What to do if Siemens FC7xx Control Panel indicates mains failure?
- AAnn PetersonAug 3, 2025
If your Siemens Control Panel indicates a mains failure, it could be due to a mains failure in the public network, in which case no action is required as the emergency power supply is ensured by batteries for at least 12 hours, or up to 72 hours depending on customer specifications. Alternatively, check the fuses in the building's current distributor and replace them if necessary.
