X21/X22 Ep Terminals / Temperature Sensor Motor Module - Siemens SINAMICS S120 Combi User Manual

Note
The motor brake must be connected via connector X11 on Single Motor Modules, and X11
and X12 on Double Motor Modules. The BR- cable must not be connected directly to
electronics ground (M).
Only protective extra-low voltages (DVC A) that comply with EN 60204-1 must be
connected to all connections and terminals between 0 and 48 V DC.
The voltage tolerances of the motor holding brakes (24 V ± 10 %) must be taken into
account.
