Hello, You need to read chapter 3 "Power Supply Module"of the following manual: SIMATIC S7-400 S7-400 Automation System Module Data and section 3.4 "operator controls and indicators" for more information. Best regards Hamid Hosseini |

According to me no it is not possible. About the new batteriesWhy is a battery fault signaled when you insert a back-up battery, even though the battery is new? Best regards, Hristo Mihalev
