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 IEC 61800−5−1 / EN IEC 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

• Parameterize the product so that it will be switched off after some seconds of operation with I > I
especially if there is a risk 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 temperature sensors.
• Too high torques cause a fraction of the motor shaft.
- The maximum torques according to catalog must not be exceeded.
• Lateral forces on the motor shaft are possible.
- Align the shafts of motor and driven machine exactly to each other.
