System Control Drawing 16P577
Do not substitute or modify system components
as this may impair intrinsic safety. For installation,
maintenance, or operation instructions, read
instruction manuals. Do not install equipment
approved only for non-hazardous locationin a
hazardous location. See the identification label for
the intrinsic safety ratingfor your model.

2. The non-intrinsically safe terminals (power rail) must not be connected to any device which uses or
generates more than Um = 250 Vrms or dcunless it has been determined that the voltage has been
adequately isolated.
3. The electrical enclosure ground screw must be connected to a true earth ground using the supplied
ground strap (223547) or by an equivalent10 AWG or larger isolated conductor. Resistance from the
electrical enclosure ground to the trueearth ground shall not exceed 1 ohm.
4. Multiple earthing of components is allowed. Intrinsically safe apparatus provides isolation from earth to
500 Vrms.
Do not operate system with power barrier cover removed.
6. Installation should be in accordance with ANSI/ISA RP12.06.01 “Installation of Intrinsically Safe Systems
for Hazardous (Classified) Locations”and the National Electrical Code® (ANSI/NFPA 70).
7. Installation in Canada should be in accordance with the Canadian Electrical Code, CAS C22.1, Part I,
Appendix F.
8. For ATEX, install per EN 60079–14 and applicable local and national codes.
9. For IECEx install per IEC 60079–14 and applicable local and national codes.
