When wiring the sensor to the measuring transducer (preferably blue coloured cable), the approved
inductance and capacitance of the measuring transducer must not be exceeded.
The sensors have a two-pole screw or plug connection or cable tail. Attention does not need to be paid
to polarity.
The integration of the sensors without overvoltage protection into the equipotential bonding is not
required. For integration of the sensors with overvoltage protection into the equipotential bonding, a
PA terminal is provided.

adjustment
No Ex-relevant adjustments are required for operation of the sensors.
III.e
…
putting into service
Before putting into service, all devices must be checked for correct connection and installation. The
electrical supply, including the connected devices, must be checked.
III.f
…
maintenance (servicing and emergency repair)
The sensors are generally maintenance-free. In the case of a defect, this must be returned to the man-
ufacturer or one of its representatives.
The sensors, in particular the probe tip, may be cleaned. Grease-dissolving cleansing agents can be used
to remove any firmly clinging grease or oil residues. Sharp-edged objects are unsuitable for cleaning
since they could damage the sensor.
When performing an insulation test of the intrinsically safe circuit with 500 V under well-controlled con-
ditions, according to EN 60079-25, Clause 12 it is necessary to disconnect sensors with overvoltage pro-
tection since there is no compliance with the requirements for dielectric strength according to
EN 60079-11, Clause 6.3.13. For all other sensors, there is compliance between the intrinsically safe cir-
cuit and the chassis or, if present, other intrinsically safe circuits with 500 V
