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):

5.2 Mounting the measuring device
5.2.1 DIN rail mounting
The mounting procedure is the same for all Liquiline devices. The example shows a
CM448R.
1. In the order configuration, the securing clips are "tightened" to secure the DIN rail.
Release the securing clips by pulling them downwards.

2. Attach the device from the top to the DIN rail (a) and then press it down to secure it
(b).


3. Slide the securing clips upwards until they click, thereby securing the device to the
DIN rail.

4. CM444R and CM448R only
Mount the external power unit in the same way.
5.2.2 Wall mounting
Mounting material (screws, dowels) are not included in the scope of delivery and must
be provided by the customer.
CM444R and CM448R: The external power unit can be mounted on a DIN rail only.
Use the back of the housing to mark the mounting holes. (→  8,  17)
1. Drill the required holes and place dowels in them if necessary.
2. Screw the housing onto the wall.
