Earth the housing, through the process connection, against electromagnetic fields and
electrostatic discharge.
Operate the pressure transmitter with a shielded cable and earth the shield at least on
one side of the cable, if the cable is longer than 30m (2-wire) or 3m (3-wire), or if it is
run outside of the building.
Ingress protection per IEC 60529 (The ingress protection classes specified only apply
while the pressure transmitter is connected with female connectors that provide the
corresponding ingress protection).
Please observe the following when selecting
the connector:
Temperature range T > T transmitter + 20 K
Ingress protection
≥ IP 54 (explosion protection)
Conductor cross-section
≥ A 0.25 mm

the cable:
when selecting the cable length, ensure that it is 3x longer than the cable length
required, so that the cable can be pulled to different locations.
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.
Please make sure that the ends of cables with flying leads do not allow any ingress of
moisture.
