EC-Type Examination Certificate PTB 99 ATEX 2036X
Applicant Pepperl+Fuchs GmbH, Lilienthalstrasse 200, 68307 Mannheim, Germany
CE marking CE0102
ATEX marking Zone 1: Ex-Hexagon II 2G Ex ia op is IIC T6…T1 Gb
Directive conformity 2014/34/EU
Standards EN 60079-0:2012+A11:2013
EN 60079-11:2012
EN 60079-28:2007
Effective internal capacitance Ci max. 120 nF
Effective internal inductance Li negligibly small
General The apparatus must be operated in accordance with the data provided in the data sheet and this operating instruction. In particular, the maximum rated voltage and the temperature range must be adhered to. The special conditions must be adhered to! The EU-type examination certificate has to be observed.
Ambient temperature The temperature ranges, according to temperature class, are given in the EC-Type Examination Certificate.
Installation, commissioning The associated apparatus must, as a minimum, fulfill the requirements for degree of protection ia and for Groups II or III, as appropriate for the operating conditions. Due to the possible risk of ignition that can occur as a result of faults and/or transient currents in the equipotential bonding system, galvanic isolation in the supply and signal current circuit is preferred. Associated apparatus without galvanic isolation may only be used if the appropriate requirements as set out in IEC 60079-14 are met. The intrinsic safety is only assured in connection with an appropriate related apparatus and according to the proof of intrinsic safety.
Maintenance No modifications must be undertaken on apparatus, which is operated in hazardous areas. Repairs to such apparatus are not permissible.
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.
Degree of protection required when installing connecting components IP20 according to IEC 60529:2001
Other conditions Refer to the relevant EC type examination certificate to see the relationship between the connected circuit type, the maximum permitted ambient temperature and the temperature class as well as effective inner reactances.
