Selecting the cables
● When choosing connecting cables, you must take into account the rated current, possibly
the service factor, and the plant-specific conditions (e.g.ambient temperature, routing
type, etc. to IEC/EN 60204-1).
Connecting using cable lugs
Connection with cable lugs is only permitted for conductor cross-sections ≥ 70 mm2 to
300mm², to prevent the cable lugs twisting on connection.
● Select the cable lugs according to the required cable cross-section and screw size.
