In an installation including a stored energy source and an electric motor which can be fed by an inverter, and a method for operating an installation, the stored energy source forms an electrical series circuit with a first fuse and further fuse(s). A controllable contact, e.g., a switch, a contactor, etc., is connected in parallel to the further fuse, or a respective controllable contact, e.g., a switch, a contactor, etc., is connected in parallel to each of the further fuses. The series circuit feeds the DC-voltage-side connection of the inverter, and a device for detecting the voltage applied to the series circuit is connected to control electronics which generate a control signal for the contact or control signals for the controllable contacts. For example, the respective contact is opened when the voltage falls below a respective voltage threshold.
