Typical 24 V Current Consumption Of The Components - Siemens SINAMICS S120 System Manual

Cabinet design and EMC
12.3 24 V DC supply voltage
Using the 24 V connector
• A 24 V connector should be inserted onto the 24 V busbar between each Active Line Module
Booksize, HF Motor Module, HF Choke Module, HF Damping Module and DC link component.
• Attachment and removal are only permissible in a de-energized state.
• A maximum of 5 unplugging and plugging cycles is permissible.
Note
The 24 V connectors must be attached before the drive line-up is commissioned.

Typical 24 V current consumption of the components

A separate 24 V power supply must be used for the SINAMICS S120 drive line-up.
The following table can be used to calculate the 24 V DC power supply. The values for typical
current consumption are used as a basis for configuration.
