A coating means supply device, in particular for a paint facility, having a coating means meter that meters coating means to be applied to application equipment. The coating means supply device includes a coating means reservoir for holding the coating means and for supplying the coating means meter with the coating means. During application of coating material to equipment, the coating means reservoir is at ground potential and is located upstream from the coating means meter, which is at high-voltage potential. The reservoir is connected via an insulating path to the coating means meter. The coating means meter is at ground potential when the coating means reservoir supplies coating means to the coating means meter. Before the coating means meter is returned to a high-voltage potential for continued application of coating material, the insulating path is emptied to again insulate the coating means meter from the coating means reservoir.
