Notice
For cables 30m long or more, there is a risk that individual bus nodes will have different
ground potentials. In this case, establish a potential equalization between the bus nodes
using a separate cable.
For potential equalization, the best choice is a flexible cable with a minimum conductor
cross-section of 10mm
