Features:
- Supplies five replacement U-connectors in one package.
- Joins adjacent modules mechanically and electrically.
- Builds the modular backplane-bus path across an S7-1500 or ET 200MP station.
The 6ES7590-0AA00-0AA0 package contains five U-connectors, so the required quantity should be based on the number of adjoining S7-1500 I/O modules.
Seat each connector between the intended modules before the assembly is fixed to the rail; a displaced connector interrupts the self-assembling backplane bus.
After assembly, check that every module is fully latched and that the configured station order matches the physical backplane sequence.
The Siemens 6ES7590-0AA00-0AA0 S7-1500 U-Connector Five-Pack may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Building the backplane path one module boundary at a time
- First boundary: A U-connector links the first pair of adjacent station modules.
- Bus continuation: Each following connector extends the electrical path to the next module.
- Mechanical link: The connector also holds the mating geometry between the two housings.
- Station chain: All installed boundaries together form the modular backplane bus.
Seating the connector before adjoining modules are locked
- Power isolation: Deenergize the station before opening the module chain.
- Connector placement: Fit the U-connector to the documented module side and orientation.
- Module engagement: Slide and lock the adjoining module until the connector is fully seated.
- Final inspection: Check every boundary before restoring power.
Relating one connector fault to downstream module loss
- Local break: A loose connector interrupts the bus at its physical boundary.
- Downstream effect: Modules after that point can disappear from the configured station.
- Visual check: Inspect connector position and module locking before changing software.
- Recovery: Restore full engagement, then confirm the configured hardware order online.
Managing five spare connectors without confusing them with modules
- Quantity: One order number supplies five individual connectors.
- No address: A U-connector has no separate process address or parameter set.
- Storage: Keep unused pieces protected from bent contacts and contamination.
- Issue record: Record which station boundary receives each replacement connector.
