ATEX 1G
Instruction Manual electrical apparatus for hazardous areas
Device category 1G
for use in hazardous areas with gas, vapour and mist
EC-Type Examination Certificate PTB 00 ATEX 2048 X
CE marking 0102
ATEX marking ¬ II 1G Ex ia IIC T6…T1 Ga
Directive conformity 94/9/EG
Standards EN 60079-0:2012, EN 60079-11:2012, EN 60079-26:2007
Ignition protection "Intrinsic safety"
Use is restricted to the following stated conditions
Appropriate type NJ 5-18GM-N...
Effective internal capacitance Ci ≤ 70 nF ; a cable length of 10 m is considered.
Effective internal inductance Li ≤ 50 µH ; a cable length of 10 m is considered.
Ge n e r a l 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!
Directive 94/9/EG and hence also EC-Type Examination Certificates apply in general
only to the use of electrical apparatus under atmospheric conditions.
The use in ambient temperatures of > 60 °C was tested with regard to hot surfaces
by the mentioned certification authority.
If the equipment is not used under atmospheric conditions, a reduction of the permis-
sible minimum ignition energies may have to be taken into consideration.
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, commissioning 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 appro-
priate related apparatus and according to the proof of intrinsic safety. The associated
apparatus must satisfy the requirements of category "ia" and have electrical isolation
between the power supply and signal circuits.
The sensor must be protected from strong electromagnetic fields.
Maintenance No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
Special 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 charge Electrostatic charges must be avoided on the mechanical housing components.
Dangerous electrostatic charges on the mechanical housing components can be
avoided by incorporating these in the equipotential bonding.
