Associated Apparatus
Associated apparatus output current must be limited by a resistor such that the output voltage-current
plot is a straight line drawn between open-circuit voltage and short-circuit current.
Associated apparatus may be in a Division 2 or Zone 2 location if so approved.
Selected associated apparatus must be third party listed as providing intrinsically safe circuits for the
application, and have Voc or Vt not exceeding Vmax, Isc or It not exceeding Imax, and the Po of the
associated apparatus must be less than or equal to the Pmax of the intrinsically safe equipment, as shown in
Table 1.
Capacitance and inductance of the field wiring from intrinsically safe equipment to the associated
apparatus shall be calculated and must be included in the system calculations as shown in Table 1.
capacitance, Ccable, plus intrinsically safe equipment capacitance, Ci must be less than the marked
capacitance, Ca shown on any associated apparatus used. The same applies for inductance (Lcable, Li and
La respectively). Where the cable capacitance and inductance per foot are not known the following values
shall be used: 60pF/ft., Lcable = 0.2µH/ft.
If Po of the associated apparatus is not known, it may be calculated using the formula Po=(Voc*Isc)/4
Associated apparatus must be installed in accordance with its manufacture's control drawing and Article 504
of the National Electrical Code (ANSI/NFPA 70) for installation in the United, or Section 18 of the
Canadian Electrical Code for installation in Canada.
When required by the manufacturer's control drawing, the associated apparatus must be connected to a
suitable ground electrode per the National Electrical Code (ANSI/NFPA 70), or the Canadian Electrical Code,
or other local installation codes, as applicable. The resistance of the ground path must be less than 1 ohm.
Control equipment must not use or generate more than 25V rms or dc with respect to earth.
Associated apparatus must not be used in combination unless permitted by the associated apparatus
certification.
