WARNING:
Be sure that AC power source is disconnected before attempting to hardwire it to the unit.
5.
Then, insert AC output wires according to polarities indicated on terminal block and tighten terminal screws.
Be sure to connect PE protective conductor (
)
first.

PV Connection
CAUTION:
Before connecting to PV modules, please install
separately
DC circuit breakers between inverter
and PV modules.
NOTE1:
Please use 600VDC/30A circuit breaker.
NOTE2:
The overvoltage category of the PV input is II.
Please follow the steps below to implement PV module connection:
CAUTION:
Appliances such as air conditioner requires 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 will be trigger overload fault and cut off output to protect your appliance but sometimes it still
causes internal damage to the air conditioner.
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.
