2. Important Safety Instructions
As an AC power supply equipment, the inverter’s output voltage is
with the same level as that of household power plug. Mind the AC
output terminals, or you may get an electric shock and result in life
danger!
Attentions:
Connect the DC input according to the requirement strictly. The
power inverter has a relatively wide input range, but too high or
too low input may cause problems even destroy the inverter.
A reverse polarity connection will blow the fuses in the inverter
and may damage the unit.
Do not expose the inverter to humid, flammable, explosive or
dust environment.
Keep the inverter out of children touch.
Inverter input is recommended to connect to battery, the min.
capacity of battery(expressed inAH) should be calculated in the
following way: 5times of the rated power of the inverter/battery
voltage. If for testing purpose, user should select DC power
supply current at least twice greater than that of the inverter
rated input to keep inverter normal operation. Use DC power
supply for testing may cause the damage of the inverter.
When the inverter works continuously, its surface may become
very hot, please make sure the air ventilation clearance around
the inverter is more than 10cm. Keep away from the material or
device which may suffer from high temperature when the
inverter is working. Do not install the inverter in airproof location
and keep enough space around the inverter.
The protective grounding must be connected to the ground. The
cross section of wire should not be less than 4mm2.

3
The wire connects between battery and inverter should be
shorter than 3m, the current density should be less than
3.5A/mm2while the output of inverter is fully loaded. If the wire
longer than 3m, the current density should be reduced.
A fuse or breaker should be used between battery and inverter,
the value of fuse or breaker should be twice of the inverter rated
input current.
Do not connect the battery charger or similar devices to the
input terminal of the inverter.
Do not put the inverter close to the flooded lead-acid battery
because the sparkle in the terminals may ignite the hydrogen
released by the battery.
It’s an off-grid inverter, do not connect the AC output terminals
to the grid or electrical source, otherwise the inverter may be
damaged.
This inverter can only be used singly, parallel connection or in
series will damage the inverters.
Risk of electric shock, don’t touch output port when the inverter
is working. The output is forbidden to connect other power
sources or grid, otherwise the inverter will be damaged. The
inverter must be in off, when connecting load.
Do not attempt to repair the fault inverter by yourself, otherwise it
may lead to a serious accident. Please contact the manufacture’
s engineer.

Operation Steps:
Step 1: Turn off the switch of inverter
Step 2: Connect the battery (‘+’ terminal with red line, ‘-’with black
line). Do not connect them by contraries, or the power inverter will
be damaged.
Step 3: Connect the protective grounding to the ground
Step 4: Connect the AC load to the AC outlet
Step 5: Switch on the fuse or breaker. Switch the inverter to ON
and then turn on the loads one by one. Check the operation state of
both power inverter and loads. ‘Green’ of the Working indicator
means the state is normal.
Step 6: If there are different loads, it is suggested that turn on the
load with large startup current first, such as television, then turn on
the load such as lamp when the inverter works stably.
Step 7: If the Fault indicator is ‘Red’ and the buzzer alarms or no
output when you turn on devices, switch off the loads and
power inverter immediately. Check the system by referring to the
troubleshooting guide. Turn on the devices again according to the
operation methods after the failure is removed.

(5) Mode Switch
When the switch No.1 is on the ON side, output frequency is 60Hz, otherwise
is 50Hz.
When the switch No.2 is on the ON side, the output voltage is 230VAC,
otherwise is 220VAC.
NOTE: Both the output frequency and the output voltage
change availability after restart the inverter.
WARNING: DO NOT turn ON/OFF the mode switch when the
inverter is working.
