Recommended diametres and lenghts for the
cables.
- Screened cables are recommended for the bus
data network.
Recommended types: J-Y(St)Y 2 x 2 x 0.6
Max. lenght: 50 meters.
- The earth connection of the cable screening
must be done once only . It is not allowed to
ground the same cable in more than one point
(see picture 3-4).
- Electric supply cables Ø = 1,5 mm
2
.
- Low voltage cables (for example sensors) Ø =
0,5 mm

max lenght 100 meters.
Picture 3: earth connection of the cable screening only
in one point.
A double earth connection cannot be effected in
case of star network of bus data.
Picture 4: Star network of bus data.
The earth connection must be effected on one
side of the star!
Do not earth connect!
