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 resistance 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 sys-
tem (untreated, unpainted, uncoated mount-
ing surface).

between field distributor and mounting plate
[2] PE conductor in the supply cable
[3] Connection second PE conductor
If you install a highly flexible PE conductor
with a large cross section (e.g. 6 mm
2
), this
PE conductor also fulfills the function of an
HF-capable equipotential bonding in terms of
EMC.
•
Do not use the cable shields of data lines for equipotential bonding.
6.1.2
Data lines and 24 V supply
•
Route data lines and 24 V supply separately from cables that emit interference
(such as control cables of solenoid valves, motor cables).
6.1.3
Field distributor
•
We recommend using prefabricated SEW‑EURODRIVE hybrid cables for connect-
ing field distributors and motors.
