How to Discharge the E.Capacitor on E.Capacitor P.C.B.
• This unit equipped with two pieces of capacitors as E.Capacitor.
“Either one of the E.Capacitor discharging operation” makes discharging for others as well.
CAUTION:
•
Be sure to discharge the E.Capacitors on E.Capacitor P.C.B. before disassembling.
•
Be careful of the high voltage circuit on E.Capacitor P.C.B. when servicing.
[Discharging Procedure]
1. Remove the Front Unit.
2. Put the insulation tube on the lead part of resistor (ERG5SJ102:1k
Ω
/5W).
(An equivalent type of resistor may be used.)
3. Put the resistor between both terminals of E.Capacitor on the E.Capacitor P.C.B. for approx. 5 seconds.
4. After discharging, confirm that the E.Capacitor voltage is lower than 10V by using a voltmeter.
