Second level distribution with PE equipotential bonding
Short connection from the PE terminal to the metal frame.
Electrical connection of motor cable shield and connector body.
Electrical connection of motor cable shield and motor terminal box via electrically conductive PG
Conventional grounding system.
• Standard, heavy-power PE conductors without special high-frequency properties.
• Ensures low frequency equipotential bonding as well as protection against injury.
