5.5 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 PDA1500-STATION,
32 A for PDA3000-STATION.
Caution!!
There are two terminal blocks with “IN” and “OUT” markings. Please do NOT mis-connect input and
output connectors.
WARNING!
AII wiring must be performed by a qualified personnel.
WARNING!
It’s very important for system safety and efficient operation to use appropriate cable for AC input
connection. To reduce risk of injury, please use the proper recommended cable size as below.
Suggested cable requirement for AC wires.
Model Gauge Torque value
PDA1500-STATION 14AWG 0.5~0.6 Nm
PDA3000-STATION 12AWG 1.2~1.6Nm
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. Insert AC input wires according to polarities indicated on terminal block and tighten the terminal screws.
Be sure to connect PE protective conductor ( ) first.

L LINE (brown or black}
N Neutral (blue}
Warning: Shock
Be sure that AC power source is disconnected before
attempting to hardwire it to the unit.
4. Then, insert AC output wires according to polarities indicated on
terminal block and tighten terminal screws.
Be sure to connect PE protective conductor ( ) first.

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. 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
internal damage to the air conditioner.
