Description

Note
Refer to the layout diagrams and circuit diagrams provided on the enclosed customer CD for
the arrangement of components and interfaces, and for wiring.
Basic Line Modules are compact supply infeeds for 2-quadrant operation (i.e. no
regenerative feedback).
Under full load, the DC-link voltage is higher than the rms value of the rated line voltage by a
factor of 1.32, and under partial load by a factor of 1.35.
They are used in cases when energy must not be fed back into the network.
If regenerative conditions occur in the drive line-up, Braking Modules must be used because
they convert the excess energy in braking resistors into heat.
Basic Line Modules are available for the following voltages and power ratings:
Line voltage
380 ... 480 V 3 AC
500 ... 690 V 3 AC
The power rating can be increased by connecting Basic Line Modules in parallel.
