FAQ
How many power supplies are needed per rack? One power supply module is required per rack; with current-transfer interfaces, the central controller supply also powers expansion units.
Is the backup battery included? No, the battery must be ordered separately; two batteries are recommended for 10 A power supplies.
What is the difference between PS405 and PS407? The PS405 accepts DC input (24/48/60 V DC); the PS407 accepts AC input (85-264 V AC).
Installation Guide
Switch off the rack power supply before installation.
Insert the module into the leftmost slots (1 to 3) of the S7-400 rack.
Connect the DC input voltage to the supply terminals.
Install the backup battery if required for power failure buffering.
Switch on the power supply and verify the 5 V DC LED illuminates.
Selection Tips
Select the PS405 for DC-powered S7-400 installations; choose PS407 for AC-powered racks.
Calculate total backplane load: 10 A at 5 V DC supports fully loaded 16-slot racks.
For extreme environments, consider the SIPLUS variant 6AG1405-0KA02-2AA0 rated for -25 to +60 °C.
