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 the electronics.
• Risk of electric shock. Connect the protective ground 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. Remove the cover of the connection compartment (a) from the transmitter housing.

Caution!
– Risk of damaging the fieldbus cable!
Observe the information about shielding and grounding the fieldbus cable (→ ä 20).
