Inverter cover

CAUTION

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

WARNING

The electrolytic capacitor may not nor- mally discharge according to error con- tents and the voltage may remain. There- fore, be sure to discharge the capacitor.
