2.1 Safety Measures for Use in Hazardous Areas
2.1.1 Starting Up and Starting Up after Service
• The DMA 35
N
is suitable for use in hazardous areas only if the instrument is
labelled with the ATEX registration number (see Appendix D).
• The intrinsically safe DMA 35
N
can be used according to ATEX marking II 2
G EEx ib IIC T5. All instructions given in the certificate of conformity have to be
followed (see Appendix D).
• By labelling the intrinsically safe DMA 35
N
with the type plate according to ATEX,
Anton Paar GmbH confirms that the instrument conforms with all documents
submitted for receiving the certificate of conformity. Therefore, do not subject the
intrinsically safe DMA 35
N
to alterations of any kind.
• Repaired instruments may be operated only if the repair was carried out by
Anton Paar GmbH. The type plate according to ATEX still confirms that the
intrinsically safe DMA 35
N
conforms with all documents submitted for receiving
the certificate of conformity.
2.1.2 Battery Exchange
• Use only batteries of the same type and in the same level of charge.
• When exchanging the batteries, always check that the small parting plate is
inside the battery compartment chamber and properly fixed.
• After the battery exchange (outside the hazardous area), close the battery cover
and fix it with the Phillips screw.
• Check the function of the instrument: Turn the instrument on and check the
display.
2.1.3 Infrared/RS 232 Interface Port
• Never use the infrared/RS 232 interface port in hazardous areas.
