Basic Line Modules with cold plate

4.8.1

Description

The Basic Line Modules generate a non-regulated DC voltage, which matches the rectified
line input voltage, from the 3-phase line voltage and feed this DC voltage into the DC link.
One Basic Line Module can supply one or more Motor Modules with power via the DC link.
To reduce the energy, e.g. for emergency retraction, the 20 kW and 40 kW Basic Line
Modules feature a control for an external braking resistor.
For 100 kW Basic Line Modules, an external braking unit is required for degradation of
energy. Either Braking Modules Booksize Compact (also in a parallel connection) or a
MASTERDRIVES braking unit (see Chapter "Braking units for 100 kW Basic Line Modules
(Page 517)") can be used.
A line contactor can be installed on the line side if the system has to be electrically isolated
from the line supply.
Basic Line Modules are suitable for direct operation on TN, IT and TT systems. The Line
Modules have an integrated overvoltage protection function.
The 100 kW Basic Line Module features basic interference suppression, the 20 kW and
40 kW Basic Line Modules do not.
The ratio between the line short-circuit power (system fault level) and the rated power must
be ≥ 30.
Data regarding the radio interference voltage categories and maximum total cable lengths
that can be achieved, see Chapter Combination options, Line Modules with line reactors and
line filters (Page 135).
