The terminal diagram pasted into the terminal box shows only the conditions required for
connection to the line power supply, without detailed representation of inner connections or
winding components.
6.4 Connecting cables
The power cables are connected in the terminal box. Supplementary connections for auxiliary
circuits with terminal strips for cable cross-sections of up to 2.5 mm
post insulators or Terminal Boards (depending on construction type) are provided for
connecting the excitation circuit.
● Terminal boxes can also be rotated by 90° in each case depending on the connecting
● Connect the cables in such a way as to ensure a permanent and reliable electrical
● Make sure the protective conductor connection is secure.
