The brake cannot be directly connected to the Motor Module in the chassis format. The
connection terminals are only designed for 24 VDC with 150 mA; the Safe Brake Adapter is
required for higher currents and voltages.
Note
Additionally required hardware for other formats
A Safe Brake Relay is also required for the "Safe Brake Control" in the blocksize format. A Safe
Brake Adapter is required in the chassis format (starting with order numbers with the
ending ...xxx3). The Safe Brake Adapter is available for a 230 V AC brake control voltage.
