MMF32 design

The following figure shows the connection of the equipotential bonding and the PE conductor:

[1]

Conductive connection over a wide surface between the decentralized frequency inverter and the mounting plate, in case the entire contact surface is electrically conductive (e.g. unpainted).

[2]

2nd PE conductor via separate terminals

[3]

PE conductor in the supply system cable

[4]

EMC-compliant equipotential bonding, e.g. via grounding strap (HF litz wire). The contact surfaces must be electrically conductive (e.g. unpainted).
