The invention concerns a method and arrangement for disconnecting consumers who are connected to a voltage source, specially a direct voltage source. For the purposes of the present invention direct voltage systems are, for instance, the well-known mobile equipment driven by solar cells, primary or secondary batteries. The present invention is based on the knowledge that several consumers are often present in a voltage system, apart of which can be disconnected immediately when one or several conditions for disconnection are fulfilled, while another part of the consumers should be gradually disconnected due to technical safety reasons or psychological aspects. According to the invention consumers connected to a voltage source can be disconnected in two steps, that is, the power passing through the consumers is reduced, for which a slow regulation is offered, and later the power passing through the rest of the users is disconnected. The invention also concerns a circuitry to carry out the invented method, which has a controllable resistance element (M2) to disconnect least one first consumer (V) and a controllable connecting element (M1) to distconnect at least one further consumer (V1), which are controlled by a regulating circuit. The regulating circuit is designed in such a way that it is only after the power is flowing through the first consumer (V) that the power of the other consumer (V1) can be disconnected.
