Line Modules Booksize
3.4 Basic Line Modules with internal air cooling
Booksize power units
238 Manual, (GH2), 06/2008, 6SL3097-2AC00-0BP6
DC link connection and braking resistor connection
100 – 200 kW braking module
Note
After the the DC link voltage has been applied, fault output -X38/5 is "low" for approx.
2 seconds (self test), i.e. in the fault state.
The control unit must suppress this state when switching on the system.

WARNING
The braking module can be connected to the DC link with or without fuses. The connections
between the converter and inverter and braking module must be short-circuit and ground-
fault resistant. The electric strength of the cable must be rated to the line voltage.
Fuses
● Fuses are required for multi-motor systems with a shared DC link (infeed power >>
power of the braking module).
● House-hold type MCBs (1000 V) must be installed in the plus and minus branches.
