Page 19: Ac Output Connection
AC Output Connection CAUTION ·It's forbidden that several inverters shares an AC switch. ·It's forbidden to connect with load between inverter and AC switch. To ensure the inverter can be disconnected with load safely, we suggest equipping independent dipolar switch (as below) for each inverter to protect the inverter. Model AC input specification (GRID) AC output specification (BACKUP) - Page 20 Step3 Unscrew the lock nut, lead the live wire, neutral wire go through the lock nut, and then connect them to the corresponding port of AC terminal (draw the live wire and neutral wire connected to grid through the two magnetic rings). Step4 Tighten terminals one by one with tool of screwdriver.
