Ci = 11 nF (+ 0.3 nF/m with cable), Li = 10 µH (+ 2 µH/m with cable)
Notes:
1. The non-incendive field wiring concept allows the interconnection of two devices with non-incendive
parameters not specifically examined in combination as a system when:
Uo or Voc ≤ Vmax, Ca or Co ≥ Ci + Ccable, La or Lo ≥ Li + Lcable, Po ≤ Pi.
2. For this current controlled circuit, the parameter I
