The front panel features two 115V AC outlets, a 5VDC 2.1A USB charging port, an ON/OFF switch, and indicator lights for power and fault status. The top surface displays the brand 'Samlexpower 250' along with key specifications like 'DC-AC Inverter,' '250 Watts,' '12 VDC Input,' '115 VAC Output,' and 'Model SAM-250-12.'

Front Panel

• 115V AC Outlets (x2): Standard outlets for connecting AC-powered devices.
• 5VDC 2.1A USB Port: For charging USB-compatible electronic devices.
• ON/OFF Switch: Controls the power supply to the inverter.
• Power Indicator Light: Illuminates green when the inverter is powered on and operating normally.
• Fault Indicator Light: Illuminates red to indicate an error condition or when the inverter enters protection mode.

Rear Panel

• DC Input Terminals: Connections for the 12V DC power source (e.g., vehicle battery, cigarette lighter socket).
• Cooling Fan: Automatically activates to dissipate heat and maintain optimal operating temperature.

Setup

1. Choose a Location: Select a flat, stable surface for the inverter. Ensure the area is dry, well-ventilated, and free from direct sunlight, heat sources, and flammable materials. Allow at least 6 inches of clear space around the inverter for proper airflow.
2. Connect to 12V DC Power Source:
   • For Cigarette Lighter Socket (up to 150W): Insert the cigarette lighter plug firmly into your vehicle's 12V accessory socket. This method is suitable for lower power applications.
   • For Direct Battery Connection (full 250W): Connect the red battery clamp to the positive (+) terminal of your 12V battery and the black battery clamp to the negative (-) terminal. Ensure all connections are secure and tight to prevent voltage drop and overheating.
3. Verify Connections: Double-check all power connections to ensure they are correctly polarized and securely fastened. Loose connections can cause poor performance or damage.

Operating Instructions

1. Turn On the Inverter: After securing all connections, flip the ON/OFF switch on the front panel to the "ON" position. The green Power Indicator Light should illuminate, indicating the inverter is ready for use.
2. Connect AC Devices: Plug your AC-powered device(s) into the 115V AC outlets. Ensure the total combined wattage of all connected devices does not exceed 250 watts.
3. Connect USB Devices: Plug your USB-powered device(s) into the 5VDC 2.1A USB port for charging.
4. Monitor Operation: Observe the Power Indicator Light. If the red Fault Indicator Light illuminates, immediately disconnect all devices and refer to the Troubleshooting section.
5. Turn Off the Inverter: When you are finished using the inverter, turn off the inverter using the ON/OFF switch before disconnecting it from the 12V power source.

Important Considerations:

• The inverter is designed for 12V DC input only. Connecting to other voltages may damage the unit.
• Some devices with high startup current (e.g., motors, compressors, refrigerators) may exceed the inverter's surge capacity, even if their continuous wattage is within limits.
• For optimal performance and to prevent excessive battery drain, it is recommended to operate the inverter with the vehicle engine running when connected to a car battery.

Maintenance

• Keep the inverter clean and free from dust and debris. Use a dry cloth for cleaning.
• Ensure the cooling fan vents are unobstructed at all times to allow for proper airflow and heat dissipation.
• Store the inverter in a cool, dry place when not in use, away from extreme temperatures and moisture.
• Regularly check all electrical connections for tightness and signs of corrosion. Clean any corroded terminals.
