4.2 Measures for Door
(1) Use metal for all members configuring the door.
(2) When joining the door, use a gasket to lower the impedance of the contacting sections, or use a
structure with a large contact area as shown below.
a) Use of gasket
b) Large contact area

•
The EMI gasket or conductive packing must contact a uniform and correct position of the metal
surface.
•
When not using a gasket, ground the control panel grounding with a grounding wire to lower the
door's impedance.
•
Using screws to fix the plates that have been painted (attachment of packing) is the same as
an insulated state. Peel the paint and fix the screws.
