Special safety instructions for AX5000

The safety instructions are designed to avert danger and must be followed during installation, commissioning, production, troubleshooting, maintenance and trial or test assemblies.

The servo drives of the AX5000 series are not designed for stand-alone operation and must always be installed in a machine or system. After installation the additional documentation and safety instructions provided by the machine manufacturer must be read and followed.

WARNING

Serious risk of injury through high electrical voltage!

    • Never open the servo drive when it is live. Wait until the DC link capacitors are discharged. The voltage measured between the DC+ and DC- terminals (X02) must have fallen below 50 V. Opening the device (with the exception of expansion card slots) invalidates all warranty and liability claims against Beckhoff Automation GmbH.
    • Negligent, improper handling of the servo drive and bypassing of the safety devices can lead to personal injury or death through electric shock.
    • Ensure that the protective conductor is connected properly.
    • Disconnect the servo drive from the mains supply and secure it against reconnection before connecting or disconnecting the pluggable terminals.
    • Disconnect the servo drive from the mains supply and secure it against reconnection before working on electrical parts with a voltage > 50 V.
    • The DC link voltage can exceed 890 V. Wait until the DC link capacitors are discharged before touching live terminals. The voltage measured between the DC+ and DC- terminals (X02) must have fallen below 50 V.

     

    WARNING

    Danger of injury due to uncontrolled movements!

    Read and take note of chapter 'Important information for commissioning' each time before commissioning the AX5000.

     

    WARNING

    Serious risk of injury through hot surfaces!

      • The surface temperature may exceed 50 °C, resulting in a risk of burns.
      • Avoid touching the case during or shortly after operation.
      • Leave the servo drive to cool down for at least 15 minutes after it is switched off.
      • Use a thermometer to check whether the surface has cooled down sufficiently.

       

      CAUTION

      Hazard to persons!

        • Carefully read this manual before using the servo drive thoroughly, paying particular attention to the safety instructions. In the event of any uncertainties please notify your sales office immediately and refrain from working on the servo drive.
        • Only well trained, qualified electricians with sound knowledge of drive equipment may work on the device.
        • During the electrical installation it is essential to ensure that the correct fuses/protective circuit breakers are used between the mains supply and the servo drive. Further information can be found in the "Electrical installation" section.
        • If a servo drive is installed in a machine it must not be commissioned until proof of compliance of the machine with the latest version of the EC Machinery Directive has been provided. This includes all relevant harmonised standards and regulations required for implementation of this Directive in national legislation.

         

        Notice

        Hazard to equipment and environment!

          • During installation it is essential to ensure that the specified ventilation clearances and climatic conditions are adhered to. Further information can be found in the "Technical data" and "Mechanical installation" sections.
          • If the servo drive is operated in contaminated ambient air, the cooling openings must be checked regularly for blockage. These checks should be carried out several times per day.
          • The servo drives contain components at risk from electrostatic discharge caused by improper handling:
            - Please ensure you are electrostatically discharged before touching the servo drive directly.
            - Avoid contact with highly insulating materials (synthetic fibres, plastic film etc.).
            - Place the servo drive on a conductive surface.
            - Do not touch the motor plug during operation of the AX5000.
