1.5 Operating Environment
To ensure the product's optimal performance, The operating environment should at
least satisfy the below requirements:
1.Place the product in a clean, dry, and well-ventilated area. (When installing the product in a
spacious cabin, make sure to provide ventilation.)
Maintain an appropriate ambient temperature. (The inverter can operate in an environment
ranging from -25°C to +55°C; operating in high temperatures is strictly prohibited.)
Maintain the relative humidity within the range of 5% to 95%, avoiding condensation.
2.Altitude ≤2500m. If the altitude exceeds 1000 meters, it's recommended to reduce the rated
capacity of the machine. (For altitudes above 3000 meters, the rated output current decreases
by 3% for every 100 meters of altitude increase.)Ensure there are no corrosive gases or other
corrosive substances nearby, and no flammable or explosive items.
3.Ensure the input power supply complies with safety regulations.

2 Installation and Operation
The installation of this product requires careful planning, including selecting the installation
location, properly configuring the load, choosing appropriate cables, and ensuring correct
connections to ensure safe and normal operation of the product.
2.1 Installation Preparation
1. Before using this product, carefully consider the power of the load equipment to avoid
overloading the inverter.
2. Under normal operating conditions, the actual power consumption of the load equipment,
especially in standby mode, may be lower than the specified power. Users should use the
nominal power of the equipment as the basis for calculations and consider the startup
current to ensure sufficient power margin for reliable inverter power supply.
2.2 Installation Location
1. Choose the installation location based on principles of heat dissipation, easy wiring, and
compliance with the requirements of the product's operating environment. Select a stable
installation location whenever possible.
2. Keep the air inlet and outlet unobstructed. Maintain at least 300mm of clearance around
the air inlet and outlet. Ensure there is enough operating and maintenance space based on
the installation conditions.
3. When installing vertically, pay attention to foreign objects falling into the air duct to avoid
blocking the product inlet and outlet
4. Ensure the product is securely installed to prevent shaking or falling.
5. Use M8x15 combination bolts to secure the product in place using the designated mounting
holes. The tightening torque of the bolts should be at least 18Nm.
Figure 2-1
English

10
The installation position should be far from water, steam, and other liquids. Keep away
from flammable and explosive materials.
Avoid installing or storing the inverter in environments with high corrosiveness, high
dust levels, high temperatures, high humidity, and especially environments with metal
substances that could fall into the enclosure.
Do not place any objects on top of the enclosure. Parallel operation is not supported.
2.3 Cable Connection, Startup, and Shutdown
Prior to connecting cables, disconnect the upstream power source.
• Ensure reliable grounding of the inverter. Use thicker ground cables if possible and connect
them close to the inverter. Keep the grounding cable short.
• Use cables that meet the requirements. Avoid using cables that are overloaded to prevent fire
or electric shock accidents. Even after cutting off the input power supply, there will still be high
voltage inside the inverter. Do not open the enclosure to touch internal components, as this
could cause harm to operators and the product.
2.3.1 Cable Connection
DC input cable and port definition:
• ①is the DC input socket of the inverter (meaning of ①detailed in 1.2 Parts and Diagram).
The connector of the DC cable is designed with an anti-reverse lock to match the inverter's DC
input port. Pay attention to the direction of the lock when connecting.
• Ensure the polarity of the DC cable input terminals is correct. After connecting the connectors,
tighten them securely.
• Make sure to disconnect the power source before connecting..

3.1 Protection
This product has comprehensive protection functions. In the event of faults listed in the table
below, the product will enter a protection state and shut off the output to ensure that the load is
not damaged, and the product itself is protected.

When the inverter is first started and the input voltage is exactly between the protection
and recovery points (80/85V, 120/115V), the machine will be in protection state. The
protection state will be canceled when the input voltage is between the undervoltage
recovery value and the overvoltage recovery value.
3.2 Indicator Light
The front panel of this product has 2 indicator lights. Since the inverter itself has comprehensive
protection functions, once abnormalities or faults occur, the inverter will shut off or stop output.
The indicator lights will respectively indicate the corresponding abnormal information and the
operating status of the inverter.

3.3 Common Fault Causes and Solutions
Before using this product, carefully consider the power of the load equipment to avoid
overloading the inverter. The actual power of the load equipment in general operating
conditions, especially in standby mode, is slightly lower than the labeled power. Users should
rely on the nominal power of the device when using it and consider the impact current when the
device starts. Provide sufficient power margin to ensure reliable power supply from the inverter.
Fault Cause Solution
All lights are off, the
inverter does not
start
Switch failure Check if the switch is working
properly or damaged
Input undervoltage Check if the input voltage is normal
Reverse connection Check if the DC input is reversed
Internal fault Contact your dealer for
maintenance
Red light flashes Output overload warning Remove some devices and check
the status of the red light
Green light steady
on, no output
Device does not start Check if the output lines L, N, GND
are connected correctly
No voltage at output port Contact your dealer for
maintenance
Green light off, red
light steady on
Overvoltage protection
Check if the input voltage is
normal; normal operation can be
restored when the input voltage is
within the recovery range
Overload protection Remove some devices and then
power on again
Overtemperature protection
Temporarily stop using the
inverter.
Resume operation after the
inverter temperature drops
Short-circuit protection After eliminating the line fault,
power on again

4 Maintenance
To ensure the continuous and proper operation of this product, regular maintenance and
inspection are required.
When conducting maintenance, adhere to the nominal power of the equipment and consider the
surge current during startup. Sufficient power margin should be retained to ensure the reliable
power supply of the inverter.
1. Regularly inspect whether the connection cables are aging and whether cable connection
points are securely fastened and safe.
2. Periodically open the enclosure to clean dust and any debris that might hinder ventilation
from the cooling fans. Also, check the normal operation of the fans. Refer to point 3 for
guidance on opening the enclosure.
3. Opening the enclosure for maintenance requires the expertise of a professional:
Before opening the enclosure for maintenance, the power supply should be completely
disconnected, and the system should be powered down for at least 10 minutes or longer. This
waiting time is necessary to allow the capacitors to discharge fully (there are high-capacity
capacitors inside the machine that require a certain amount of time for discharge). During
disassembly, take care not to damage components and parts, and pay attention to the order
of connecting wires. Specific maintenance requirements include:
- Clean dust and debris inside the enclosure.
- Check if the terminals and screws inside the enclosure are securely fastened.
- Inspect for any traces of overheating and damaged components left inside the enclosure.
- Check if the wires inside the enclosure have aged.
4. When reopening the enclosure of a previously maintained inverter, a trial run should be
conducted before putting it back into operation to ensure reliable power supply from the
inverter.
