WARNING: Shock Hazard
Installation must be performed with care due to high battery voltage in series.
CAUTION!!
Do not place anything between the flat part of the inverter terminal and the ring
terminal. Otherwise, overheating may occur.
CAUTION!!
Do not apply anti-oxidant substance on the terminals before terminals are connected
tightly.
CAUTION!!
Before making the final DC connection or closing DC breaker/disconnector, be sure
positive (+) must be connected to positive (+) and negative (-) must be connected to negative (-).
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.
CAUTION!! There are two terminal blocks with “IN” and “OUT” markings.
ENSURE that utility AC input is
connected to IN and load AC to OUT and not the wrong way round and also that Line and Neutrals are
connected correctly
.
WARNING! All 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.

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 (
) first.

WARNING:
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.
