8.4 Cable cross-sections and connections on SINAMICS S150 cabinet units
8.4.1 Recommended and max. possible cable cross-sections for line and motor connections
The following tables show the recommended and maximum connectable cable cross-sections on the line and motor
sides. The recommended cross-sections are based on the fuses specified in catalog D 21.3. These are valid for PVC-
insulated, copper 3-wire cables installed horizontally in air with a permissible conductor temperature of 70 °C (e.g.
Protodur NYY or NYCWY) at an ambient temperature of 40 °C and for singly routed cables. When the conditions
differ from the above stated (cable routing, cable grouping, ambient temperature), the relevant correction factors as
stated in IEC 60364-5-52 must be applied.
When aluminum cables are used, the recommended cross-sections given in the table must be increased by a factor
of 1.3. This can be done either by enlarging the conductor cross-section or by increasing the number of parallel
cables. It is important to note, however, that the cable cross-sections must not exceed the specified maximum
permissible dimensions at the converter and must be suitable for connection to the motor terminal box.
