Use of prefabri-
cated cables with
plug connectors
SEW-EURODRIVE uses prefabricated cables for certifications, type tests and approval
of the units. The cables available from SEW-EURODRIVE meet all the requirements
necessary for the functions of the unit and the connected components. The units under
consideration are always the basic units including all connected components and corre-
sponding connection cables.
This is why SEW-EURODRIVE recommends to use only the prefabricated cables spec-
ified in the documentation.
When using units with integrated safety functions according to EN ISO 13849, you also
have to adhere to all the conditions and requirements for the installation and routing of
cables described in the documentation for the units concerning functional safety.
Use of third-party
cables with plug
connectors
If third-party cables are used – even if these cables are technically adequate – SEW-
EURODRIVE does not accept any liability and cannot guarantee unit properties or func-
tions.
When using third-party cables to connect the unit and/or unit components, make sure to
comply with all applicable national regulations. Note that the technical features of the
unit or system of units might be affected inadvertently when using non-SEW cables. This
concerns in particular the following properties:
• Mechanical properties (such as IP degree of protection, cable carrier suitability)
• Chemical properties (such as the absence of silicone and halogen, resistance
against substances)
• Thermal properties (e.g. temperature stability, heating of the unit, flammability class)
• EMC behavior (such as interference emission limit values, compliance with interfer-
ence 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 plug connector standards:
• IEC 60309
• IEC 61984
