3. Safety Information
Always observe the following safety precautions when installing or operating the ATEM POWER DC to DC Battery Charger:
- Ensure all connections are secure and correct before powering on the unit.
- Do not expose the charger to excessive moisture or extreme temperatures beyond its operating range.
- Only connect to compatible battery types as specified in this manual.
- Avoid short-circuiting the terminals.
- Installation should be performed by a qualified professional if you are unsure about the wiring process.
- Keep out of reach of children.
4. Setup and Installation
Proper installation is crucial for the performance and longevity of your charger. Follow these steps carefully:
4.1. Mounting the Charger
Select a secure, well-ventilated location for mounting the charger. Ensure it is protected from direct water exposure and excessive heat. The charger is designed for in-vehicle or under-bonnet installation.
4.2. Wiring Diagram
Refer to the diagram below for correct wiring connections. It is recommended to use appropriate fuses or circuit breakers for both the input and output lines.

Two diagrams are presented: one illustrating the dual input power capability, allowing simultaneous charging from solar and DC sources with DC priority, and another showing a typical 4WD installation setup for the charger with traditional or smart alternators.

4.3. Anderson Plug Connections
The charger is equipped with Anderson style plugs for ease of connection. Ensure correct polarity and secure fit for each plug.
| Pin No. | Color | Function |
|---|---|---|
| 1 | Blue | Solar Input (+) |
| 2 | Black | GND (Ground) |
| 3 | Yellow | Output (+) |
| 4 | Black | GND (Ground) |
| 5 | Red | DC Input (+) |
| 6 | Black | GND (Ground) |
| 7 | Blue (thin) | ACC Ignition Line (Optional) |

5. Operating Instructions
Once installed, the charger operates largely automatically. However, you can select the battery type for optimized charging.
5.1. Battery Type Selection
The charger supports various battery chemistries. To select the appropriate charging profile:
- Press the 'SELECT' button on the charger's control panel.
- Cycle through the available battery types (Lead Acid, AGM/GEL, Calcium, LiFePO4) until the desired type is indicated.
- The charger will automatically adjust its charging algorithm for the selected battery type.
5.2. Charging Priority
The charger is designed with DC charging priority. If both solar and DC inputs are available and meet the starting conditions, the vehicle battery input will be prioritized. The system continuously monitors inputs and will switch to DC power if conditions are met, even if solar charging is in progress.

This image focuses on the charger's control panel, demonstrating its ability to prolong battery life through an advanced four-stage charging process and offering flexible fast and slow charging options to suit energy needs.
6. Maintenance
The ATEM POWER DC to DC Battery Charger requires minimal maintenance. Follow these guidelines to ensure optimal performance:
- Regularly inspect all wiring and connections for signs of wear, corrosion, or looseness.
- Keep the charger clean and free from dust and debris. Use a dry cloth for cleaning.
- Ensure the ventilation fins are not obstructed to allow for proper heat dissipation.
- Periodically check the battery terminals for corrosion and clean them if necessary.
7. Troubleshooting
If you encounter issues with your charger, refer to the table below for common problems and their solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Charger not turning on | No input power; Loose connections; Blown fuse/breaker | Check vehicle battery and solar panel connections; Ensure all plugs are secure; Inspect and replace fuses/breakers if necessary. |
