External 24 V power supply
Interface X1 is intended exclusively for the connection of the external 24 V power supply,
e.g.
● SITOP,
● CSM = Control Supply Module (see the Manual SINAMICS S120 Power Units Booksize).
The following power consumption values for the PPU provide a configuration basis for
calculating the 24 V DC power supply.

Requirements of DC power supplies
In the case of supply lines > 10 m, protectors must be installed at the device input in order
to protect against lightning (surge).
The DC power supply must be connected to the ground/shield of the control unit for EMC
and/or functional reasons. For EMC reasons, this connection should only be made at one
point. As a rule, the connection is provided as standard in the PLC I/Os. In exceptional
circumstances when this is not the case, the ground connection should be made on the
grounding rail of the control cabinet; please also refer to /EMC/EMC Installation Guide.
