3) Perform discharging by connecting the

 

 

 

 

 

discharging resistance (approx. 100,

terminals of the C10 too 13 (printed as

 

 

 

 

 

“CAUTION HIGH VOLTAGE”) electrolytic

The electrolytic capacitor may not nor-

 

 

Left time:

10 sec. or more

 

 

tents and the voltage may remain. There-

 

 

 

 

 

fore, be sure to discharge the capacitor.

 

 

 

 

 

WARNING

Inverter assembly

 

 

 

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) Remove various lead wires from the

 

 

 

 

 

holder at upper part of the inverter box.

 

 

 

 

 

5) Remove the hook for the partition plate

 

 

 

 

 

(lower left side).

6) Remove the hook for the side cabinet

 

 

 

cabinet (lower left side)

 

 

 

 

 

(lower left side) and the screw, and lift up

 

 

 

 

 

the inverter assembly upward. (ST1T Ø4 x

 

 

 

 

 

10L, 1 pc.) In this time, cut off the band

 

 

 

 

 

bundling each lead wire.

 

 

 

 

 

7) Disconnect connectors of various lead

 

 

 

 

 

wires.

 

Remove the connectors

 

 

 

 

with locking function by

 

 

 

 

pushing the part indicated

 

 

REQUIREMENT

 

by the arrow mark.

 

 

 

 

 

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