5. Product Interface and Indicators

The PoE injector features clearly labeled ports and LED indicators for easy setup and monitoring.

• PoE+ OUT Port: Connects to the PoE-powered device (PD) such as an IP camera or wireless access point. This port delivers both data and power.
• Ethernet Port: Connects to your network switch, router, or NVR for data input.
• PWR LED: Indicates power status. Green when power is supplied.
• PoE LED: Indicates PoE status. Green when PoE power is being delivered to a connected device.
• V+/V- Terminal: Power input terminal for 12-48VDC power supply.

6. Setup and Installation

Follow these steps to install and set up your Hereta PoE+ Injector:

1. Mounting:
   • DIN-Rail Mount: The injector comes with a pre-installed DIN-Rail bracket. Simply clip the device onto a standard DIN rail.
   • Wall Mount: If wall mounting is preferred, remove the DIN-Rail bracket and use the included wall mount bracket to secure the device to a flat surface using appropriate screws (not included).

2. Power Connection: Connect a 12-48VDC power supply (not included) to the V+/V- terminal block. Ensure correct polarity. The PWR LED will illuminate green once power is supplied.
3. Data Input Connection: Connect an Ethernet cable from your network switch, router, or NVR to the "Ethernet" port on the injector.
4. PoE Output Connection: Connect an Ethernet cable from the "PoE+ OUT" port on the injector to your IEEE 802.3af/at compliant PoE-powered device (PD). The PoE LED will illuminate green when power is successfully delivered to the PD.

7. Operating Instructions

Once properly installed and connected, the Hereta PoE+ Injector operates automatically. It detects the presence of an IEEE 802.3af/at compliant device and supplies the necessary power.

• Power On: Ensure the 12-48VDC power supply is connected and active. The PWR LED should be green.
• Device Connection: Connect your PoE-powered device to the PoE+ OUT port. The injector will negotiate power with the device.
• PoE Active: When a compatible PoE device is detected and powered, the PoE LED will turn green. If the LED is off, check the device connection and ensure it is PoE compliant.
• Data Transmission: Data will pass through the injector between your network and the connected PoE device.

8. Applications

The Hereta Hardened Industrial Gigabit PoE+ Injector is ideal for various applications requiring reliable power and data transmission in challenging environments:

• CCTV Security Transmission: Powering IP cameras in surveillance systems.
• Wireless AP Deployment: Providing power to wireless access points in remote or outdoor locations.
• IP Fixed Phones: Supplying power to VoIP phones in offices or industrial settings.
• Industrial Automation: Connecting and powering various network-enabled industrial sensors and devices.
