An electrical voltage supply device for machines processing printing material includes at least one drive motor for the transport of printing material and at least one further electrical consumer. A control unit is provided which, when the supply voltage drops below a minimum acceptable supply voltage of the machine processing printing material, switches of electrical consumers which are not required for the transport of printing material and supplies the drive motor for the transport of printing material from energy stored in the moving masses of the machine processing printing material.

A device for coupling additional equipment to a machine having a control system with inputs and outputs for controlling the machine. The device includes connecting lines connecting the control system and the additional equipment, with the connecting lines coming together at a central connection site. The device can be located at the central connection site for metallically isolating all of the inputs and outputs of the control system from all of the inputs and outputs of the additional equipment.
