Preparation
Before connecting all wiring, pleaseUHPRYHWKHERttom cover by removing two screws as shown below.
Mounting the Unit
Consider the following points before selecting where to install:
z Do not mount the inverter on flammable
construction materials.
z Mount on a solid surface
z Install this inverter at eye level in order to allow
the LCD display to be read at all times.
z The ambient temperature should be between 0°C

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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 (+) LV connected to positive (+) and negative (-) LV 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 $& LQSXW over current. 5ecommended specLILFDWLRQ of AC breaker is 30A

PV Module Wire Connection:
Please follow below steps to implement PV module connection:
 Remove insulation sleeve 10 mm for positive and negative conductors.
 Check correct polarity of connection cable from PV modules and
PV input connectors. Then, connect positive pole (+) of connection cable
to positive pole (+) of PV input connector. Connect negative pole (-) of
connection cable to negative pole (-) of PV input connector.
3. Make sure the wires are securely connected.
Final Assembly
After connecting all wirings, please put bottom cover back by screwingLQWKH two screws as shown below.
