K Precautions when inspecting the control section of the outdoor unit
NOTE :
A large-capacity electrolytic capacitor is used in the outdoor unit controller (inverter). Therefore, if the power
supply is turned off, charge (charging voltage DC280 to 380V) remains and discharging takes a lot of time.
After turning off the power source, if touching the charging section before discharging, an electrical shock may
be caused. Discharge the electrolytic capacitor completely by using soldering iron, etc.
< Discharging method >
1. Remove the inverter cover (plating) by opening four mounting claws.
2. As shown below, connect the discharge resistance (approx. 100Ω4 0W) or plug of the soldering iron to
voltage between + – terminals of the C09, C10 ("WARNING ELECTRIC SHOCK" is indicated.)
electrolytic capacitor (760µF/400V) on P.C. board, and then perform discharging.
