The tables below state the features of the inverter cables and the protecting devices required to protect the
system against short-circuits. For the largest inverter sizes, special links with multiple conductors are provided for
each phase. For example, 2x150 in the column relating to the cable cross-section means that two 150sqmm
parallel conductors are required for each phase.
Multiple conductors shall have the same length and must run parallel to each others, thus ensuring even current
delivery at any frequency value. Paths having the same length but a different shape deliver uneven current at
high frequency.
Also, do not exceed the tightening torque for the terminals to the bar connections. For connections to bars, the
tightening torque relates to the bolt tightening the cable lug to the copper bar. The cross-section values given in
the tables below apply to copper cables.
The links between the motor and the Sinus K must have the same lengths and must follow the same paths. Use
3-phase cables where possible.
