Maintenance and inspection, and parts replacement
•
Before proceeding to maintenance or inspection, turn OFF the power and wait at least 10 minutes. Make
sure that the charging lamp is turned OFF. Further, make sure, using a multimeter or a similar instrument,
that the DC link bus voltage between the terminals P(+) and N(-) has dropped to the safe level (+25 VDC
or below).
Otherwise, an electric shock could occur.
•
Always carry out the daily and periodic inspections described in the this manual. Use of the inverter for
long periods of time without carrying out regular inspections could result in malfunction or damage, and
an accident or fire could occur.
•
It is recommended that periodic inspections be carryout every one to two years, however, they should
be carried out more frequently depending on the usage conditions.
•
