4.3.1
Preventive measures
Observe the following rules:
•
Observe the permitted EMC limit value ranges for the devices.
For detailed information about EMC-compliant installation, refer to the publication
"Electromagnetic Compatibility in Drive Engineering" from SEW-EURODRIVE.
•
Connect only ohmic/inductive loads, such as motors, to motor connection. Never
connect capacitive loads.
•
Implement the prescribed preventive measures for preventing electrical hazards
(ground connection or protective separation/equipotential bonding and ESD pro-
tection).
•
Use the shortest possible low-impedance, HF-compatible cables, with the stipu-
lated minimum cross sections and colors.
4.3.2
Using prefabricated cables
SEW‑EURODRIVE uses prefabricated cables for certifications, type tests and ap-
proval of the devices. The cables available from SEW‑EURODRIVE meet all the re-
quirements necessary for the functions of the device and the connected components.
All observations of the device are made on the basis of the basic device in conjunction
with all components to be connected to the device and all corresponding connection
cables.
For this reason, SEW‑EURODRIVE recommends that you only use the prefabricated
cables listed in the documentation. When using devices with integrated safety func-
tions according to EN ISO 13849, you also have to adhere to all the conditions and re-
quirements for the installation and routing of cables described in the documentation for
the devices concerning functional safety.
4.3.3
Using third-party cables
If third-party cables are used – even if these cables are technically adequate –
SEW‑EURODRIVE does not accept any liability and cannot guarantee device proper-
ties or functions.
If you use third-party cables for connecting the device and connected components, en-
sure their compliance with applicable national regulations. Note that the technical fea-
tures of the device or unit network might be affected inadvertently when using third-
party cables.
This concerns in particular the following properties:
•
Mechanical properties (e.g. IP degree of protection, cable carrier suitability)
•
Chemical properties (e.g. silicone and halogen free, resistance to substances)
•
Thermal properties (e.g. thermal stability, increase in device temperature, flam-
mability class)
•
EMC behavior (such as interference emission limit values, compliance with inter-
ference immunity values stipulated in standards)
•
Functional safety (approvals according to EN ISO 13849-1)
Third-party cables not explicitly recommended by SEW‑EURODRIVE must meet at
least the requirements of the following standards and have been permitted according
to these standards:
•
IEC 60309
•
IEC 61984
•
IEC 60204
