gle-channel wiring and active safety unit
When the wiring between the active safety unit and connector X49 of the "L
option" is to be a single-channel wiring (as illustrated above), the wiring must
be carried out as a "safe wiring". For this purpose, the following fault
exclusions must be made:
● Short circuits with other potentials
● Short circuit with 24 V
● Short circuit with ground
See also EN 61800-5-2: 2007, table D.1
When the wiring between the active safety unit and connector X49 of the "L
