2. Installation
2.1 Warning
Please read the manual carefully to get familiar with the installation steps before
installation.
Be very careful when installing the batteries, especially flooded lead-acid battery.
Please wear eye protection, and have fresh water available to rinse if any contact
with battery acid.
Keep the battery away from any metal objects, which may cause a short circuit of
the battery.
Loose connections and corroded wires may result in high heat that can melt wire
insulation, burn surrounding materials, or even cause a fire. Ensure tight
connections and use cable clamps to secure cables and prevent them from
swaying in motion.
Select the system connection cables according to the current density no higher
than 5A/mm2.(In accordance with the National Electrical Code Article 690,
NFPA70).
For outdoor installation, keep out of the direct sunshine and rain infiltration.
High voltage still exists inside the inverter after turning off the switch, do not open
or touch the internal devices, wait five minutes before conducting related
operations.
Please do not install the inverter in humid, greasy, flammable, explosive, dust
accumulative or other severe environments.
Prohibit reverse connection at the battery input end; otherwise it will easily
damage the equipment or cause unpredictable danger.
Both utility input and AC output are of high voltage;please do not touch the wiring
connection.
When the fan is working, please do not touch it to avoid injury.

IMPORTANT: The wire size is for reference only, use thicker wires to lower the
voltage drop and improve the system performance when the distance between utility
and inverter or between inverter and batter is far.
IMPORTANT: The above wire size and circuit breaker size are for
recommendation only, please choose suitable wire and circuit breaker according to
the practical situation.
2.3Instructions
Installation steps：
Step1：Professional personnel read this manual carefully.
Step2：Determine the installation location and heat dissipation space.
Move the equipment: as the equipment is relatively large, it is recommended to use
forklift or crane; if the ground is flat, it can be moved by wheels.
Place to the location: As the equipment is heavy, it is recommended to be placed
on flat ground, with 300mm space reserved all around, to ensure heat dissipation.
Fix the equipment: If choose the optional caster, rotate counterclockwise to fix and
rotate clockwise to move.
WARNING: Risk of explosion!
Never install the inverter with flooded batteries in a sealed enclosure! Do not
install the device in a confined area where battery gas can accumulate.

13
Step3：Take down the junction box cover plate with special tools.
Step4：Wiring

14
Wiring order:
❶Ground——❷Battery——❸Utility——❹AC loads
WARNING: Never connect the utility to the inverter output; otherwise the
inverter may be damaged.
Grounding
The voltage of the whole system exceeds the safety voltage level. Thus reliable
grounding is needed. The grounding wire shall be the thicker wire(no less than
35mm2), and shall be as short as possible. The grounding point shall be as close as
possible to the inverter.
CAUTION: When wiring, follow the order ❶❷❸❹ to connect the cables
to the equipment, then follow the order ❶❷❸❹ to connect ground, battery,
utility and load.
WARNING: Make sure all the wiring connections are reliable, otherwise
massive heat would accumulate at the connection points to damage the
terminals, or even cause a fire.
WARNING: Danger, high voltage! Utility input, AC output and DC input
will produce high voltage, do not close the breakers during wiring, and make
sure the correct polarity of each component.
Step5：Connect the optional accessories

Method 1: Press the “AC output” button for 3 seconds, the inverter would start the
output.
Method 2: Connect the remote switch, short-circuit the cable 1(red) and cable
2(white) of the remote switch and RS485 communication interface, the inverter
would start the output.

Indicator：Inverter indicator slowly flashing and load indicator on solid.
LCD：
Step11：Turn on the load
LED indicators: Inverter and load indicators are slowly flashing.
CAUTION: In case the power is supplied to the different AC loads, it is
suggested to turn on the loads with larger surge current first, till the load
working well, then turn on the loads with smaller surge current. Especially for
inductive loads, should be turned on one by one. Do not turn on the loads at
the same time, so as not to cause excessive impact to the inverter, to shorten
its life span.
CAUTION: In case the inverter is not in regular operation, or LCD or
indicator displays abnormal, refer to Section 5 to clear the fault or contact the
after-sale service personnel of our company.
Step12：Power off the equipment
Open the AC load circuit breaker—long press “AC output” button to turn off the
inverter output—open the bypass circuit breaker—open the battery circuit breaker.
WARNING: As electricity exists in the capacitance, the LCD screen would
be off after 30 seconds; wait 5 minutes before opening the equipment to repair.
WARNING: After the inverter is disconnected from utility and
battery bank, need to wait 5 minutes before touching the internal conductive
devices.
WARNING: As the inverter has soft stat design and only takes effect
when the first time it starts, do not frequently switch the input circuit breaker
when the inverter is incompletely powered off, otherwise the input battery
would undergo high current impact. That is, the input circuit breaker can be
closed again after the LCD screen is off.

2.4Output voltage/frequency grade switch
Operating steps:
Open the cover plate on the inverter right side, find the dial switches on the control
board which is located on the top left corner, see above picture. Set the output
voltage/frequency according to demand, then restart the inverter to take effect.
IMPORTANT: The factory default output voltage is 220VAC, the output
frequency is 50Hz.
IMPORTANT: The accessories can refer to the Packing list.
When the dial switch 1 is placed to the ON side, the output
frequency is 60Hz, otherwise it is 50Hz,
When the dial switch 2 is placed to the ON side, the output
voltage is 230VAC, otherwise it is 220VAC.
