Page 7: Battery Connection
Battery Connection CAUTION: For safe operation and regulation compliance, it's required to install a separate DC over-current protector or isolator between battery and inverter. It may not be required to have a battery isolator in some applications, however, it's still required to have an over-current protection installed. - Page 8 3. Insert the cable lugs of battery cable flatly into the M6 battery connector of the inverter and make sure the nuts are tightened with a torque of 2-3 Nm. Making sure polarity at both the battery/battery isolator and the inverter is correctly connected. WARNING: Shock Hazard Installation must be performed with care due to high battery voltage in series.

Page 9: Ac Input/ Output Connection
AC Input / Output Connection CAUTION!! Before connecting to AC input power source, please install a separate AC breaker between inverter and AC input power source. This will ensure the inverter can be securely disconnected during maintenance and fully protected from over current of AC input. The recommended spec of AC breaker is 40A for 4KVA and 50A for 5KVA. -

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 AC 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. - Page 11 3.
