Installation
•
Do not connect the non-intrinsically safe terminals
(power rail) to any device that uses or generates
more than Um=250 Vrms or DC, unless the voltage
is adequately isolated.
•
Installation in the United States must meet the
requirements of the National Electrical Code
(ANSI/NFPA 70) and Recommended Practice for
Wiring Methods for Hazardous (Classified) Loca-
tions Instrumentation Part 1: Intrinsic Safety
(ANSI/ISA-RP12.06.01).
•
Installation in Canada must meet the requirements
of the Canadian Electrical Code, CSA C22.1, Part I,
Appendix F.
•
For ATEX, install according to EN 60079-14 and
applicable local codes and regulations.
•
For IECEx, install according to IEC 60079-14 and
applicable local codes and regulations.
•
Multiple earthing of components is allowed only if a
high integrity equipotential system is realized
between the points of bonding.
•
The G-Barrier does not provide galvanic isolation
from earth or between non-intrinsically safe and
intrinsically safe connections
•
Install wiring associated with intrinsically safe chan-
nels A, B, C as separate intrinsically safe circuits
according to the applicable installation codes.
•
The specified Ca, Co, La, Lo parameters take the
effects of combined external capacitance and induc-
tance into account. No further reduction in the spec-
ified Ca, Co, La, Lo parameters is required.
•
Do not disassemble.
Do not substitute or modify system components as
this may impair intrinsic safety. Do not install equip-
ment approved only for a non-hazardous location in a
hazardous location.
