Funconal safety
DANGER!
Improper installa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.
▶
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.
DANGER!
Automac restart if the request of the safety funcon is deacvated.
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.
NOTICE
Excessively high humidity or condensaon
Malfuncon or destrucon of the safety component
▶
Only commission the safety component when it has acclimased.
NOTICE
Overvoltage
Destrucon of the safety component
▶
Make sure that the maximum voltage (maximum rated) at the safe inputs does not exceed 32 V DC.
