Danger
Reference
Prohibited
Never replace any part by yourself.
This could be a cause of electric shock, fire and bodily injury. To replace parts, call the local
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
discovered which could lead to accidents.
Before inspection, perform the following steps.
(1) Turn off all input power to the inverter.
(2) Wait at least 15 minutes and check to make sure that the charge lamp is no longer lit.
(3) Use a tester that can measure DC voltage 800VDC or more, and check to make sure
that the voltage to the DC main circuits (between PA/+ and PC/-) is 45V or less.
If inspection is performed without performing these steps first, it could lead to electric shock.
