4.15 Protective connection and function equipotential bonding
4.15.1 Rules to dimension the protective connection
Description
WARNING
Electric shock caused by high leakage currents when the protective conductor in the line
supply cable is interrupted
The drive components conduct a high leakage current via the protective conductor. Touching
conductive parts when the protective conductor is interrupted can result in death or serious
injury.
• Carefully comply with the applicable regulations when dimensioning the protective
conductor.
Observe the following requirements for the protective conductor connection of the control
cabinet:
• All system and machine parts must be incorporated in the protective concept.
• For increased leakage currents, carefully ensure that the local regulations for protective
conductors at the
installation site are complied with.
• The protective connection for the motors used must be established through the motor cable.
• Use copper cables with a cross-section (> 2.5 mm
2
) for the ground connection of PROFIBUS
participants.
