2.5 Motor Modules
The Cabinet Modules are fitted with one SINAMICS S120 Motor Module in the chassis format
and cover the power range from 315 kW to 1500 kW (380 V to 480 V or 500 V to 690 V).
Power ratings up to approximately 5700 kW are possible by connecting units in parallel.
The Motor Modules can also be used as braking module (braking chopper) if a 3-phase
braking resistor is connected instead of a motor.
For more detailed information on this topic, please refer to the SINAMICS Low Voltage
Configuration Manual.

Heat Exchanger Modules

Heat Exchanger Modules are used to dissipate the power loss from the converter. They
comprise a deionized water circuit on the converter side and a raw water circuit on the
plant/system side.
The warm liquid (water and antifreeze and/or inhibitors) in the deionized water circuit of the
converter is pumped to the water/water plate-type heat exchanger using circulating pumps (2
pumps for option W01). The heat exchanger is manufactured out of stainless steel and is
connected to the plant-side raw water circuit.
The liquid in the deionized water circuit on the converter side is cooled by the raw water
circuit on the plant side and flows back to the converter.
Protection against condensation is implemented using a 3-way valve of the internal
deionized water circuit and the intake temperature.
