2. Safety Instructions
Read all safety warnings and instructions carefully before installing and operating the device. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- High Voltage Warning: Electric fence energizers produce high voltage. Avoid contact with the fence line.
- Children and Animals: Keep children and untrained animals away from the electric fence.
- Installation: Install the energizer in a dry, sheltered location, away from flammable materials. Ensure proper grounding.
- Power Source: Only use the specified 230 V mains adapter or a 12 V deep cycle battery. Do not use damaged cables or adapters.
- Maintenance: Disconnect the energizer from the power source before performing any maintenance or repairs.
- Local Regulations: Adhere to all local regulations and standards for electric fence installation and operation.

4. Setup
4.1 Mounting the Device
- Choose a dry, sheltered location for the energizer, protected from direct sunlight and heavy rain.
- Mount the device securely to a wall or post using appropriate fasteners. Ensure it is easily accessible for monitoring and maintenance.
4.2 Grounding the Energizer
- Drive at least one galvanized ground rod (not included) into the earth, preferably in a moist area, at least 1 meter (3 feet) deep. For optimal performance, especially with longer fences or dry soil, multiple ground rods may be required.
- Connect the green ground connection cable from the energizer's ground terminal (marked with a ground symbol) to the ground rod. Ensure a secure, corrosion-free connection.
4.3 Connecting to the Fence
- Connect the red fence connection cable from the energizer's fence terminal (marked with a lightning bolt symbol) to your electric fence line.
- Ensure all fence insulators are intact and the fence line is free from vegetation contact to prevent power loss.
4.4 Power Connection
The AKO Duo Power Xi 8000 can be powered by either 230 V mains or a 12 V battery.
4.4.1 230 V Mains Operation
- Plug the 230 V mains power adapter into the designated input on the energizer.
- Plug the adapter into a standard 230 V AC wall outlet.
4.4.2 12 V Battery Operation
- Connect the red battery connection cable to the positive (+) terminal of a 12 V deep cycle battery.
- Connect the black battery connection cable to the negative (-) terminal of the 12 V deep cycle battery.
- Plug the other end of the battery connection cables into the designated 12 V input on the energizer.
- Ensure the battery is fully charged for optimal performance.
Note: Do not connect both 230 V mains and 12 V battery simultaneously. The device will automatically prioritize the 230 V mains if both are connected, but it is recommended to use only one power source at a time.

5. Operating the Device
5.1 Powering On
Once connected to a power source (either 230 V mains or 12 V battery) and properly grounded, the energizer will automatically power on. There is no separate on/off switch.
5.2 Monitoring Performance with LED Bargraph Display
The AKO Duo Power Xi 8000 features a multi-color LED bargraph display that provides real-time information on the output voltage and battery status. This allows for clear control and helps monitor the performance of your fence system at any time.
- Output Voltage: The LED segments indicate the current voltage on the fence line. A higher number of lit segments signifies stronger fence performance.
- Battery Status: If operating on 12 V battery, the display will also show the battery's charge level, allowing you to anticipate when recharging is needed.
5.3 Energy-Saving Circuit
The integrated energy-saving circuit automatically optimizes energy consumption based on fence conditions, extending battery life during 12 V operation and reducing power usage during 230 V operation.

6. Maintenance
Regular maintenance ensures the longevity and reliable performance of your AKO Duo Power Xi 8000.
- Visual Inspection: Periodically check the energizer, cables, and fence line for any visible damage, corrosion, or loose connections.
- Fence Line Clearing: Keep the fence line clear of vegetation, as contact with grass or weeds can significantly reduce fence voltage.
- Grounding System: Ensure the ground rods remain firmly in the earth and connections are secure and free of rust.
- Battery Maintenance (12 V operation): If using a 12 V battery, regularly check its charge level using the energizer's display or a separate battery tester. Recharge or replace the battery as needed.
- Cleaning: Gently wipe the energizer's casing with a damp cloth to remove dirt and dust. Do not use harsh chemicals or immerse the device in water.

7. Troubleshooting
If you encounter issues with your AKO Duo Power Xi 8000, refer to the following troubleshooting guide:
| Problem | Possible Cause | Solution |
|---|---|---|
| No power/LED display off | No power supply; faulty connection; discharged battery (12V) | Check mains adapter/outlet; check battery connections; recharge/replace battery. |
| Low fence voltage (few LED segments lit) | Poor grounding; fence shorting (vegetation, broken insulators); long fence line; discharged battery | Improve grounding (add rods); clear vegetation; inspect/replace insulators; check battery. |
| Intermittent pulses | Loose connections; internal fault | Check all cable connections; if problem persists, contact AKO support. |
| Device is hot | Overload; poor ventilation | Ensure proper ventilation; check for severe fence shorts. Disconnect if overheating persists. |
If you are unable to resolve the issue using this guide, please contact AKO customer support for further assistance.
