Page 7: Battery Connection
Install the unit by screwing three screws. It’s recommended to use M4 or M5 screws. Battery Connection CAUTION: For safety operation and regulation compliance, it’s requested to install a separate DC over-current protector or disconnect device between battery and inverter. It may not be requested to have a disconnect device in some applications, however, it’s still requested to have over-current protection installed. -
Page 8: Ac Input/Output Connection
WARNING: Shock Hazard Installation must be performed with care due to high battery voltage in series. CAUTION!! Do not place anything between the flat part of the inverter terminal and the ring terminal. Otherwise, overheating may occur. CAUTION!! Do not apply antioxidant substance on the terminals before terminals are connected tightly. -
Page 9: Pv Connection
→Ground (yellow-green) L→LINE (brown or black) N→Neutral (blue) 5. Make sure the wires are securely connected. CAUTION: Important Be sure to connect AC wires with correct polarity. If L and N wires are connected reversely, it may cause utility short-circuited when these inverters are worked in parallel operation. CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to restart because it’s required to have enough time to balance refrigerant gas inside of circuits. -
