The power supplies supply the S7-400 modules with their 5 V DC operating voltages via the backplane bus. Power supplies are available for AC line voltages of 85 to 264 V and for DC voltages of 19.2 to 300 V. One power supply module is required per rack. The power supply modules are inserted at the far left in the rack (starting from slot 1).
Depending on the version, they occupy slots 1 to 3. The modules are enclosed and are cooled via natural convection. The back-up battery is optional and must be ordered in addition. For power supplies at and above 10 A, two back-up batteries are recommended.
