XCAUTIONX
Inverter cover
Be careful to check the inverter because
high-voltage circuit is incorporated in it.
3) Perform discharging by connecting + , –
polarities by discharging resistance
(approx. 100Ω, 40W) or plug of soldering
iron to + , – terminals of the C14 (printed
as “CAUTION HIGH VOLTAGE”) electrolytic
capacitor (500µF) of P.C. board.
Cord clamp
X WARNINGX
The electrolytic capacitor may not normally
discharge according to error contents and
the voltage may remain. Therefore, be sure
to discharge the capacitor.
Screws
X WARNINGX
For discharging, never use a screwdriver and
others for short-circuiting between + and
– electrodes. As the electrolytic capacitor is
one with a large capacity, it is very dangerous
because a large electric spark will occur.
