(4) External power supply
Use a CE-marked product for an external power supply and always ground the FG terminal.
(External power supply used for the tests conducted by Mitsubishi: TDK-Lambda DLP-120-24-1, IDEC PS5R-
SF24)

(5) Power supply part
Always ground the LG and FG terminals after shunting them.
(6) Other measures
(a) Ferrite core
A ferrite core has the effect of reducing radiated noise in the 30MHz to 100MHz band.
It is recommended to attach ferrite cores if shield cables coming out from pulled out of the control panel do not
provide sufficient shielding effects.
Note that the ferrite cores must be attached at the position closest to the cable hole inside the control panel. If
attached at an improper position, the ferrite core will not produce any effect.
Attach a ferrite core to each power line as illustrated below.

Example
(b) Noise filter (power supply line filter)
A noise filter is a component which has an effect on conducted noise.
Attaching the filter can suppress more noise. (The noise filter has the effect of reducing conducted noise of 10
MHz or less.)
The precautions for attaching a noise filter are described below.

The precautions for attaching a noise filter are described below.
• Do not bundle the cables on the input side and output side of the noise filter. If bundled, the output side
noise will be induced into the input side cables from which the noise was filtered.
• Ground the noise filter grounding terminal to the control panel with the shortest cable possible (approx.
10cm).
