40.4.2 Measures for Door

 Use metal for all members configuring the panel.

 When joining the door, use a gasket to lower the impedance of the contacting sections, or use a structure with a large con-

tact area as shown below.

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

Use of gasket

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

(2) 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.

 Shield the power supply section and insert a filter to prevent the noise from flowing in or out.

Selection of the noise filter capacity will differ according to the drive unit and devices being used.

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

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