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:
ƒ Safety engineering systems may only be installed and commissioned by
qualified and skilled personnel.
ƒ All control components (switches, relays, PLC, ...) and the control cabinet
must comply with the requirements of EN 954−1 and ISO 13849−2. This
includes i.a.:
–
Switches, relays in IP54 enclosure.
– Control cabinet in IP54 enclosure.
– Please refer to EN 954−1 and ISO 13849−2 for all further requirements.
ƒ It is essential to use insulated wire end ferrules for wiring.
ƒ If safety−relevant cables are installed outside the control cabinet, they have
to be protected, e.g. by means of a cable duct:
–
Ensure that there are no short circuits.
– For further measures see ISO 13849−2.
ƒ If an external force acts upon the drive axes, additional brakes are required.
Please observe that hanging loads are subject to the force of gravity!

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.
