Electrical installation

WARNING

Do not work on live electrical components

Only work on the distributed servo drive system when the voltage has dropped to < 50 V. Ensure that the protective conductor is connected properly. Never loosen electrical connections when live. Disconnect all components from the mains and secure them against being switched on again.

There is still a life-threatening voltage of > 875 VDC on the capacitors after disconnection from the supply network. Serious or even fatal injuries may result if this is ignored.

WARNING

Observe the discharge times of the capacitors

Observe the following delay times after disconnecting from the mains supply:

    • 30 minutes at AMP8yxx
    • 30 minutes for AX883x
    • There is still a life-threatening voltage of > 875 VDC on the capacitors after disconnection from the supply network. Serious or even fatal injuries may result if this is ignored.

    WARNING

    Danger due to insufficient earthing

    Inadequate earthing can lead to electric shocks, malfunctioning, or even fires and therefore represents a significant safety risk.

    • The protective conductor must be properly connected and fixed to earth
    • Only use standardized and tested ground cables and ground connections
    • Carry out regular inspections of the earthing connection to ensure that there is no corrosion, damage, or loosening

    Notice

    Electromagnetic compatibility

    Establish conductive connection of all components. For larger applications, implement the potential equalization via PE rails.

    Improper grounding or faulty contacting can lead to damage to the distributed servo drive system or to EMC interference emissions. The minimum cross-sections of separate protective conductors can be found in EN 61439-1.
