Summary:An interface (IMT) for interruption-free power supply (UPS) which is provided in particular for a data processing system having at least one computer (PC) and has a storage battery (accumulator) for providing the power during a mains failure. The power supply (UPS) has an input for disconnecting the power supply, a first output for reporting a mains failure and a second output for reporting the fact that the charge state of the storage battery has fallen below a predetermined charge state. The said input and outputs are connected to the interface (IMT). Furthermore, the interface (IMT) is connected to at least one computer. The interface (IMT) has outputs for reporting to the computers (PC) a mains failure and outputs for reporting to the computers (PC) the fact that the charge state of the storage battery of the power supply (UPS) has fallen below the predetermined charge state. Furthermore, the interface (IMT) has inputs for establishing a predetermined operating state of a respectively connected computer (PC) and inputs for establishing whether or not a respectively connected computer is in operation. The interface (IMT) outputs a signal at the output connected to the input for disconnecting the power supply (UPS) in each case only when a signal is present at each relevant input of the interface (IMT) corresponding to a computer (PC) which is in operation, by means of which signal the relevant computer (PC) which is in operation...
