Abstract
A coating material supply device is disclosed, such as for a paint facility. An exemplary coating material supply device may include a coating material reservoir and a coating material meter. During application of coating material, the coating material reservoir may be at ground potential and may be located upstream from the coating material meter, which may be at a high-voltage potential. The reservoir may be connected via an insulating path to the coating material meter. The coating material meter may be at ground potential when the coating material reservoir supplies coating material to the coating material meter. Before the coating material meter is returned to a high-voltage potential for continued application of coating material, the insulating path may be emptied to insulate the coating material meter from the coating material reservoir.
