·The smoothing capacitor is charged at a voltage of about 264 to 358 V across it.
·
For an energization check of each part of the circuit of the outdoor electrical parts, the power circuit is energized
as well. Therefore take enough care when doing work.
1.Power switch is turned OFF.
2.After turning off the power supply, wait for at least 15 minutes, unlid the electrical parts,apply a soldering
iron of 30 to 75 W at the positive and negative terminals of IPM, and discharge the charge voltage of the
smoothing capacitor.
Warning
Cautions
Do not use a soldering iron equipped with a
transformer.Any such practice would blow
out the temperature fuse in the transformer.
As shown in the left-hand figure, apply a soldering iron to the
positive and negative terminals of IPM and discharge the
discharge voltage of the smoothing capacitor.
