Danger!
Danger to life through improper installation
Improper installation of the safety engineering systems can cause
anuncontrolled starting action of the drives.
Possible consequences:
ƒ Death or severe injuries
Protective measures:
Total cable length between X82 and its connected components (e.g. sensors,
devices, ...) > 3 m:
ƒ Up to HW version 1A, a shielded laying system must be used for the cable
between X82 and its connected components:
– The shield must at least cover the shield connection at the installation
backplane.
– The shield should also cover the connected component if possible.
ƒ From HW version 1A onwards, unshielded wiring is permissible.
Total cable length between X82 and its connected components (e.g. sensors,
devices, ...) < 3 m:
ƒ Unshielded wiring is permissible.
