In hazardous areas you should take note of the appropriate

The connection must be carried out by trained and

authorised personnel only!

connecting the measuring probe Pt100 to the apparatus. It

is also possible to use three-wire cables, but the

measurement accuracy will deteriorate due to the

asymmetry of the resistances of wires, and due to the

incertainty of contact resistances.

For connecting the loop-feeding, a two-wire, twisted pair,

shielded cable must be used.

For connecting the limit-value outputs, two-wire, twisted pair

cable with 500 V insulation may be used.
