the terminal box. The jumpers for the open connection must not be removed when testing the
winding; refer to the relevant circuit diagram.
● Check that the connections (star or delta) comply with the specifications on the rating
plate.
● Ensure that the connection values correspond to the information on the rating plate.
6.3.2
Terminal designation
According to IEC / EN 60034‑8, the following basic definitions apply to the terminal
designations for 3-phase machines:
Table 6-1
Terminal designations using the 1U1-1 as an example
1 U 1 - 1 Designation
x
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
6.3.3
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-
section as defined by required length of cable, etc.
● Requirements according to IEC/EN 60204‑1
● Requirements according to IEC/EN 60079-14
● Configuration notes
