Danger!
Danger to life through improper installation
Improper installation of the safety engineering systems can cause an
uncontrolled restart of the drives.
Possible consequences:
ƒ Death or severe injuries
Protective measures:
Total cable length between X60 and the connected components (e.g. sensors,
devices, etc.) > 3 m:
ƒ It is essential to shield the cable installed between X60 and the connected
components:
– Connect the shield at least to X60 in the connector shell.
– If possible, connect the shield to the connected component as well.
Total cable length between X60 and the connected components (e.g. sensors,
devices, etc.) < 3 m:
ƒ
Unshielded wiring is permitted.

Note!
Please observe during transport, storage and operation:
ƒ Cover unused connectors for control connections and interfaces with the
plastic covers provided to preserve the certified safety technology features.

Danger!
If the request for the safety function is cancelled, the drive will restart
automatically.
You must provide external measures which ensure that the drive only restarts
after a confirmation (EN 60204).

Note!
By means of the function “safe torque off” (STO), an “emergency-off” in
accordance with EN 60204 can be effected, as the three mains phases are
safely separated.
During operation
After the installation is completed, the operator must check the wiring of the safety
function.
The functional test must be repeated at regular intervals. The time intervals to be selected
depend on the application, the entire system and the corresponding risk analysis. The
inspection interval should not exceed one year.
