WARNING!
All electrical installations must be carried out in accordance with all
applicable Local and National Codes.
Before connecting the inverter to the grid, approval must be
received by local utility as required by national and state
interconnection regulations.
DANGER!
Danger to life due to high voltages of the PV array
When exposed to sunlight, the PV array generates dangerous DC
voltage which is present in the DC conductors and the live
components which can lead to lethal electric shocks. If you unplug
the terminal plate with the connected DC conductors from the DC-
in slot under load, an electric arc may occur, which will cause an
electric shock and burns.
Ÿ
Do not touch non-insulated conductors.
Ÿ
Do not touch the DC conductors.
Ÿ
Do not touch any live components of the inverter.
WARNING!
Read all of these instructions, cautions, and warnings for the
