Description

Note
Additional information
Refer to the layout diagrams (AO) and circuit diagrams (SP) provided on the customer DVD
supplied with the device 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 applications where energy does not have to be fed back into the line.
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 suitable for connection to supply systems grounded at the neutral
point (TN, TT) and non-grounded (IT) supply systems. The following voltages and power
ratings are available:
Line voltage
380 to 480 V AC, 3-phase
500 to 690 V AC, 3-phase
The power rating can be increased by connecting Basic Line Modules in parallel.
