*1 The module is an open-type device and must be placed in a conductive control panel or similar type of enclosure. The tests were
conducted with the module installed in a control panel.
*2 The accuracy of an analog-digital converter module may temporarily vary within 10%.
Installation in a control panel
The module is an open-type device and must be installed inside a conductive control panel.
Installing the module inside the control panel ensures safety as well as effective shielding of electromagnetic noise emitted
from the module.
■Control panel
• Use a conductive control panel.
• When securing the top or bottom plate using bolts, cover the grounding part on the control panel so that the part will not be
painted.
• To ensure electrical contact between inner plates and the control panel, mask off the bolt installation areas of each inner
plate so that conductivity can be ensured in the largest 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 leak. In addition, because electromagnetic wave leaks through a clearance between the control panel and its
door, reduce the clearance as much as possible. The leakage of radio waves can be suppressed by directly applying an
EMI gasket on the paint surface.
The tests were conducted by Mitsubishi Electric Corporation using a control panel having damping characteristics of 37dB
(maximum) and 30dB (average) (measured at 3m distance, 30 to 300MHz).
■Power cable and ground cable
• Near the power supply part, provide a ground point to the control panel. Ground the FG terminal with the thickest and
shortest possible ground cable (2, 30cm or shorter).
