10.3.3 Specific conditions
The X at the end of the documentation number SEV 04 ATEX 01140 X on the label refers to the
following specific conditions:
•
The ambient temperature range is between -15°C to +50°C (see operating conditions in
section
10.3.1 ).
•
The valve island must be used with plugs and cables, which have a conformity evaluation
according to Directive 94/9/EC (ATEX 95) Annex VIII as well as protection class IP65.
1. Recommendation: Use plugs or cables from Norgren, which are certified according to
Directive 94/9/EC (ATEX 95) Annex VIII.
Attention: D-Sub cable for Multipole valve islands, which conforms to all conditions of
Directive 94/9/EC (ATEX 95) Annex VIII, are not available yet. Nevertheless the valve
island can be used according to Directive 99/92/EC (ATEX 137) on the condition defined
under „Valve islands with Multipole and Fieldbus D-Sub connector“.
2. If you are using plugs or cables from another manufacturer, they must have a conformity
evaluation according to Directive 94/9/EC (ATEX 95) Annex VIII. The combination of the
valve island and the plugs/cables used must fulfil the protection class IP65. Use of the
plugs/cables from another manufacturer becomes responsibility of the user.
•
Valve islands with Fieldbus M12 and 7/8“ round connector:
The valve island must be used in a cabinet or protective box or must be protected against
impacts with a protective device (eg. protective fence). This applies above all for the pilot
valves and the plastic parts of the valve island.
•
Valve islands with Multipole and Fieldbus D-Sub connector:
The valve island must be used in a switch cabinet or protective box, which conforms at least
to the protection class IP54. (Attention: Profibus DP with D-Sub connector is not permissible
for ATEX.)
•
Stress peaks:
The voltage may shortly transcended for not more than 40%. This must be prevented
through convenient provisions.
Attention: The permissible voltage range of the valve island is 24V DC +/-10%.
