Check No.10: Power Supply Waveforms Check

Check to see if the power supply waveform is a sine wave (Fig.1)

Check to see if there is waveform disturbance near the zero cross (sections circled in Fig.2)

Sign off on the power supply waveforms check

Warning: Never touch any live parts for at least 10 minutes after turning off the circuit breaker.

If unavoidably necessary to touch a live part, make sure there is no DC voltage using the tester.

Check the continuity with the tester.

Reverse the pins and make sure there is continuity.

Warning: Be sure to wait 10 minutes or more after turning off all power supplies before disassembling work.

Warning: Ventilate when refrigerant leaks during the work. (If refrigerant contacts fire, it will cause to arise toxic gas.)

Caution: Be careful not to get yourself burnt with the pipes and other parts that are heated by the gas welding rod.

Caution: From the viewpoint of global environment protection, do not discharge the refrigerant gas in the atmosphere. Make sure to recover the refrigerant gas with the recovery system.
