Hi tigranes-97, No, the BACK-UP BATTERY 3.6V/2.3AH F. PS405/407 is only for S7-400 CPUs respectively their power supplies. For S7-300 PLCs the Backup Battery 3.6V/min. 0.85Ah f.S7-300 is used, but only for the older PLCs with Memory Card, not Micro Memory Card. Have a look at 'What are the order numbers of the backup batteries for the various CPUs?'. Kind regards |
