3. Safety Instructions
Adherence to these safety guidelines is crucial for preventing personal injury and damage to the inverter or connected devices.
- Ventilation: Ensure adequate ventilation around the inverter. Do not block cooling vents.
- Environment: Operate the inverter in a dry, cool, and well-ventilated area, away from direct sunlight, heat sources, flammable materials, and moisture.
- Connections: Always connect the inverter to a 12V DC battery system. Incorrect voltage input can cause damage. Ensure all connections are tight and correct polarity is observed (red to positive, black to negative).
- Grounding: Properly ground the inverter to prevent electrical shock.
- Load Capacity: Do not exceed the inverter's continuous power rating (2000W) or peak power rating (6000W). Overloading can damage the inverter and connected appliances.
- Maintenance: Do not attempt to open or modify the inverter. Refer all servicing to qualified personnel.
- Children: Keep the inverter out of reach of children.
- Emergency: In case of smoke, strange odors, or unusual noise, immediately disconnect the inverter from the battery and AC loads.

4. Setup
Follow these steps to set up your JIGUUN Pure Sine Wave Inverter.
4.1 Connecting the Inverter to a Battery
- Ensure the inverter's power switch is in the OFF position.
- Connect the red battery cable to the positive (+) terminal of your 12V DC battery and the positive (+) terminal on the inverter.
- Connect the black battery cable to the negative (-) terminal of your 12V DC battery and the negative (-) terminal on the inverter.
- Ensure all connections are secure and tight to prevent loose connections, which can cause overheating.
4.2 Grounding the Inverter
For safety, the inverter must be properly grounded. Connect a grounding wire (not supplied) from the inverter's grounding terminal to a suitable ground point, such as the chassis of a vehicle or a dedicated earth ground.
4.3 Detachable LCD Remote Control Setup
The inverter features a detachable LCD screen that can function as a wired remote control.
- To use the screen as a remote, gently detach it from the inverter unit.
- Connect the provided 5-meter network cable to the remote control port on the inverter and the corresponding port on the detached LCD screen.
- You can now monitor and control the inverter from a distance.

5. Operating Instructions
Once the inverter is properly installed and connected, follow these steps for operation.
5.1 Powering On/Off
- Ensure all AC loads are disconnected or turned off before powering on the inverter.
- Press the ON/OFF switch on the inverter (or the remote control) to turn it on. The LCD screen will illuminate.
- Connect your AC appliances to the inverter's outlets.
- To power off, first turn off all connected AC appliances, then press the ON/OFF switch on the inverter.
5.2 Understanding the LCD Display
The LCD display provides real-time operational data:
- Input Voltage (DC IN): Displays the current battery voltage.
- Output Voltage (AC OUT): Shows the AC output voltage (220V-240V).
- Frequency: Indicates the output frequency (50Hz).
- Load Power: Displays the current power consumption of connected devices in Watts.
- Battery Power: Visual indicator of battery charge level.
- Error Codes: Displays specific codes if a fault occurs (refer to Troubleshooting section).
Figure 5.1: An explanation of the LCD display elements, including input/output voltage, frequency, battery level, load power, and a table of common error codes (E1-E5).
