6.3.3 Laying cables
● Lay the cables in accordance with IEC/EN 60364-5-52.
● Use EMC cable glands for fixed cables. Screw the EMC cable glands into the threaded
holes in the entry plate, which can be unscrewed.
● Use shielded cables whose shields are conductively connected to a large area of the
terminal box of the motor via EMC cable glands.
● In the case of aluminum connecting bars, insert a steel washer between the cable lug and
the connecting bar. This prevents contact corrosion.
● Arrange the exposed connecting cables in the terminal box so that the PE conductor has
excess length and the insulation of the cable strands cannot be damaged.
● Close off unused bushings with a metal threaded plug. This is the way to achieve a high
frequency-proof shielding.
6.3.4 Electrical connection data
Cable entry and technical connection data depend on the mounted terminal box. You can find
more information on the terminal box that is mounted in the ordering documentation or in the
catalog.
