≤ 150 nF ; a cable length of 10 m is considered.
≤ 150 µH ; a cable length of 10 m is considered.
Dangerous electrostatic charges on the fixed connection cable must be taken
into account for lengths equal to and exceeding the following values:
30 cm
The apparatus has to be operated according to the appropriate data in the data
sheet and in this instruction manual. The EU prototype test certificate must be
observed. The special conditions must be adhered to!
The temperature ranges, according to temperature class, are given in the EU
prototype test certificate. Note: Use the temperature table for category 1 !!! The
20 % reduction in accordance with EN 1127-1 has already been applied to the
temperature table for category 1.
Laws and/or regulations and standards governing the use or intended usage
goal must be observed.
The intrinsic safety is only assured in connection with an appropriate related
apparatus and according to the proof of intrinsic safety.
The associated apparatus must satisfy the requirements of category ia.
Due to the possible danger of ignition, which can arise due to faults and/or tran-
sient currents in the equipotential bonding system, galvanic isolation of the
power supply and signal circuit is preferable. Associated apparatus without elec-
trical isolation must only be used if the appropriate requirements of IEC 60079-
14 are met.
No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
The sensor must not be mechanically damaged.
When used in the temperature range below -20°C the sensor should be pro-
tected from knocks by the provision of an additional housing.
