≤ 150 nF ; a cable length of 10 m is considered.
≤ 150 µH ; a cable length of 10 m is considered.
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 maximum surface temperature of the housing is given in the EC-Type
Examination Certificate.
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 at least the requirements of category ia
IIB or iaD. Because of the possibility of the danger of ignition, which can arise
due to faults and/or transient currents in the equipotential bonding system, gal-
vanic isolation in the power supply and signal circuits is preferable. Associated
apparatus without electrical isolation must only be used if the appropriate
requirements of IEC 60079-14 are met.
The intrinsically safe circuit has to be protected against influences due to light-
ning.
When used in the isolating wall between Zone 20 and Zone 21 or Zone 21 und
Zone 22 the sensor must not be exposed to any mechanical danger and must
be sealed in such a way, that the protective function of the isolating wall is not
impaired. The applicable directives and standards must be observed.
No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
The connection cables are to be laid in accordance with EN 50281-1-2 and must
not normally be subjected to chaffing during use.
