Installation

4.4 Communication

Communications cables and sensors should be connected only by people with the appropriate electrical

training.

Route communications and signal cables (Profibus, MPI, PPsolar, weather station, COM, LAN,

telephone) separately (and far away) from power cables. Power cables should cross only at right angles.

To the extent possible, you should run these cables along the top of the cabinet.

For bus connections, the order in which you connect the individual units is not important. Route the

cables so that the cable length is as short as possible and power cables are kept as far away as possible.
