Page 8: Battery Connection
Install the unit by screwing six screws INVERTER INVERTER 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 9: Ac Input/Output Connection
NOTE: Please only use sealed lead acid battery or sealed GEL/AGM lead-acid battery. 3. Insert the ring terminal of battery cable flatly into battery connector of inverter and make sure the bolts are tightened with torque of 2-3 Nm. Make sure polarity at both the battery and the inverter/charge is correctly connected and ring terminals are tightly screwed to the battery terminals. - Page 10 Please follow below steps to implement AC input/output connection: 1. Before making AC input/output connection, be sure to open DC protector or disconnector first. 2. Remove insulation sleeve 10mm for six conductors. And shorten phase L and neutral conductor N 3mm. 3.
- Page 11 PV Connection CAUTION: Before connecting to PV modules, please install separately a DC circuit breaker between inverter and PV modules. WARNING! All wiring must be performed by a qualified personnel. WARNING! It's very important for system safety and efficient operation to use appropriate cable for PV module connection.
