Residual hazards

Residual hazards
Even if notes given are taken into consideration and protective measures are implemented,
the occurrence of residual risks cannot be fully prevented.
The user must take the residual hazards mentioned into consideration 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!
After mains disconnection, the power terminals will still carry the hazardous electrical voltage for the time given next to the
symbol!
High leakage current:
Carry out fixed installation and PE connection in compliance with:
EN 61800‑5‑1 / EN 60204‑1
Hot surface:
Use personal protective equipment or wait until the device has cooled down!
Protection of persons
The power terminals may carry voltage in the switched-off 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. capacitive, caused by inverter supply).
•
Careful earthing in the marked positions of the components must be carried out.
-
There is a risk of burns from hot surfaces.
•
Provide protection against accidental contact.
-
Use personal protective equipment or wait until the device has cooled down.
-
Prevent contact with flammable substances.
-
There is a risk of injury due to rotating parts.
•
Before working on the drive system, ensure that the motor is at a standstill.
-
There is a risk of accidental start-up or electric shock.
•
Motor protection
Installed thermal detectors are no full protection for the machine.
•
If necessary, limit the maximum current. Parameterize the inverter so that it will be
-
switched off after some seconds of operation with I > I
of blocking.
Integrated overload protection does not prevent overloading under all conditions.
-
The fuses are no motor protection.
•
Use a current-dependent motor protection switch.
-
Use the built-in temperature sensors.
-
Too high torques cause a fraction of the motor shaft.
•
Do not exceed the maximum torques according to the technical data on the
-
nameplate.
