MAINTENANCE AND INSPECTION
Chap 7
Perform daily and periodic inspections to avoid trouble and keep reliable operation of the inverter for a long time.
When performing inspections, follow the instructions given in this chapter.
Carry out inspection after waiting 5 minutes or longer for units of FRN0115G2S-2G / FRN0060G2-4G
or lower, or 10 minutes or longer for units of FRN0146G2S-2G / FRN0075G2-4G or higher.
Furthermore, ensure that the LED monitor or charge lamp are OFF, and use a device such as a tester to
ensure that the DC intermediate circuit voltage across main circuit terminals P(+) and N(-) has dropped to a
safe level (+25 VDC or less).
Failure to observe this could result in electric shock.
Maintenance and inspection, and part replacement should only be carried out by the authorized personnel.
Remove all metal objects (watches, rings, etc.) before beginning work.
Be sure to use insulated tools.
