COPIER : SF-2120
No. : S-206
MEASURE TO COMPLY WITH EMI (ELECTRICAL NOISE) STANDARDS.
1.Model Name: SF-2020/2120/1020/1120 (only for machines bound for the Taiwan market)
2.General: EMI (electrical noise) standards have been put in effect in Taiwan as of 1997 January.
In accordance with this market development, the changes described below have been
carried out.
1) The addition of leak prevention sheets A, B and C to the drive frame has been carried
out as a measure to prevent leaking from the high voltage lines.

2) The addition of a leak prevention sheet to the rear cabinet has been carried out as a
measure to prevent leaking from the high voltage lines.
Leak prevention sheet D (PSHEZ4463FCZZ)
Back side of the rear cabinet
3) The addition of gaskets A and B and the addition of gasket attachment sheets have
been carried out as a measure to reinforce the grounding performance of the 2nd base
plate unit upper and lower.
• Gasket A and gasket attachment sheet.

5) The input capacitor (C204) of the AC PWB has been changed from 0.22 µF to .6 µF.
In accordance with this change, the surge arrestor (A201) and the cement resistors
(R201) have been discontinued. Furthermore, the electrical discharge resistors (R203)
have been changed from 1 MΩ to 200 KΩ.
As a result of these changes we have set a new AC PWB for the Taiwan version.
Discontinued
3.Action: From 1996 April production.
