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!
DANGER!
Danger to life due to electrical voltage!
The product's power connections can still be carrying voltage when the mains supply has been switched off.
Possible consequences: Death, severe injury, or burns
▶ Do not touch the power connections immediately.
▶ Take note of the corresponding warning plates on the product.
▶ Check power terminals for isolation from supply.
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!
Electrostatic sensitive devices:
Before working on the product, the staff must ensure to be free of electrostatic charge!
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!
Degree of protection - protection of persons and device protection
• Information applies to the mounted and ready-for-use state.
Motor protection
With some settings of the inverter, the connected motor can be overheated.
• E. g. by longer operation of self-ventilated motors at low speed.
• E. g. by longer operation of DC-injection braking.
Protection of the machine/system
Drives can reach dangerous overspeeds.
• E. g. by setting high output frequencies in connection with motors and machines not suitable for this
purpose.
• The inverters do not provide protection against such operating conditions. For this purpose, use
additional components.
Switch contactors in the motor cable only if the controller is inhibited.
• Switching while the inverter is enabled is only permissible if no monitoring functions are activated.
