41.4.2 Measures for Door

(1) Use metal for all members configuring the panel.

(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.

(3) The EMI gasket or conductive packing must contact the metal surface uniformly and at the correct position.

Use of gasket

(Note 1) When not using a gasket, ground the control panel grounding with a grounding wire to lower the door's

(Note 2) Using screws to fix the plates that have been painted (attachment of packing) is the same as an insulated

state. Remove the paint and fix the screws.

(1) Shield the power supply section and insert a filter to prevent the noise from flowing in or out. Selection of the noise

filter capacity varies depending on the drive unit and devices to be used.

(Note 1) The conductive noise can be suppressed by inserting a noise filter, but the radiated noise will flow out.

(Note 2) The conductive and radiated noise can both be suppressed by adding a partition plate to the noise filter.
