Electrical installation
5.1
Installation notes
Observe the following points for electrical installation:
•
Observe the general safety notes.
•
Comply with all instructions referring to the technical data and the permissible con-
ditions where the device is operated.
5.2
Installation planning taking EMC aspects into account
5.2.1
Notes on arranging and routing installation components
Successful installation of decentralized drives depends on selecting the correct
cables, providing correct grounding and a functioning equipotential bonding.
Always apply the
relevant standards
.
Note the following:
5.2.2
Equipotential bonding
INFORMATION
Due to the extra-low voltage of DC 48 V, it is not necessary to connect a protective
earth PE.
It is, however, essential that
low-impedance, HF-capable equipotential bonding
is
provided (see also EN 60204-1 or DIN VDE 0100-540):
•
Between the ELVCD drive and the mounting rail, provide for a connection over a
wide area.
•
To do so, use a ground strap (HF litz wire), for example, to connect the ELVCD
drive and the grounding point of the plant.

5.2.3
EMC-compliant installation
INFORMATION
This drive system is not designed for operation on a public low voltage supply system
that supplies residential areas.
This is a product with restricted availability (categories C1 to C4 according to
IEC 61800-3). This product may cause EMC interference. In this case, it is recom-
mended for the operator to take suitable measures.
With respect to the EMC regulation, frequency inverters and ELVCD drives cannot be
seen as stand-alone units. Regarding EMC, they can only be evaluated when they are
integrated in a drive system. Conformity is declared for a described, CE-typical drive
system. These operating instructions contain further information.
