2. Safety Information
Please read all safety instructions carefully before installing and operating the inverter. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Installation: Ensure the inverter is installed in a well-ventilated area, away from flammable materials, moisture, and direct sunlight.
- Grounding: Always connect the inverter to a proper earth ground to prevent electrical hazards.
- Battery Connection: Connect the inverter directly to a 12V battery. Ensure correct polarity (red to positive, black to negative). Incorrect connections can damage the inverter and battery.
- Load Capacity: Do not exceed the inverter's rated output of 1000W. The surge power is 2000W, but continuous operation above 1000W can cause damage.
- Ventilation: Do not block the cooling fans or ventilation openings. Adequate airflow is crucial for preventing overheating.
- Maintenance: Only qualified personnel should perform maintenance or repairs. Do not attempt to disassemble the inverter.
- Emergency: In case of smoke, unusual odors, or abnormal operation, immediately disconnect the power source.

5. Setup
Follow these steps for proper installation of your inverter.
5.1. Mounting the Inverter
Choose a dry, well-ventilated location for mounting the inverter. Use the provided mounting screws and plastic anchors to secure the inverter firmly to a stable surface. Ensure there is sufficient space around the unit for airflow, especially around the cooling fans.
5.2. Connecting to the Battery
- Ensure the inverter's ON/OFF switch is in the 'OFF' position.
- Connect the red battery cable to the inverter's positive (+) terminal and then to the battery's positive (+) terminal.
- Connect the black battery cable to the inverter's negative (-) terminal and then to the battery's negative (-) terminal.
- Ensure all connections are tight and secure. Loose connections can cause overheating and damage.
5.3. Grounding the Inverter
Connect the provided earth terminal cable to the inverter's earth terminal and then to a reliable ground point (e.g., vehicle chassis, earth rod). This is crucial for safety.
5.4. Connecting the Remote Control
Plug the remote control cable into the remote control port on the inverter. Mount the remote control unit in a convenient location using the provided screws and anchors. The 450cm cable allows for flexible placement, enabling remote monitoring and control of the inverter's status.
