Specific conditions for safe use in explosive atmosphere:
External earthing connection shall be established by end-user via pressure
„
connection minimum 4 mm² required. External earthing connection shall be
corrosion resist and locked against rotation.
Warning
Suitable connector minimum IP 54 shall be provided by end-user (In the
„
end-use application the degree of protection min IP54 shall be maintained).
If applicable the connector shall be in accordance with EN 60079-0:2006
and EN 60079-15:2005
Cable provided by end-user shall be suitable for the ambient temperature.
„
If long connecting cables (greater than 30m) or leads outside buildings are to be used,
„
use screened leads. Note that with plug connectors, no connection between cable
screen and housing is possible. Take care, therefore, for installations in explosion
hazard areas, that equipotential bonding is used.
For instruments with cable outputs, the cable is always shielded. Depending upon the
design (ordered version) the screen may or may not be connected with the enclosure.
Also provide for equipotential bonding here, if necessary.
Ensure that the cable diameter you select fits to the cable gland of the connector
„
Ensure that the cable gland of the mounted connector is positioned correctly and
that the sealings are available and undamaged. Tighten the threaded connection and
check the correct position of the sealings in order to ensure the ingress protection
Cover flying leads with fine wires by an end splice (cable preparation).
„
Please make sure that the ends of cables with flying leads do not allow any ingress of
„
moisture.
The transducer must be connected and operated in accordance with the approriate
„
regulations. Take care to ensure that the electrical connection (e.g. M12 connector) is
correctly made (fully sealed).
