Injector Installation Manual

Phihong’s Power-over-Ethernet (PoE) Injector, available in models ranging from 15.4W to 90W (POE), ensures seamless power delivery for various applications. The Injector Installation Manual provides comprehensive guidelines to guarantee a safe and efficient setup.

Installation Steps:

  1. Pre-Installation Checks: Before connecting the Ethernet cable to the injector and equipment, unplug the injector from AC power. Verify that the output voltage and current align with the equipment’s requirements.
  2. Linkage and Cable Connection: Keep the linkage between the injector and its power cord tight. Connect the Ethernet cable to the equipment securely.
  3. Mechanical Stress Protection: Safeguard the power cord and input line against mechanical stress to prevent potential damage during use.
  4. Ventilation and Clearance: Ensure proper ventilation to prevent overheating. Maintain a 10-15cm clearance from other heat sources to guarantee optimal performance.
  5. Power Cord Requirements: Use an approved power cord greater than or equal to SVT/SPT or H03VV-F to maintain electrical safety.
  6. Long-Term Storage Precaution: If the end equipment won’t be used for an extended period, disconnect it from the injector to prevent damage from voltage peaks or lightning strikes.
  7. Additional Information: For detailed product information, users can refer to


  • Electrical Hazards: There’s a risk of electrical shock and energy hazards. In case of failures, consult a qualified technician instead of attempting self-fixing by removing the adapter case.
  • Fire and Electrical Shock Risks: Protect openings from foreign objects or liquids to avoid fire or electrical shock. Place or mount injectors on a reliable surface to prevent damage from drops or falls.
  • Environmental Considerations: Avoid placing injectors in damp environments or near water sources. Keep them away from high ambient temperatures or heat sources.
  • Compliance with Rated Values: Ensure that the output current and wattage do not exceed the rated values specified in the datasheets.
  • Safety during Cleaning: Disconnect the unit from AC power before cleaning. Use a slightly damp cloth for wiping, avoiding liquid detergents or aerosol cleaners.
  • Proper Disposal: When disposing of the product, contact a local qualified recycler to adhere to environmental guidelines.
  • FCC Compliance: The device complies with Part 15 of the FCC Rules, ensuring minimal interference. It must accept any received interference without compromising operation.
