1.
The Entity Concept allows interconnection of intrinsically safe apparatus with associated apparatus not specifically examined in combination
as a system. Selected Intrinsically Safe Equipment must be third party listed as intrinsically safe for the application and have intrinsically
safe entity parameters conforming with the following:

It should be noted, however, for installation in which both the Ci and Li of the intrinsically safe equipment exceed 1% of the Ca (or Co) and
La (or Lo) parameters of the associated apparatus (excluding the cable), only 50% of Ca (or Co) and La (or Lo) parameters are applicable
and shall not be exceeded.
2.
Capacitance and inductance of the field wiring from the intrinsically safe equipment to the associated apparatus shall be calculated and
must be included in the system calculations as shown under 1. Where the cable capacitance and inductance per foot are not known, the
following values shall be used: C
= 60 pF / ft., L
= 0.2 µH / ft.

3.
The output current of this associated apparatus is limited by a resistor such that the output voltage-current plot is a straight line drawn
between open-circuit voltage and short-circuit current.
4.
This associated apparatus has not been evaluated for use in combination with another associated apparatus.
5.
This associated apparatus may also be connected to simple apparatus as defined in Article 504.2 and installed and temperature classified
in accordance with Article 504.10(B) of the National Electrical Code (ANSI/NFPA70), or other local codes applicable.
6.
Associated apparatus must be installed in an enclosure (which meets the requirements of ANSI/ISA S82) suitable for the application in
accordance with the National Electrical Code (ANSI/NFPA 70) for installation in the United States, the Canadian Electrical Code for
installation in Canada, or other local codes, as applicable.
7.
When using as non-incendive device for Class I, Division 2 or Class I, Zone 2 do not snap equipment onto or off the pac-Bus 9194, or
connect and disconnect non-intrinsically safe-lines unless power has been removed or the area is known to be non hazardous.
8.
Intrinsically safe circuits must be wired separately in according with Article 504.20 of the National Electrical Code (ANSI/NFPA 70) for
installation in the United States, the Canadian Electrical Code Part 1, Appendix F for installation in Canada, or other local codes, as
applicable.
9.
When multiple circuits extend from the same piece of associated apparatus, they must be installed in separate cables or in one cable
having suitable insulation. Refer to Article 504.30(B) of the National Electrical Code (ANSI/NFPA 70) and Instrument Society of America
Recommended Practice ISA RP12.6 for installing intrinsically safe equipment.
10. Electrical apparatus connected to an intrinsically safe system shall not use or generate voltages > 253 V AC resp. > 125 V DC. (U
11. Ambient temperature: -20°C ... +60°C (any mounting position)
WARNING – EXPLOSION HAZARD
Substitution of components may impair suitability for Class I, Division 2 or Class I, Zone 2.
Do not disconnected equipment unless power has been removed or the area is known to be non-hazardous.
AVERTISSEMENT - RISQUE D'EXPLOSION
Le remplacement des composants peut remettre en cause la compatibilité avec la classe I, division 2 oú classe I, zone 2.
Ne déconnecter l'appareil que s'il est hors tension ou si l'atmosphère est exempte de concentrations inflammables.
