Important!
The flowmeter system satisfies EN 61326 and the NAMUR-Recommendations NE 21 „Electromagnetic
Compatibility of Equipment in Processes and Laboratories”. To satisfy these recommendations a new signal
cable was developed with a second, separate outer shield. The outer shield to connected to terminal SE on
the flowmeter primary and the terminal on the converter.
If the flowmeter primary is an older model (10D1422, 10DI1425, 10DS3111, DS4_, DS2_) and does not
have a SE-terminal, then the outer shield is connected only at one end to the converter.
