6.7 Connecting converters
6.7.1 Connecting converters
NOTICE
Excessively high supply voltage
Material damage can occur if the supply voltage is too high for the insulation system.
The machines can be operated wit
h line voltages ≤ 500 V with SINAMICS G converters
and SINAMICS S converters (uncontrolled and controlled infeed) when maintaining the
permissible peak voltages.
The maximum permissible voltage rate of rise (gradient) is 9 kV/µs.
Û
conductor-conductor
≤ 15 00 V; Û
conductor-ground
≤ 1100 V
For VSD machines, the following data apply:
Û
conductor-conductor
≤ 1600 V, Û
conductor-ground
≤ 1400 V, voltage rise times of ts > 0.1 µs.

System, converter-cable-electrical machine
Please observe the information in accordance with EN / IEC 60034-17 and EN / IEC 60034-
25 regarding winding stress. For line supplies with operating voltages up to 690 V, the
maximum value of the voltage peaks at the end of the cable must not exceed twice the value
of the converter's DC-link voltage.
6.8 Final measures
Before closing the terminal box/terminal base of the machine enclosure, check the following:
● Establish the electrical connections in the terminal box in accordance with the details in
the sections above and tighten with the correct torque.
● Maintain air clearances between non-insulated parts:
≥ 5.5 mm up to 690 V, ≥ 8 mm up to 1000 V.
● Avoid protruding wire ends!
● In order not to damage the cable insulation, freely arrange the connecting cables.
● Connect the machine corresponding to the specified direction of rotation.
● Keep the inside of the terminal box clean and free from trimmed-off ends of wire.
● Ensure that all seals and sealing surfaces are undamaged and clean.
● Correctly and professionally close unused openings in the terminal boxes.
