Attentions
When the inverter is powered on, please do not change wiring, connect or detach terminals, otherwise electric
shocks might occur.
Dangers:
1.
Be sure that the power is off before maintenance and inspections. There remains high voltage in the
filter capacitor after powering off, so please go for maintenance and inspection only under the following
conditions:
When the LED indicator on the operation panel is off;
Or when the charging indicator at the bottom right inside the inverter is off;
Or when the bus-bar voltage measured by the multi-meter is no more than 36V after the power is off
for 10 minutes. Otherwise, electric shocks might occur.
2.
Do not modify the inverter by yourself, or there might be risks of electric shocks or injuries.
3.
It is forbidden to leave any wire threads or metal objects inside the inverter during maintenance &
inspections, otherwise a fire can occur.
