cable
The sum of capacitance and inductance of cable and
intrinsic safe equipment must be less or equal to Ca and La
Installation notes:
1) The maximum nonhazardous location voltage is 250 VAC/DC.
2) The installation shall be in accordance with the National Electrical Code NFPA 70, Articles 504 and 505.
3) The terminals of the two individual channels shall not be interconnected in any way.
4) Install in Pollution degree 2 or better
5) Use 60 / 75 °C copper conductors with wire size AWG: (26 – 14).
6) Warning: Substitution of components may impair intrinsic safety.
