Safety instructions

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!
Protection of persons
The product does not provide safety-related functions.
•
A higher-level safety system must be implemented.
-
Additional monitoring and protective equipment complying with the safety regulations
-
applicable in each case must be used.
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 deenergised.
-
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.
-
Risk of burns may be caused by hot surfaces!
•
Provide for a protection against accidental contact.
-
Use the personal protective equipment or wait until the components have cooled
-
down completely!
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 danger of unintentional starting or electrical shocks!
•
Installed brakes are no fail-safe brakes.
•
The torque may be reduced by disruptive factors that cannot be influenced such as
-
ingressing oil.
Motor protection
Design with plug:
•
Never disconnect the plug when energised! Otherwise, the plug can be destroyed.
-
Switch off power supply and disable inverter prior to disconnecting the plug.
-
Installed thermal detectors are no full protection for the machine.
•
If required, limit the maximum current. Parameterise the inverter so that it will be
-
switched off after seconds of operation with I > I
of blocking.
The installed overload protection does not prevent an overload under any conditions.
-
The fuses are no motor protection.
•
Use a current-dependent motor protection switch.
-
Use the built-in thermal detectors.
-
Too high torques cause a fraction of the motor shaft.
•
The maximum torques according to catalogue must not be exceeded.
-
Lateral forces from the motor shaft may occur.
•
Align the shafts of motor and driven machine exactly to each other.
