Lenze g500-B - 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!
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 IEC 61800−5−1 / EN IEC 60204−1
Hot surface:
Use personal protecve equipment or wait unl the device has cooled down!
Protecon of persons
•
The power terminals may carry voltage in the switched-o state or when the motor is
stopped.
-
Before working, check whether all power terminals are deenergized.
•
Voltages may occur on the drive components (e.g. capacive, caused by inverter supply).
-
Careful earthing in the marked posions of the components must be carried out.
•
There is a risk of burns from hot surfaces.
-
Provide protecon against accidental contact.
-
Use personal protecve equipment or wait unl the device has cooled down.
-
Prevent contact with ammable substances.
•
There is a risk of injury due to rotang parts.
-
Before working on the drive system, ensure that the motor is at a standsll.
•
There is a risk of accidental start-up or electric shock.
Motor protecon
•
Installed thermal detectors are no full protecon for the machine.
-
If necessary, limit the maximum current. Parameterize the inverter so that it will be
switched o aer some seconds of operaon with I > I
rated
, especially if there is a risk
of blocking.
-
Integrated overload protecon does not prevent overloading under all condions.
•
The fuses are no motor protecon.
-
Use a current-dependent motor protecon switch.
-
Use the built-in temperature sensors.
•
Too high torques cause a fracon of the motor sha.
-
Do not exceed the maximum torques according to the technical data on the
nameplate.
