(5) Disposal Dispose as a general industrial waste. (6) Others The pictures in this operation and installation manual occasionally drop the cover or breaker in order to explain in detail, however, you must strictly follow the guidelines in this manual for operation after installing the cover and breaker.
Confirm all setting values prior to operation 2. Product 2.1 General 2.1.1 Contents you should know before using the appliance If you misuse the inverter, it is operated abnormally or its performance may be depreciated. As the inverter might be broken or damage might impair the body seriously, use the inverter after understanding the application or installation manual enough in using the inverter.
