• Connect to the case all Units inside of the case.
D Door Structure
• Construct the door of metal.
• Use a water draining structure where the door and case fit together, and leave no gaps. (Refer to the
diagrams below.)
• Use conductive packing between the door and the case, as shown in the diagrams below. Strip the
paint off of the sections of the door and case that will be in contact with the conductive packing (or mask
them during painting), so that they will be electrically conductive.
• Be careful not to let gaps be opened in the control box while tightening down screws.
