It should be noted that the safety functions represent only a very small
minority of the device functions.
Through selection of appropriate circuitry, it is possible to build a two-
channel structure with appropriate fault detection mechanisms for
safety functions.
The line contactor and the line fuses in the feeder cable must be
designed and dimensioned in accordance with the specifications given
in catalogs DA 65.10 and DA 65.11 or the Engineering Information. The
main switch –Q0 serves as a line disconnection device in accordance
with EN 60204-1:2006 /R9/ and is disregarded in the context of
functional safety.
