Warning!
• Risk of electric shock. Switch off the power supply before opening the measuring device.
Never mount or wire the measuring device while it is connected to the power supply. Fail-
ure to comply with this precaution can result in irreparable damage to the electronics.
• Risk of electric shock. Connect the protective earth to the ground terminal on the housing
before the power supply is applied unless special protection measures have been taken
(e.g. galvanically isolated power supply SELV or PELV).
• 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.
Unscrew the connection compartment cover from the transmitter housing.
2.
Feed the power supply cable, the fieldbus cable and the power supply cable for external
termination (optional) cable through the appropriate cable entries.
3.
Perform wiring:

Caution!
– Risk of damage to the fieldbus cable!
Observe the information about shielding and grounding the fieldbus cable
29.
– We recommend that the fieldbus cable not be looped using conventional cable
glands. If even just one measuring device is later replaced, the bus communication
will have to be interrupted.
4.
Screw the cover of the connection compartment back onto the transmitter housing.
