Toshiba RAV-SM801BT-E, RAV-SM1400AT-E Requirement, Detachment, Part name, Procedure, Remarks

No.	Part name			Procedure
ƒ Inverter		1.	Detachment
	assembly	1)	Perform work of item 1 of •.
		2)	Take off screws of the upper part of the
			front cabinet.
			•	If removing the inverter cover under this
				condition, P.C. board can be checked.
			•	If there is no space in the upper part of
				the upper cabinet, perform work of ‚.

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.

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.

WARNING

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.

4)Take off screws (ST1T Ø4 x 10L, 2 pcs.) fixing the main body and the inverter box.

5)Remove various lead wires from the holder at upper part of the inverter box and wiring holder at right side of the terminal block.

6)Remove the lead wire from the bundled part at left side of the terminal block.

7)Pull the inverter box upward.

8)Disconnect connectors of various lead wires.

REQUIREMENT

As each connector has a lock mechanism, avoid to remove the connector by holding the lead wire, but by holding the connector.
