DANGER!
Improper ins
tallaon of the safety engineering system can cause an uncontrolled starng
acon of the drives.
Possible consequence: Death or severe injuries
▶
Safety engineering systems may only be installed and commissioned by qualied personnel.
▶
The complete wiring must be designed in accordance with EMC requirements.
▶
All control components (switch, relay, PLC, ...) must comply with the requirements of
EN ISO 13849−1 and the EN ISO 13849−2.
▶
Switches, relays with at least IP54 degree of protecon.
▶
Always mount devices with a degree of protecon lower than IP54 in control cabinets with a
minimum degree of protecon of IP54.
▶
The wiring must be shielded.
▶
It is essenal to use insulated wire end ferrules for wiring.
▶
All safety-relevant cables outside the control cabinet must be protected, e.g. by means of a
cable duct.
▶
Ensure that no short circuits can occur according to the specicaons of the
EN ISO 13849−2.
▶
All further requirements and measures can be obtained from the EN ISO 13849−1 and the
EN ISO 13849−2.
▶
If an external force acts upon the drive axes, addional brakes are required. Please observe
that hanging loads are subject to the force of gravity!
▶
For safety-related braking funcons, use safety-rated brakes only.
▶
The user has to ensure that the inverter will only be used in its intended applicaon within
the specied environmental condions. This is the only way to comply with the declared
safety-related characteriscs.

Possible consequences: Death or severe injuries
▶
You must provide external measures according to EN ISO 13849−1 which ensure that the
drive only restarts aer a conrmaon.
