Maintenance Safety
Risk of inverter damage or personal injury due to incorrect service!
•
Before maintenance, disconnect the AC circuit breaker on the grid side and
then the DC switch. If a fault that may cause personal injury or device damage
is found before maintenance, disconnect the AC circuit breaker and wait until
the night before operating the DC switch. Otherwise, a fire inside the product or
an explosion may occur, causing personal injuries.
•
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.
