Nonincendive Field Wiring Concept:
The Nonincendive Field Wiring concept allows for the interconnection of nonincendive field
wiring apparatus using any of the wiring methods permitted for unclassified locations.
Vmax >= Voc or Vt, Ca >= Ci +Ccable, La >= Li + Lcable"
Installation Notes For FISCO and Entity Concepts:
1. The Intrinsic Safety Entity concept allows the interconnection of FM / UL / CSA-
approved intrinsically safe devices (Div. 1 or Zone 0 or Zone1), with entity
parameters not specifically examined in combination as a system when: Uo or Voc
or Vt  Vmax, Io or Isc or It  Imax, Po  Pi.
Ca or Co  Ci + Ccable, La or Lo  Li + Lcable, Po  Pi.
2. The Intrinsic Safety FISCO concept allows the interconnection of FM / UL / CSA-
approved intrinsically safe devices with FISCO parameters not specifically
examined in combination as a system when:
Uo or Voc or Vt  Vmax, Io or Isc or It  Imax, Po  Pi.
3. Control equipment connected to the Associated Apparatus must not use or generate
more than 250 Vrms or Vdc.
4. Intrinsically Safe Installation should be in accordance with ANSI/ISA RP12.6.01
(except chapter 5 for FISCO Installations) "Installation of Intrinsically Safe Systems
for Hazardous (Classified) Locations" and the National Electrical Code®
(ANSI/NFPA 70) Sections 504 and 505.
5. The configuration of associated Apparatus must be FM Approvals or UL / CSA
Approved under the associated concept.
6. Associated Apparatus manufacturer's installation drawing must be followed when
installing this equipment.
7. The 5350B is approved for Class I, Zone 0, applications. If connecting AEx[ib]
associated Apparatus or AEx ib I.S. Apparatus to the 5350B the I.S. circuit is only
suitable for Class I, Zone 1, or Class I, Zone 2, and is not suitable for Class I, Zone
0 or Class I, Division 1, Hazardous (Classified) Locations".
8. No revision to drawing without prior FM / UL / CSA Approval.
9. Simple Apparatus is defined as a device that neither generates nor stores more than
1.5 V, 0.1 A or 25 mW.
10. The termination must be NRTL-approved, and the resistor must be infallible.
11. Warning:
For applications in Div. 2 or Zone 2 (Classified Locations) Explosion hazard: Except
for nonincendive field circuits, do not disconnect the apparatus unless the area is
known to be non hazardous.
Warning:
12.
Substitution of Components May Impair Safety.
