INSTALLATION
To prevent potential differences between individual system components, all devices on the
bus must have the same potential. To achieve this, all devices must be connected to each
other with a potential equalization conductor (see “Potential equalization line”, page 33).
Fig. 26: Potential equalization line
CAUTION: Never use the line shield as potential equalization
The line shield only serves to shield against high-frequency interference and may not be
used as potential equalization.
