Connection notes
NOTICE
Destruction of the motor if it is directly connected to the three-phase line supply
The motor will be destroyed if it is directly connected to the three-phase line supply.
•
Only operate the motors with the appropriately configured converters.
NOTICE
Damage to electronic components as a result of electrostatic discharge
Electrostatically sensitive devices (ESD) can be damaged or destroyed by electrostatic
discharge.
•
Observe the ESD protection measures.
•
Only grounded personnel with grounded tools may touch the component connections.
•
Heed the EMC information provided by the manufacturer of the converter.
●
Use prefabricated cables from SIEMENS (not in the scope of delivery). These cables
reduce installation costs and increase operational reliability (see the Product Information).
●
The manufacturer of the plant/machine is responsible for ensuring that installation is
performed correctly.
●
Observe the data provided on the rating plate and the circuit diagrams.
●
Adapt the connection cables to the type of use and the voltages and currents that occur.
●
When fed from a converter, high-frequency current and voltage oscillations in the motor
feeder cables can cause electromagnetic interference. Therefore, use shielded power
cables.
●
Make sure that the inside of the connector is clean and free of cable cuttings and
moisture.
●
Avoid protruding wire ends.
●
Check that the degree of protection is complied with at the seals and sealing surfaces of
the connectors.
●
Secure connecting cables against torsion, tensile and compressive strain, and protect
them against kinking. It is not permissible to subject the connector to continuous force.
●
Insert the coding groove of the plug-in connection into the socket until flush and tighten
the screw cap by hand in as far as it will go.
