Fault
1. When the fault occurs, it is forbidden to directly
disconnect the DC switch and unplug PV termi-
nals when the direct current is greater than 0.5 A;
2. Wait until the direct current of the inverter falls
below 0.5 A, then disconnect the DC switch and
unplug the faulty strings;
3. Do not reinsert the faulty strings before the
grounding fault is cleared;

9.2 Maintenance
9.2.1 Maintenance Notices
Risk of inverter damage or personal injury due to incorrect service!
• Be sure to use special insulation tools when perform high-voltage operations.
• Before any service work, first disconnect the grid-side AC circuit breaker and
check the inverter status. If the inverter indicator is off, please wait until night to
disconnect the DC switch. If the inverter indicator is on, directly disconnect the
DC switch.
• Turn the DC switch from ON to OFF and continue to turn it 20 degrees counter-
clockwise, the DC switch can be locked here.
（ For countries “AU” and “NZ” ）
• After the inverter is powered off for 5 minutes, measure the voltage and current
with professional instrument. Only when there is no voltage nor current can op-
erators who wear protective equipment operate and maintain the inverter
• Even if the inverter is shut down, it may still be hot and cause burns. Wear pro-
tective gloves before operating the inverter after it cools down.
