Establishing the connection
Attach the cables to the terminal block -X101 of the next module:
● 4-phase cable (1-2): for the line voltage to terminals 1 and 2
● 4-phase cable (3-4): for 230 V AC to terminals 3 and 4
● 2-phase cable (1-2): for 24 V DC to terminals 5 and 6
Note
Establishing the connection for Basic Line Modules
Basic Line Modules do not contain auxiliary power modules. The 24
V DC voltage supply is
ed by connecting the 2-phase cable included in the Basic Line Module to the auxiliary
power module of the adjacent cabinet.
Connecting to the infeed
Description
The voltages provided on the auxiliary power supply system must be produced by an
auxiliary power supply (e.g. by an Auxiliary Power Supply Module or by Option K76 "Auxiliary
voltage generating unit in the Line Connection Module").
If an Auxiliary Power Supply Module is not available to supply power to the auxiliary power
supply system or if the Auxiliary Power Supply Module and the Cabinet Modules to be
supplied are installed in different parts of the cabinet line-up, an auxiliary power module in
the Line Connection Module can be used to feed power to the auxiliary power supply
system. Further alternatives for feeding power are in the first or last auxiliary power module
of the drive line-up. The maximum current-carrying capacity of the auxiliary power supply
system is 80 A. In the case of the external power supply, this must be fuse protected on the
line side.
