Line-side power components

2.1

General

Line-side power components are used to protect the connected components against
transient or continuous overvoltages and ensure that prescribed limit values are adhered to.
2.2

Line filters for Basic Line Modules

2.2.1

Description

The line filters limit the conducted interference emitted by the Power Modules to permissible
values.
To reduce emissions, the Line Modules are equipped as standard with a line filter in
accordance with the limit values defined in category C3 (second environment). The
additional line filters described here can be fitted for use in the first environment (category
C2).
In conjunction with line reactors, line filters limit the conducted interference emitted by the
Power Modules to the limit values defined in product standard EN 61800-3. Provided that the
system has been set up in accordance with the EMC installation guidelines, the limit values
at the installation location will be in accordance with the requirements for the first
environment.
The line filters are suitable for TN and TT supply systems grounded at the neutral point.
2.2.2

Safety information

Connectable networks
Line filters are suitable for direct connection to TN or TT line supplies with grounded neutral
point.
Line filters are designed for connection to systems with a continuous level to voltage
harmonics according to EN 61000-2-4, class 3.
