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.
