3.2.4  Special features of the SINAMICS S120 Training Case 
Basic procedure 
The devices are designed for use with the 230 V AC power supply, so you must change the 
setting for the device connection voltage of the motor modules if you are using the 
SINAMICS S120 Training Case. 
To change the setting, follow these steps: 
1. Select the respective drive in S7T Config. 
2. In the context menu, select the Experts > Expert List command. 
3. There you change the following parameters: 
–  "p210 device supply voltage" to the value "400 V" 
–  "p1248" to "244" 
Note 
The motor modules integrated into the training case were adapted at the factory for 
the 230 V AC connection voltage up to order number MLFB 6SL3120 - xTE13 - 0AA2, 
so they cannot be replaced. 
With SINAMICS firmware version V2.5 SP1 x x and higher, it is possible to replace 
motor modules but only in conjunction with motor modules with DAC processors 
(order number MLFB 6SL3120 - xTE13 - 0AA3 and higher). The configuration settings 
to change the connection voltage to 230 V AC are done in the expert list for the motor 
module. If the training case you are using has motor modules with DAC processors 
(MLFB 6SL3120 - xTE13 - 0AA3 and higher), make sure you read the following
