14. Inspection and maintenance
Danger
Mandatory
• The equipment must be inspected every day.
If the equipment is not inspected and maintained, errors and malfunctions may not be discovered
which could lead to accidents.
• Before inspection, perform the following steps.
(1) Shut off all input power to the inverter.
(2) Wait at least ten minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltages (800V DC or more), and check that the voltage to the
DC main circuits (across PA/+ and PC/-) does not exceed 45V.
Performing an inspection without carrying out these steps first could lead to electric shock.
Be sure to inspect the inverter regularly and periodically to prevent it from breaking down because of the environment
of use, such as temperature, humidity, dust and vibration, or deterioration of its components with aging.
14.1 Regular inspection
Since electronic parts are susceptible to heat, install the inverter in a cool, well-ventilated and dust-free place.
This is essential for increasing the service life.
The purpose of regular inspections is to maintain the correct environment of use and to find any sign of failure or
malfunction by comparing current operation data with past operation records.
