Lenze i550 Series - Functional Safety

Funconal safety
DANGER!
Improper installaon of the safety engineering system can cause an uncontrolled starng
acon of the drives.
Possible consequences: Death or severe injuries
▶
Safety engineering systems may only be installed and commissioned by qualied and skilled
personnel.
▶
All control components (switches, relays, PLC, ...) must comply with the requirements of the
EN ISO 13849−1 and the EN ISO 13849−2.
▶
Switches, relays with at least IP54 enclosure.
▶
Control cabinet with at least IP54 enclosure.
▶
It is essenal to use shields for the wiring.
▶
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!
▶
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
▶
The maximum voltage (maximum rated) at the safety inputs is 30 V DC. The user must make
provisions to avoid that this voltage is exceeded.
