1.6 Factory Mutual Research Corporation (FM)and Canadian Standards association (CSA)
Factory Mutual and Canadian Standards Association I.S. Installation Drawing
Notes:
1. Control equipment connected to the Associated Apparatus must not use or generate more than 250 Vrms or Vdc.
2. The IS Barriers or Equipment (Associated Apparatus) must be FM Approved and CSACertified and the
configuration of Associated Apparatus must be FM Approved and CSACertified under the Entity Concept. The
Associated Apparatus may be installed within the Hazardous (Classified) location for which it is certified. The
Associated Apparatus and hazardous location loop apparatus manufacturer’s control drawings must be followed
when installing this equipment. An AEx [ib] Associated Apparatus is suitable only for connection to Class I, Zone
1, Hazardous (Classified) Locations and is not suitable for Class I, Zone 0, or Class I, Division 1 Hazardous
(Classified) Locations.
3. Installation should be in accordance with ANSI/ISA RP12.6 “Installation of Instrinsically Safe Systems for
Hazardous (Classified) Locations” and Article 500 of the National Electrical Code (ANSI/NFPA 70).
4. The standard conduit is suitable for Type 4X installations. All others must be mounted in a suitable enclosure.
5. The standard conduit is suitable for Class I, II and III, Division 2, Groups A, B, C, D, F & G hazardous (classified)
locations. Dust-tight conduit seal must be used when installed in Class II and Class III environments.
The connection option “D” is suitable for Class I, Division 2, Groups A, B, C and D hazardous (classified) locations.
Transducers to be installed in accordance with National Electrical Code (ANSI/NFPA 70) Division 2 hazardous
(classified) location wiring techniques.
6. The Instrinsic Safety Entity concept allows the interconnection of two FM Approved or CSA Certified intrinsically
safe devices with entity parameters not specifically examined in combination as a system when:
Ui or Vmax >Uo or Voc or Vt > 7.2 volts
li or Imax > lo or lsc or It
Ca or Co > Ci + Ccable
La or Lo > Li + Lcable
Pi > Po.
7. No revision to this drawing is permitted without prior Factory Mutual Research Approval.
