Lenze i550 - Residual Hazards

Residual hazards
Even if notes given are taken into consideraon and protecve measures are implemented, the occurrence
of residual risks cannot be fully prevented.
The user must take the residual hazards menoned into consideraon in the risk assessment for his/her
machine/system.
If the above is disregarded, this can lead to severe injuries to persons and damage to property!
Product
Observe the warning labels on the product!
DANGER!
Danger to life due to electrical voltage!
The product's power connecons can sll be carrying voltage when the mains supply has been switched o.
Possible consequences: Death, severe injury, or burns
▶
Do not touch the power connecons immediately.
▶
Take note of the corresponding warning plates on the product.
▶
Check power terminals for isolaon from supply.
Dangerous electrical voltage:
Before working on the product, make sure there is no voltage applied to the power terminals!
Aer mains disconnecon, the power terminals will sll carry the hazardous electrical voltage for the me
given next to the symbol!
Electrostac sensive devices:
Before working on the product, the sta must ensure to be free of electrostac charge!
High leakage current:
Carry out xed installaon and PE connecon in compliance with:
EN 61800−5−1 / EN 60204−1
Hot surface:
Use personal protecve equipment or wait unl the device has cooled down!
Degree of protecon - protecon of persons and device protecon
•
Informaon applies to the mounted and ready-for-use state.
Motor protecon
With some sengs of the inverter, the connected motor can overheat.
•
E. g. by longer operaon of self-venlated motors at low speed.
•
E. g. by longer operaon of the DC-injecon brake.
Protecon of the machine/system
Drives can reach dangerous overspeeds.
•
E. g. by seng high output frequencies in connecon with motors and machines not suitable for this
purpose.
•
The inverters do not provide protecon against such operang condions. For this purpose, use
addional components.
Switch contactors in the motor cable only if the controller is inhibited.
•
Switching while the inverter is enabled is only permissible if no monitoring funcons are acvated.
