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 99 ATEX 2219 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 SJ3,5-...-N...

Effective internal capacitance Ci ≤ 50 nF ; a cable length of 10 m is considered.

Effective internal inductance Li ≤ 250 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!

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 appropriate related appara-

tus 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.

Install the device in such a way that the resin surface is not exposed to mechanical

hazards.

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.

Maximum housing surface temperature The maximum surface temperature of the housing is given in the EC-Type Examina-

tion Certificate.

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 appropriate related appara-

tus 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, galvanic 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 lightning.

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 appli-

cable directives and standards must be observed.

Maintenance No changes can be made to apparatus, which are operated in hazardous areas.

Repairs to these apparatus are not possible.

Special conditions

Electrostatic charge The connection cables are to be laid in accordance with EN 50281-1-2 and must not

normally be subjected to chaffing during use.
