Maintenance and inspection
Danger
See item
Prohibited
Do not replace parts.
This could be a cause of electric shock, fire and bodily injury. To replace parts, call the lo-
cal sales agency.
14.2
Mandatory
The equipment must be inspected every day.
If the equipment is not inspected and maintained, errors and malfunctions may not be dis-
covered and that could result in accidents.
Before inspection, perform the following steps.
(1) Turn off all input power to the inverter.
(2) Wait for 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 (800VDC or more), and check to make
sure that the voltage to the DC main circuits (across PA-PC) is 45V or less.
If inspection is performed without performing these steps first, it could lead to electric
shock.
