PS CIRCUIT BOARD REPAIR GUIDE
1.
Applicable Circuit Board
This guide is applicable when repairing the circuit board specified in the table 1-1.
Table 1-1

Electrical Performance
2-1
Preparation
• Connect the INLET circuit board (WG970200 for U, A destination or WG970300 for H, B, O
destination) to CN402 and
CN410.
• Adjust the power supply voltage suites each circuit boards. Refer to the table 1-1 above.
• Connect the power cable to the AC inlet of the INLET circuit board.
2-2
Voltages of Each Part
The output voltage is normal if it is within the range specified in the table 2-1 when turning the power on.
Table 2-1
Note: The output voltage may be out of the range if it is measured without the load resistance or the power supply voltage
differs from the specified in the table 1-1.
2-3
Discharge
To prevent the electrical shock (discharge of the electric charge from the capacitor), discharge electricity between the follow-
ing part when handling the PS circuit board.
• Between the positive (+) and negative (-) terminals of C409 and C410. If you have left the unit for 10 minutes or more after
turning the power off, you do not have to discharge.
• Between CN405 and CN409.
• Between CN406 and CN408.
