1.MEASURE CARRIED OUT TO IMPROVE THE HEAT RESISTANCE
OF THE DC PWB.
2.MEASURE CARRIED OUT TO PREVENT LEAKING.
1. Measure carried out to improve the heat resistance of the DC PWB.
1.Model Name: SF-2020/1020/2120/1120
2.General: The changes described below have been carried out in the DC PWB of the models
listed above.
1) An increase in the capacity of the aluminium electrolytic capacitor has been carried
out as a measure to minimize the voltage fluctuation caused by the load fluctuation
which occurs when a power reduction occurs in the input power supply.
2) Changes and additions of parts were carried out, including the cooling plate. This
change was carried out as a measure to improve the heat resistance of the PWB to
compensate for the rise in temperature of the terminals.

2. Measure carried out to prevent leaking.
1.Model Name: SF-2116/1016/2118/1018/2020/1020/2120/1120
2.General: A change has been carried out in the high voltage harness of the drive unit. This action
has been carried out as a measure to prevent leaking in the models listed above.
Furthermore, in accordance with this change the part code of the drive frame has also
been changed, but the part code due to skating is different.
3.Action: SF-2020/1020/2120/1120: From 1997 March production.
SF-2116/1016/2118/1018: Running change from 1997 March production.
