Abstract: In an electrical monitoring panel comprising a grid frame (26,27) having front elements (26,27) disposed at its front side and instrument insets at its rear side, elements of the electric circuitry are arranged inside the front elements.The front elements may be removed from the grid frame whereby the connection with the electric lines and components of the instrument inset is interrupted. The front elements are interconnected by contact elements to permit electric connections in the plane ahead of the grid frame.
