Figure 8-7 Connection example for Braking Module Booksize Compact and braking resistor without a thermostatic switch
Note
The digital inputs DI are isolated and are referenced to M_DI (X21.5 and X21.6).
The reference point of the digital outputs DO is the ground GND of the 24 V supply.
It is not permissible that the connections for the temperature switches (X22.1 and X22.2) are
used/assigned for "braking resistor without a thermostatic switch" operation. Otherwise,
malfunctions occur.
