Electrical installation

Serious injuries caused by residual voltage

There is still a life-threatening voltage of > 875 VDC on the capacitors after disconnection from the supply network. Failure to follow the safety instructions may result in serious or fatal injuries.

• Disconnect all components from the power source
• Secure the machine against restarting
• Never disconnect electrical connections while they are live
• Once the voltage has dropped below 50 V, work on the distributed servo drive system can resume
• Ensure that the protective conductor is properly connected

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

Damage due to improper grounding and faulty contacting

Improper grounding or faulty contact can lead to damage to the distributed servo drive system. or EMC interference emissions.

• Establish a conductive connection of all components
• The minimum cross-sections of separate protective conductors can be found in DIN EN 61439-1
• Only use shielded cables
• Ground the shields of the pre-assembled cables via the mounting plate and place the star point centrally on the unpainted mounting plate
• For larger applications, implement the potential equalization via PE rail
