• The ground connection of the external protective earth terminal is not a substitute for the connection of the PE terminal in the AC wiring, but must ensure that both are reliably grounded. Otherwise, HYXiPOWER will not take any responsibility for the possible consequences. 5.3.1 External Grounding Requirements In the PV power generation system, all non-current-carrying metal parts and equipment housings should be grounded (e.g. -
Page 25: Grounding Procedure
5. Electrical Connection Three-Phase String Inverter The external grounding terminal of a single inverter should be grounded near the end. When there are multiple inverters, the external grounding terminals of all inverters and the grounding points of PV mounts should be connected to the equipotential line (depending on the site conditions) to ensure that the external grounding of all inverters is grounded. - Page 26 An independent two-pole circuit breaker must be installed on the output side of the inverter to ensure safe disconnection from the grid.
