Notes
1. Installation:
A. Installations in the us should be in accordance with ANSI/ISA RP12.06.01“installation of intrinsically safe systems for hazardous (classified) locations” and
the latest edition of the national electrical code (ANSI/NFPA 70)
B. Installation in Canada should be in accordance with the latest edition of the C22.1 Canadian Electrical code, part I.
C. Installations in Europe shall be in accordance with latest editions of the wiring practices for the country of origin and En 60079-14.
D. Installations for IECEx certification shall be in accordance with latest editions of the wiring practices for the country of origin.
2. The subject equipment is FM approved and FM approved for Canada for the following hazardous (classified) locations and protection methods:
Class 1, division 1, group ABCD, T4
Tamb: -20 c to +60 c
3. Zener barrier or galvanically isolated FM approved (US) or Canadian certified (for Canada) associated apparatus installed in accordance with the
manufacturer’s
instructions.
4. The control room equipment connected to associated apparatus must not generate more than 250 Vrms or VDC or the marked um on the associated apparatus
whichever is less.
5. Maintain the following relationship between intrinsic safety (entity) parameters of oxy.iq and associated apparatus:
Oxy.IQ Ui (Vmax) ≥ associated apparatus Uo (Voc)
Oxy.IQ li (lmax) ≥ associated apparatus lo (lssc)
Oxy.IQ Pi (Pmax) ≥ associated apparatus Po
Oxy.IQ Ci + Ccable ≤ associated apparatus Co (Ca)
Oxy.IQ Li + Lcable ≤ associated apparatus Lo (La)
6. Resistance between intrinsically safe ground and earth ground shall be less than 1 ohm.
7. Warning - to prevent ignition of flammable or combustible atmospheres, disconnect power before servicing.
Avertissement - pour éviter l’inflammation d’atmosphères inflammables ou combustibles, débrancher l’alimentation avant l’entretien.
8. Warning - substitution of components may impair intrinsic safety.
Avertissement - remplacement des composants peut compromettre la sécurité intrinsèque.
9. The associated apparatus must be ATEX certified for installations in europe.
10. The associated apparatus must be IECEx certified for IECEx installations .
11. When installed in a division 2 location the model oxy.IQ oxygen transmitter shall be installed in a final enclosure accepting a division 2 wiring method per the NEC / CEC.
