1.4 Hazardous Area Interfacing
Correct and safe operation of Elcon HiD 2000 Series calls for expert installation and commissioning as well as
correct operation and meticulous maintenance.
Only those persons conversant with the installation commissioning, operation and maintenance of similar
apparatus and who has the necessary qualifications are allowed to work on HiD 2000 Series.
Make sure installation is carried out observing the safety regulations pertaining to the installation and operation of
electrical system and the directives and guidelines on explosion protection (Hazardous Area equipment should
comply with the descriptive system document).
The installation must be performed by qualified personnel, it must comply with the relevant national/international
standards (e.g. IEC 79-14, CEI 64-2, BS 5345 Pt. 4, DIN VDE 165) and in line with the established installation
rules and recommended practice (e.g. CEI 64-8, ANSI/ISA RP-12.6).
The conformity of hazardous area devices with the related system documentation must always be checked. This
instrumentation IS NOT intended for hazardous area installation, unless it is included in a proper explosion proof
enclosure which conforms to the applicable standards.
For I.S. applications, the maximum limit for AC power supply is 250 Vrms.
For more information on request Elcon will provide the manual “Guide to Intrinsic Safety”, a comprehensive
tutorial about the constraints imposed by the I.S. regulations.
