Instructions Specific To Hazardous Area Installations (Reference European Atex Directive 94/9/Ec, Annex Ii, 1/0/6) - Siemens ST-H Series Operation Manual

Instructions specific to hazardous area installations
(Reference European ATEX Directive 94/9/EC,
The following instructions apply to equipment covered by certificate number BAS
99ATEX2298X.
1. The equipment may be used with flammable gases and vapors with the Apparatus Group
II and with Temperature class T5.
2. The equipment is certified for use in an ambient temperature range of -20 °C to +60 °C
3. The equipment has not been assessed as a safety related device as referred to by EC
Directive 94/9/EC Annex II, clause 1.5.
4. The certificate has a 'X' suffix, which indicates that special conditions of installation and
use apply. Those installing or inspecting this equipment must have access to the contents
of the certificate.
5. The transducer has no internal fuse or any other components which will guarantee its
suitability for connection to a prospective short circuit current of 4000A. The transducer
must be supplied from apparatus suitable for connection to a supply having a prospective
short circuit not exceeding 4000A. This condition is met by Siemens Milltronics
transceivers.
6. Installation and inspection of this equipment shall be carried out by suitably trained
personnel in accordance to the applicable code of practice (EN 60079-14 and EN 60079-17
within Europe).
7. Repair of this equipment shall be carried out by suitably trained personnel in accordance
with the applicable code of practice (e.g. EN60079-19 within Europe).
8. Components to be incorporated into or used as replacements in the equipment shall be
fitted by suitably trained personnel in accordance with the manufacturer's
documentation.
9. The certification of this equipment relies upon the following materials used in its
construction:
• Norton Performance Plastics Chemgrip bonding compound
• Dupont Tefzel 210 housing material
• Elf Atochem Kynar Flex 2820 housing material
• Dow-Corning 3-4207 encapsulant
• Cotronics Durapot 861-F3 encapsulant
• Cotronics Durapot 864 encapsulant
If the equipment is likely to come into contact with aggressive substances, such as solvents
that may affect polymeric materials, it is the responsibility of the user to take suitable
precautions to prevent the equipment from being adversely affected. It is important to perform
routine inspections and establish from the materials data sheet that the transducer is resistant
to chemicals used in the application.
