3.2 Electrical connection for signal converter
Bus cable - Shielding and grounding
The statements of the FISCO model only apply if the used bus cable meets the required
specifications.
In order to ensure optimum electromagnetic compatibility of systems it is important that the
system components, and in particular the bus cables, are shielded. These shields must have as
few gaps as possible.
Use the shortest possible length of shield wire to connect the electrical cable to the functional
earth (FE) terminal.
INFORMATION!
The PROFIBUS PA interface of the signal converter will operate only if the power supply is
connected/available. The device terminal is not sensitive to electrical polarity.
