Backplane connection
The connector links neighboring CPU, signal, function, communication or interface module positions.
Assembly sequence
Begin the connector chain at the CPU and leave the last module without a connector toward the right.
Service replacement
The same spare connector is listed among S7-300 module accessories, including FM 350-2 and SM 331.
Product Overview
6ES7390-0AA00-0AA0 provides the replacement backplane connection used between modules in a SIMATIC S7-300 assembly.
It belongs to the internal module row rather than the sensor and actuator wiring at the front, and is installed as the modules are assembled on the mounting rail.
Key Functions
Continue the internal module chain
The plug-in connector establishes the backplane connection as adjacent S7-300 modules are assembled.
Support the specified rack assembly order
Connectors are fitted beginning at the CPU before the modules are brought together on the rail.
Replace a missing module accessory
The connector is available as an individual spare for compatible S7-300 signal and function module installations.

Frequently Asked Questions
Does 6ES7390-0AA00-0AA0 connect the sensors directly to an S7-300 input module?
No, it is the internal backplane connector, while sensor and actuator field wires connect through the module front connector.
Where should I begin installing 6ES7390-0AA00-0AA0 connectors in a module row?
Start at the CPU and continue through the adjacent signal, function, communication or interface modules.
Should the last module of the assembly receive 6ES7390-0AA00-0AA0?
No, the last module does not receive a bus connector toward the end of the assembly.
Is 6ES7390-0AA00-0AA0 one of the spare connectors for an FM 350-2?
Yes, the connector is included in the FM 350-2 list of S7-300 spare parts.
Can 6ES7390-0AA00-0AA0 be used when assembling an SM 331 analog input module?
Yes, the SM 331 ordering data identifies this bus connector as the corresponding spare accessory.
Will the CPU package normally supply 6ES7390-0AA00-0AA0 for the adjoining joint?
The installation instructions identify the CPU as the exception to the modules that come with a bus connector.
Should I fit 6ES7390-0AA00-0AA0 before bringing neighboring modules together on the rail?
Yes, plug the connectors into the required modules first, then add the modules to the rail and slide each against its neighbor.
