4.4 Grounding and equipotential bonding
The sensors have no ground connection and no connection for the equipotential bonding.
The cable shield of the sensor cable should be connected to ground according to applicable
installation regulations (IEC 60079-14).
When using junction box type SJB 200 W-Ex, the shield of the sensor cable must be connected to
the shield connector provided. This will ensure sufficient electrostatic grounding and at the
same time prevent unacceptably high equalizing currents.
INFORMATION!
The connections for the intrinsically safe 4...20 mA sensor circuit are galvanically isolated from
both the electrode circuit and the ground and can be considered ground-free (test voltage
500 V
eff
). It is accepted that the electrode circuit can be directly connected to the ground
potential.
