WARNING!
The inverter cover must be opened only after shutting off the inverter ON/OFF switch located at the
bottom of the inverter. This disables the DC voltage inside the inverter. Wait five minutes before
opening the cover. Otherwise, there is a risk of electric shock from energy stored in the capacitors.
WARNING!
Do not remove the StorEdge Interface cover before five minutes have elapsed after disconnecting all
sources of power, and shutting OFF the inverter and the StorEdge Interface.
WARNING!
Before operating the system, ensure that the power cable and wall outlet have been grounded properly.
WARNING!
When handling the battery, adhere to all manufacturer safety instructions.
