Safety instructions for commissioning

Warning
Intrinsically safe circuits
With intrinsically-safe circuits, use only certified ammeters appropriate for the transmitter.
Specific type examination certificates
If the transmitter is used in a hazardous area, comply with the EC type examination
certificate or the certification valid in your country.
Warning
"Intrinsically safe"
If a non-conforming supply unit is used, the "intrinsically safe" protection type will no longer
be effective and the approval certification will be invalid.
Warning
Fixed installation
Devices to be operated in hazardous areas should be connected with fixed cable installation.
This is not necessary with intrinsically safe devices or devices with "nL" – "limited energy"
protection.
Warning
Tightness
Use cable with a cable diameter of 7 to 12 mm for the IP65 or IP68 protection rating.
