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 10A for 1KVA, 20A for 2KVA, 32A for 3KVA , 40A for 4KVA and 50A for 5KVA. 
• There are two terminal blocks with “IN” and “OUT” markings. Please do NOTmis-connect input and output connectors.
  

WARNING!

• All wiring must be performed by a qualified personnel.    
• It's very important for system safety and efficient operation to use appropriate cable frecommended cable size as below. or AC input connection. To reduce risk of injury, please use the proper recommended cable size as below.

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 3 mm.  
3.Insert AC input wires according to polarities indicated on terminal block and tighten the 
   terminal screws. Be sure to connect PE protective conductor (ground) first.
4.Then, insert AC output wires according to polarities indicated on terminal block and 
   tighten terminal screws. Be sure to connect PE protective conductor
Ground : (yellow-green).
L/  LINE    : (brown or black) cable
        N/  Neutral : (blue) cable
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. 
• 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. If a power shortage occurs and recovers in a short time, it will cause damage to your connected appliances. To prevent this kind of damage, please    check manufacturer of air conditioner if it’s equipped with time-delay function before installation. Otherwise, this inverter/charger will trig overload fault and    cut off output to protect your appliance but sometimes it still causes .
