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 >

Remove the inverter cover (plating) by opening four mounting claws.

As shown below, connect the discharge resistance (approx. 100

Ω

40W) or plug of the soldering iron to

voltage b – terminals of the C07 (“

WARNING ELECTRIC SHOCK

” is indicated.) electrolytic

capacitor

(760

F/400V) on P.C. board, and then perform discharging.
