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!
Protection of persons
•
The product does not provide any safety-related functions.
-
A higher-level safety system must be implemented.
-
Provide additional monitoring and protective equipment complying with the safety
regulations applicable in each case.
•
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 must be carried out at the marked positions of the components.
•
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.
•
Risk of injury from rotating parts.
-
Before working on the drive system, ensure that the motor is at a standstill.
•
There is a danger of unintentional start-up or electric shocks!
•
Installed brakes are no fail-safe brakes.
-
torque may be reduced by disruptive factors that cannot be influenced such as
ingressing oil.
Motor protection
•
Version with plug:
-
Never disconnect the plug when energized. The plug could be destroyed.
-
Switch off the voltage supply or disable the inverter prior to disconnecting the plug.
•
Installed thermal detectors are no full protection for the machine.
-
Limit the maximum current if necessary. Parameterize the inverter so that it will be
switched off after several seconds of operation with I > I
rated
especially if there is a
danger of blocking.
-
The 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 thermal detectors.
•
Excessively high torques cause a fracture of the motor shaft.
-
Do not exceed the maximum torques according to the technical data on the
nameplate.
