Binding
•
Separate power supply cables and signal cables when wiring.
Control Panel Construction
Openings in the control panel, such as holes for cables, operating panel mounting holes,
and gaps around the door, may allow electromagnetic waves into the panel. To prevent
this from occurring, 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 will be electrically conductive.
•
During assembly, strip the paint off of joint areas (or mask them during painting), to
make them electrically conductive.
•
If gaps appear in the control box case when screws are tightened, make adjustments to
prevent this from occurring.
•
Do not leave any conductive part unconnected.
•
Ground all Units within the case to the case itself.
Door Structure
•
Use a door that is made of metal.
•
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 of 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.
•
Gaps may open between case panels when screws are tightened. Be sure that no
gaps appear when tightening down screws.
