MAINTENANCE AND INSPECTION 10.1 Maintenance and Inspection Precautions WARNING * Be sure to turn off the power supply during maintenance and inspection. * After the power supply has been turned off, you must always wait 10 minutes so that DC bus capacitors can discharge then start maintenance and inspection after the CHARGE lamp on the printed-circuit board has gone out. (Immediately after the lamp has gone out, there will be a residual voltage of about 50 V DC in the DC bus intermediate circuit.
Conduct these tests by short-circuiting the terminals as shown below, and by following the conditions described. • In regard to insulation resistance tests, measure the terminals below and the grounding at 500 VDC, and make sure that 5 Megohms or greater is indicated. • Do not perform the withstand voltage test.

Appendix 2 Instantaneous Power Failure Restart and Commercial Power Source Switching 1. Instantaneous power failure restart [Function Outline] This function allows an inverter operation to be selected according to the subject system as follows when an instantaneous power failure occurs.
WARNING l If the retry mode is selected, do not approach the inverter unnecessarily. It will be restarted suddenly after it trips/stops. (Design the inverter so that the safety can be assured even in such a restart.) Otherwise, bodily injury will result. NOTE: Since the retry mode is selected, the equipment restarts for trips of overcurrent, overvoltage, or undervoltage. For undervoltage, 16 retries (17th trip) are executed. For overcurrent or overvoltage, 3 retries (fourth trip) are executed.
