[2] Control Box of the Outdoor Unit
1) Exercise caution not to damage the bottom and the front panel of the control box. Damage to these parts affect the water-
proof and dust proof properties of the control box and may result in damage to its internal components.
2) Faston terminals have a locking function. Make sure the cable heads are securely locked in place. Press the tab on the ter-
minals to remove them.
<HIGH VOLTAGE WARNING>
Control box houses high-voltage parts.
When opening or closing the front panel of the control box, do not let it come into contact with any of
the internal components.
Before inspecting the inside of the control box, turn off the power, keep the unit off for at least 10 minutes,
and confirm that the voltage between FT-P and FT-N on INV Board has dropped to DC20V or less.
(It takes about 10 minutes to discharge electricity after the power supply is turned off.)
