The cable used to interconnect the devices needs to comply with the following
parameters:
Loop resistance R’: 15 … 150
Ω
/km; Inductance per unit length L’: 0,4 … 1 mH/km
Capacitance per unit length C’: 80 … 200 nF/km
(C’ = C’ line/line + 0,5 C’ line/screen if both line are floating)
(C’ = C’ line/line + C’ line/screen if the screen is connected to one line)
Length of spur cable: max. 30 m
Length of trunk cable: max. 1 km
Length of splice : max. 1 m
WARNING
- Substitution of components may impair Intrinsic Safety
