Basic Line Modules with internal air cooling

Description

The Basic Line Modules provide an unregulated DC link voltage that matches the rectified
line input voltage.
One or more Motor Modules can be connected to the power supply network via the Basic
Line Module. The Basic Line Module provides the DC link voltage for the Motor Modules.
To reduce the energy (e.g. for emergency retraction), a controller for an external braking
resistor has been integrated in the 20 kW and 40 kW Basic Line Modules. An external
Braking Module must be used for 100 kW Basic Line Modules.
The Basic Line Module is suitable for direct operation on TN, IT, and TT systems.
The 100 kW Basic Line Module includes a basic interference suppression, but the 20 kW
and 40 kW Basic Line Modules do not include it.
The ratio of line short-circuit power to rated power must be ≥ 30.
The maximum total cable length for 20 kW and 40 kW Basic Line Modules (interference
voltage category C2) is 350 m (shielded) with an upstream EMC filter (see Possible Line
Reactor and Line Filter Combinations chapter)
500 m shielded and 750 m unshielded if the limit values are not observed.
The maximum total cable length for 100 kW Basic Line Modules (interference voltage
category C2) is 350 m (shielded) with an upstream EMC filter and the same without an
EMC filter for interference voltage category C3 (or 500 m shielded and 750 m unshielded if
the limit values are not observed)

Safety information

Risk of electric shock. Dangerous voltages are still present for up to 5 minutes after the
power supply has been switched off. The protective cover must not be opened until this
time has elapsed.
When opening the protective cover for the DC link, you must activate the release.
A suitable tool (e.g. screwdriver) must be used for this purpose.
The components must only be operated when the protective cover of the DC link is closed.
Damaged components must not be used further, as this could result in secondary damage
or accidents.
