CE marking 0102
Ex-identification ¬ II 1G Ex ia IIC T6 Ga
EC-Type Examination Certificate PTB 00 ATEX 2032 X
Appropriate type
NJ 2-V3-N ...
Effective internal capacitance C
i
≤ 40 nF ; a cable length of 10 m is considered.
Effective internal inductance L
i
≤ 50 µH ; a cable length of 10 m is considered.
Cable length Dangerous electrostatic charges on the fixed connection cable must be taken into
account for lengths equal to and exceeding the following values:
Explosion group IIC 14.8 cm
General The apparatus has to be operated according to the appropriate data in the data
sheet and in this instruction manual. The EC-Type Examination Certificate has to
be observed. The special conditions must be adhered to!
Highest permissible ambient temperature The temperature ranges, according to temperature class, are given in the EC-Type
Examination Certificate. Note: Use the temperature table for category 1 !!! The 20
% reduction in accordance with EN 1127-1:2007 has already been accounted for in
the temperature table for category 1.
Installation, Comissioning 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 transient
currents in the equipotential bonding system, galvanic isolation of the power supply
and signal circuit is preferable. Associated apparatus without electrical isolation
must only be used if the appropriate requirements of IEC 60079-14 are met.
Maintenance No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
Specific conditions
Protection from mechanical danger
When used in the temperature range below -20 °C the sensor should be protected
from knocks by the provision of an additional housing.
Electrostatic charging
When used in group IIC non-permissible electrostatic charges should be avoided
on the plastic housing parts.
