The ground point in the maintenance compartment is mainly used for connecting to the
ground cable included in the multi-core AC power cable. For details, see section
Installing AC Output Power
It is recommended that the ground cable be connected to a nearby ground position. For a
system with multiple inverters connected in parallel, connect the ground points of all
inverters to ensure equipotential connections.
