3. Insert AC input and output cables according to polarities indicated on terminal
block and tighten the terminal screws. Be sure to connect PE protective conductor
first ( ).
AC input:
AC output:
4. Make sure the wires are securely connected.
WARNING: Be sure to that AC power source is disconnected before attempting to
hardwire it to the unit.
CAUTION: Be sure to connect AC wires with correct polarity. If L and N wires are
connected reversely, it may cause mains short-circuited when these inverters are
running in parallel.
CAUTION: Appliances such as air conditioner are required at least 2~3 minutes to
restart because it is 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 is 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.
