S7-400 System Application
The PS 407 is part of the S7-400 rack power architecture. It provides the supply required by the rack and the automation modules installed in the system.
System Role
The power supply supports the S7-400 rack by providing the DC rails required by the installed control-system modules.
Maintenance & Downtime Context
Maintenance teams may search for this module when an S7-400 rack develops a power-supply fault, loses a required DC rail or reports repeated supply-related alarms. If rack power cannot be maintained, CPU and I/O operation may be interrupted, potentially stopping the controlled process.
Installation & Power Connection
Installation and power connection should follow the Siemens S7-400 installation instructions and the electrical requirements of the application.
Installation Preparation
- Confirm the designated S7-400 rack arrangement.
- Follow the system documentation for mounting, wiring and commissioning.
- Use the specified cable construction for the mains connection.
- Observe the protective conductor and electrical safety requirements.
Supply Connection
- The manufacturer specifies an AC power plug for connection to an AC or DC supply.
- For DC operation, follow the prescribed connection instructions in the installation manual.
- Observe the documented polarity and connection procedure before energizing the module.
Status Indication & Fault Checks
Front-panel indicators provide information about internal module status, output supply status and backup battery conditions.
Front-Panel Indicators
- INTF — internal module fault indication
- DC 5 V — 5 V output status
- DC 24 V — 24 V output status
- BAF — backup battery fault indication
- BATT1F / BATT2F — battery fault indications
Fault Investigation
- Check the relevant output and fault LEDs.
- Review the connected load if the manual indicates an overload or short-circuit condition.
- Check battery condition when backup-related indicators are active.
- Use the manufacturer's LED fault tables before resetting or replacing the module.
