Openings in the control panel, such as holes for cables, panel mounting holes, and gaps around the
door, may allow electromagnetic waves into the panel. To prevent this, observe the recommendations
described below when designing or selecting a control panel.
Case Structure
• Use a metal control panel with welded joints at the top, bottom, and sides so that the surfaces are
electrically conductive.
• If assembly is required, strip the paint off the joint areas (or mask them during painting), to make
them electrically conductive.
• The panel may warp and gaps may appear when screws are tightened. Be sure that no gaps
appear when tightening screws.
• Do not leave any conductive part unconnected.
• Ground all units within the case to the case itself.
