all the markings.
3. Draw lines connecting the markings.
 This will indicate the position of the five drill holes needed.
4. Drill the holes (→  3,  14).
5. Pull the display cable through the hole in the middle, and place the display from the
outside through the 4 holes drilled for this purpose, ensuring that the torx screws have
been unscrewed to the last half turn but are still in place.
6. Connect the display cable to the RJ-45 socket in the base module.
7. Place the mounting plate (a) on the inside over the screws, slide it down (b) and tighten
the screws (c).
 The display is now mounted and ready to use.
