09.
Checking power supply voltage within allowed working range before
usage, otherwise, it need to change voltage or custom special voltage inverter.
10.
When inverter usage site altitude over1000 meters, inverter should
decrease current to use, output current decrease about 10% of rated current
per 1000 meters increase.
11.
Motor should do insulation check before first usage or reusage after lay
aside for long time. Checking method show as graph 1-1 below with 500V
voltage type megohm meter, insulation resistance should not smaller than 5
MΩ, otherwise inverter maybe damaged.
12.
Forbid inverter output side to assemble capacitor to improve power
factor or anti-thunder dependent resistor etc, otherwise it may cause inverter
fault trip or component damage show as graph 1-2.

1.4. Scraping handling notice
Notices when handling with scrapped inverter and components:
01.
The unit: dispose the inverter as industrial waste.
02.
Electrolytic capacitor: It may cause explosion when electrolytic capacitor
under burning.
03.
Plastic: it may result in harmful and poisonous gas when plastic and
rubber of inverter burning, and safeguard preparations should be taken
before burning.
