Warning! 
• Risk of electric shock. Switch off the power supply before opening the device. Do not install or 

wire the device while it is connected to the power supply. Failure to comply with this precaution 
can result in irreparable damage to parts of the electronics.

• Risk of electric shock. Connect the protective earth to the ground terminal on the housing before 

the power supply is applied (not required for galvanically isolated power supply).

• Compare the specifications on the nameplate with the local supply voltage and frequency. The 

national regulations governing the installation of electrical equipment also apply.

1.

Remove the cover (a) from the connection compartment.

2.

Route the power supply cable (b) and fieldbus cable (d) through the appropriate cable entries.

!

Note! 

The measuring devices can also be supplied with the option of a ready-mounted fieldbus 
connector. Further information: 

3.

Perform wiring: wiring diagram (aluminum housing, stainless steel housing or wall-mount 
housing)

Caution! 

– Risk of damaging the fieldbus cable!

If the shielding of the cable is grounded at more than one point in systems without additional 
potential equalization, power supply frequency equalization currents can occur that damage 
the cable or the shielding.
In such cases the shielding of the cable is to be grounded on only one side, i.e. it must not 
be connected to the ground terminal of the housing. The shield that is not connected should 
be insulated!

– We recommend that the fieldbus cable not be looped using conventional cable glands. If you 

later replace even just one measuring device, the bus communication will have to be 
interrupted.

!

Note! 

– The terminals for the PROFIBUS PA connection (26/27) have integrated reverse polarity 

protection. This ensures correct signal transmission via the fieldbus even if lines are mixed 
up.

– Conductor cross-section: max. 2.5 mm

4.

 Seal the connection compartment again.
