They are divided horizontally by plastic walls and vertically by one screw and three empty holes. "tuv staukstrom" is handwritten in red on the light grey top layer. Below the red writing, on the black plastic middle layer, there is a large white sticker with "Plug to system" printed between upward pointing arrows. At the bottom of the sticker "plug to cable" is printed between two downward pointing arrows. The plug to cable end is made of darker grey plastic.
