Notes:

1. Nonincendive Circuit Parameters:

Panel C Industrial Computer

Vmax = 5VDC	Voc = 5 VDC
Imax = 500mA	Isc = 500mA
Ci = 34.2µF	Ca = 1000µF
Li = 0mH	La = 5mH

2.Selected Associated Nonincendive Field Wiring Apparatus must satisfy the following requirements:

Associated Nonincendive		Panel C
Field Wiring Apparatus		Industrial Computer
Voc	≤	Vmax
Isc	≤	Imax
C a	≥	Ci + C cable
La	≥	Ci + C cable
Vmax	≥	Voc
Imax	≥	Isc
Ci + Ccable	≤	Ca
Li + Lcable	≤	La

3.If the electrical parameters of the cable are unknown, the following values may be used:

Capacitance – 60 pF/ft

Inductive – 0.20 µH/ft

4.Nonincendive Field Wiring must be installed in accordance with Article 501.4(B)(3) of the National Electrical Code ANSI/NFPA 70.
