Make sure that the DC side and AC side are connected correctly and the DC side
voltage is lower than 850V.
Step 2:
Close AC and DC circuit breaker switches;
Step 3:
Close lightning protection switch KB4, auxiliary power switch KB1, contactor power
switch KB2, (and off-grid integrated model needs to close KB3);
Step 4:
