assembly
Be careful to check the inverter because
high-voltage circuit is incorporated in it.
Be careful to discharge the capacitor
because the electrolytic capacitor cannot
naturally discharge and voltage remains
according to trouble type in some cases.
This capacitor i one with mass capacity.
Therefore, it is dangerous that a large
spark generates if short-circuiting
between
etc. for discharging.
As each connector has a lock mecha-
nism, avoid to remove the connector by
holding the lead wire, but by holding the
connector.
Procedure
1) Perform work of items 1. of
2) Remove screw (ST1TØ4 × 8L 1 pc.) of the
upper part of the front cabinet.
• If removing the inverter cover in this
condition, P .C. board can be checked.
• If there is no space in the upper part of
the upper cabinet, perform work of
3) Perform discharging by connecting
polarity by discharging resistance (approx.
100Ω, 40W) or plug of soldering iron to
terminals of the C15 (printed "CAUTION
HIGH VOLTAGE" is attached.) electrolytic
capacitor (500µF) on P .C. board.
NOTE

4) Remove screw (ST1TØ4 × 8L 1 pc.) 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.
