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.
Power is fed to the drive line-up via Line Modules, which generate a DC voltage from the line
voltage and, therefore, supply energy to the Motor Modules connected to the DC link. They
are suitable for connection to grounded (TN, TT) and non-grounded (IT) systems. The Line
Modules are connected to the incoming supply via Line Connection Modules and are
equipped with a radio interference suppression filter in accordance with EN 61800-3,
Category C3 as a standard feature.
Line Connection Modules contain the line-side infeed with main breaker and fuse switch
disconnector or circuit breaker and provide the connection between the plant power system
and the Line Modules.
