Connection to the Power Grid
The ports for the Power grid connection cables are located either on the cabinet side
or base.
If the distance between the inverter and the Grid connection point requires the use of a
greater cable section, then the use of an external distribution box, located close to the
inverter, is compulsory in order to change from one section to another.
The cable section shall always be based on the equipment power rating.
The inverter protections at the grid connection support a short-circuit current of up to
70 kAmp.
Prior to any manipulation, check that there is no electrical hazard at the power
input from the grid.
The use of safety gloves and glasses homologued for electrical risk is compulsory to
ensure lack of voltage.
These models are equipped with a three terminal bi-metal connector (three phases with
neutral) for connection to the power grid.
The maximum permitted section for these terminals is 50 mm
