System Design
Door Structure
• Use a metal door.
• Use a water-draining structure where the door and case fit together, and leave no gaps. (Refer to
the diagrams on the next page.)
• Use a conductive gasket between the door and the case. (Refer to the diagrams on the next page.)
• Strip the paint off the sections of the door and case that will be in contact with the conductive
gasket (or mask them during painting), so that they will be electrically conductive.
• The panel may warp and gaps may appear when screws are tightened. Be sure that no gaps
appear when tightening screws.
