NOTICE
Pointed or sharp tools
The use of unsuitable tools can cause scratches on the housing or damage to the seal, andtherefore negatively affect the leak-tightness of the housing!
‣ Do not use any sharp or pointed objects, e.g. a knife, to open the housing.
‣ Only use a suitable Phillips screwdriver.

Module installation

9.2.1

Bus termination (only module 485DP and 485MB)

If you wish to use the module's internal resistor to terminate the bus, you must configure thehardware prior to installing the module.

8Endress+Hauser

EA01447C

9.2.2

Installation conditions‣ Prior to installation:
Ascertain the extension options for the device.
 Use Configurator on the product page in question, e.g.: www.products.endress.com/
cm442 or .../cm444R .../CSF48 or ...
• You can use only one fieldbus. Example: You have had HART active up to now. Afterinstalling module 485DP, activate PROFIBUS DP (via activation code). HART is thendeactivated!
• In the case of CM442/442R, any existing current outputs are disabled with theinstallation of the 485DP or 485MB module!
• In the case of CM444/444R, CM448/448R, CSFxx or CA80XX, you can additionallyhave a maximum of 2 current outputs.
9.2.3

Module installation (using the example of 485DP and 485MB)

The procedure for installing the module in the electronics box is the same for all
specified devices. In the diagrams in this section, however, only the Liquiline CM44x(field housing) is shown.
You must install the module 485DP or 485MB in slot 2. With a CM442/442R, all availableslots are assigned once this is done. With all other devices, additional slots are available foryou to install other electronics modules.
1.

If another module is already installed in slot 2:
Remove electronics module. Use the removal aids on the module to pull it out.

Endress+Hauser

9EA01447C

2.

If only the base module is present:
Remove module end cover.
3.

Insert the fieldbus module into the guides for slot 2 until it snaps into place.
4.

Insert the 6 mm dummy cover after the module. The dummy cover is included in thescope of delivery of this module kit.

10Endress+Hauser

EA01447C

5.

Finally, insert the module cover again.
 The fieldbus module is the last module in the diagram. If you wish to use additional
modules, insert the end cover after the last module.

9.3

Electrical connection

LWARNING
Device is live!
Incorrect connection may result in injury or death!
‣ The electrical connection may be performed only by an electrical technician.
‣ The electrical technician must have read and understood these Operating Instructions andmust follow the instructions contained therein.
‣ Prior to commencing connection work, ensure that no voltage is present on any cable.
LWARNING
Module not covered
No shock protection. Danger of electric shock!
‣ If you are modifying or extending your hardware, always fill the slots from left to right(CM44x) or from top to bottom (CSFXXxx). Do not leave any gaps.
‣ If not all slots are occupied, always insert a dummy cover or end cover after the last module(for CM44x) or below the last module (for CSFXXxx). This ensures the that unit is shockprotected.
‣ Ensure shock protection is guaranteed, particularly in the case of relay modules (2R, 4R,AOR).
