ergy) must not connected in series. The

special installation regulations (DIN VDE

0165) must be observed.

Pressure transmitters in certain versions are

equipped with a warning label, informing of

measures to be taken to avoid electrostatic

discharge. Keep the contents of the warning

label in mind.

Connection cable

Make sure that the connection cable is speci-

fied for the expected operating temperatures

in your systems. The cable must have an

outer diameter of 5 … 9 mm. Otherwise the

seal effect of the cable connection will not be

ensured.

Cables for intrinsically safe circuits must be

marked with a blue colour and must not be

used for other circuits.
