Installation planning taking EMC aspects into account
INFORMATION
This drive system is not designed for operation on a public low voltage supply system
that supplies residential areas.
MOVIMOT
®
can cause EMC interference within the permitted limit range according to
EN 61800-3. In this case, it is recommended for the operator to take suitable meas-
ures.
For detailed information on EMC-compliant installation, refer to the SEW publication
Drive Engineering – Practical Implementation, "Electromagnetic Compatibility in Drive
Engineering".
Successful installation of decentralized drives depends on selecting the correct
cables, providing correct grounding and a functioning equipotential bonding.
Always adhere to the
relevant standards
.
Observe the notes in the following chapters in particular.
6.1.1
Equipotential bonding
Low-impedance and HF-capable equipotential bonding must be provided independent
of the PE connection (see also VDE 0113 or VDE 0100 part 540).
Establish a connection over a wide surface area between the field distributor and the
system (untreated, unpainted, uncoated mounting surface).
Do not use the cable shields of data lines for equipotential bonding.

If you install a highly flexible PE conductor with a large cross section (e.g.
6 mm

), this PE conductor also fulfills the function of an HF-capable equipotential
bonding in terms of EMC.
