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.
Polarity reversal has no effect on the function. The cable shield should be connected with
minimum length to the functional ground FE.

DANGER!
The signal converter must be properly grounded to avoid personnel shock hazard. All directions,
operating data and connection diagrams do not apply to devices used in hazardous areas; in such
cases, read the special Ex instructions without fail!
