Motor connection
Overview
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.
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.
● The manufacturer of the plant/machine is responsible for the ensuring that the installation
is performed correctly.
● Observe the data on the rating plate and the circuit diagrams.
● Adapt the connecting cables to the type of use and the voltages and currents that occur.
● Use prefabricated cables from SIEMENS (not in the scope of delivery). These cables
reduce installation costs and increase operational reliability (see the Product Information).
● Make sure that the inside of the connector is clean and free of cable cuttings and
moisture.
● 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.
