5.1.3 Cable selection, routing and shielding
WARNING
Electric shock caused by faulty installation.
Severe or fatal injuries.
• Take the utmost care when installing the units.
• Observe the connection examples.
For more information on cable selection, routing and shielding, refer to chapter "Cable
routing and shielding".
5.1.4 Equipotential bonding
Regardless of the PE connection, it is essential that low-impedance, HF-capable
equipotential bonding is provided (see also EN60204-1 or DIN VDE0100-540):
• Provide for a connection over a wide area between the device and the mounting
rail.
• To do so, use a ground strap (HF litz wire), for example, to connect the device and
the grounding point of the system.
• Do not use the cable shields of data lines for equipotential bonding.
INFORMATION
For detailed information on equipotential bonding for decentralized inverters and
drive units, refer to the publication "Equipotential Bonding of Decentralized Inverters"
by SEW‑EURODRIVE.
