Description

Note
Refer to the layout diagrams and circuit diagrams provided on the customer DVD supplied
with the device 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.
Line Connection Modules are available for the following voltages and currents:
Input voltage
3 AC 380 ... 480 V
3 AC 500 ... 690 V
Table 5- 1
Terminals
U1/L1, V1/L2, W1/L3
3 AC power input
Depending on the input current, the following designs are used:
● ≤ 800 A: Main breaker with fuse switch disconnector
● > 800 A: Circuit breaker, type 3WL, with option L25 as draw-out circuit breaker
Configuration
Note
The configuration examples of the individual Line Connection Modules are used to illustrate
the positioning of the factory-fitted components. They show the maximum possible
configuration of the modules, which contain all options that can be ordered.
Refer to the layout diagrams (AO) on the customer DVD for the precise order-specific
location of the components.
