The ACBox2000 functions as only the local maintenance isolation switch of the inverter
and turns off when the inverter needs to be maintained to ensure that the inverter is
isolated from the power grid.
If the ACBox2000 is used in a grid-tied PV power system, the system on the AC side
should meet the safety design specifications, such as IEC 60947 and IEC 60364.
It is recommended that the ACBox2000 be installed near the inverter.
