Warning
In the power-on state, please do not touch the inverter terminals;
otherwise, there exists the risk of electric shock.
If cover is to be removed, the power supply must be disconnected
first.
Wait for at least 10 minutes after power off or confirm that the
CHARGE indicator is off before maintenance and inspection to
prevent the harm caused by the residual voltage of the main
circuit electrolytic capacitor to persons.
The components shall be maintained, inspected or replaced by
qualified electricians.
Caution
The circuit boards have large scale CMOS IC. Please do not
touch the board to avoid the circuit board damage caused by
static electricity.
