Immunity requirements
*1 The tests were conducted installed in a control panel.
Installation in a control panel
The installation in the control board ensures safety as well as effective shielding of personal computer-emitted
electromagnetic noise.
■
Control panel
• Use a conductive control panel.
• Mask off the area used for grounding when securing the top or bottom plate to the control panel using bolts.
• To ensure electrical contact between the inner plate and the control panel, mask off the bolt installation areas of an inner
plate so that conductivity can be ensured in the largest possible area.
• Ground the control panel with a thick ground cable so that low impedance can be ensured even at high frequencies.
• Keep the diameter of the holes on the control panel to 10cm or less. If the diameter is larger than 10cm, electromagnetic
wave may be emitted. In addition, because electromagnetic wave leaks through a clearance between the control panel and
its door, reduce the clearance as much as possible. Use of EMI gaskets (sealing the clearance) can suppress undesired
radiated emissions.
The tests by Mitsubishi were conducted using a control panel having the damping characteristics of 37 dB (maximum) and 30
dB (average) (measured at 3 m distance, 30 to 300 MHz).
■
Wiring power and ground cables
Provide a ground point to the control panel near the power of a personal computer. Ground the LG and FG terminals of the
personal computer to the ground point with the thickest and shortest ground cable possible (a thickness at least 2
, a length
of 30cm or shorter).
