Consult section "Important safety instructions" and the following instructions before working on the unit.

9.1. Safety instructions for the DC connection

DANGER
Make sure there is no voltage present on the unit before starting the connection.
Do not switch on the power to the unit until you have successfully made the rest of the connections and the unit
is closed.
Use the Personal Protective Equipment specified in section "Personal Protective Equipment (PPE)".
While connecting the inverter, make sure of the proper installation of the cables on the unit´s terminals so that
parts of accessible wires do not remain live.
