IMPORTANT! In order to improve the corrosion resistance of the grounding terminal,
we recommend that the external grounding terminal is coated with silica gel or zinc
paint for protection after installation of the grounding cable.
6.3 AC Connection (grid connection)
DANGER! Never connect or disconnect the connectors under load.
NOTICE! The AC connection to the electrical distribution grid must be performed
only after receiving authorization from the utility that operates the grid.
WARNING! An overcurrent protection device (OCPD) must be used between the
inverter and the grid.
The AC cable used must be dimensioned in accordance with any local and national directives on
cable dimensions which specify requirements for the minimum conductor cross-section. Cable
dimensioning factors are e.g.: nominal AC current, type of cable, type of routing, cable bundling,
ambient temperature and maximum specified line losses.
We recommend 35-185 mm
