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 below.)
Use a conductive gasket between the door and the case, as shown in the diagrams below. (Refer
to the diagrams below.)
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 door may warp and gaps may appear between the door and case when screws are tightened.
Be sure that no gaps appear when tightening screws.
