Section 2 Product Description
In I.S. applications, modules with I.S. Interfaces MUST be mounted right most
of the I/O station or as a separate group.
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 field devices with the related system documentation must always
be checked.
When using modules with I.S. Interfaces in non I.S. applications, the I.S.
modules can be placed in any position following the same rules as non I.S.
modules.
