ACKUP output connection (AC)
To connect the BACKUP output of the inverter, 3 connections are ne-
cessary: ground, neutral and phase.
In any case, connection of the
inverter to ground is mandatory.
Any failure of the inverter when it is not connected to ground through the appropriate terminal (AC
connector) and to the metal frame (external grounding protection) is not covered by the warranty.
