Maintenance

Danger

！

●

Maintenance should be done by professional maintenance technical person.

●

Please ensure that AC side breakers should be turned off firstly, then DC side

breakers should be turned off before checking and maintaining, after waiting at least

5 minutes, should measure DC side and AC side voltage with a voltage meter, to

ensure that operation under the circumstance of no voltage between DC side and AC

side.
