Selecting cables

Take the following criteria into account when selecting the connecting cables:
● Rated current
● Rated voltage
● Possibly a service factor
● System-dependent conditions, such as ambient temperature, routing type, cable cross-
● Requirements according to IEC/EN 60204‑1
● Dimensioning for bundled cable routing, e.g. according to DIN VDE 0298 Part 4 or

Terminal designations using the 1U1-1 as an example
U 1 - 1 Designation
Index for pole assignment for pole-changing machines where applicable. A lower
index signifies a lower speed. Special case for split winding.
x Phase designation U, V, W
x Index for winding start (1) or end (2) or if there is more than one connection per
winding
x Additional indices for cases in which it is obligatory to connect parallel power feed
cables to several terminals with otherwise identical designations
section as defined by required length of cable, etc.
