Wichtige Überlegungen:
- Ensure appropriate fuses/breakers are installed on all positive lines as indicated in the diagram.
- The ACC ignition wire is recommended for vehicles with smart alternators to ensure proper charging initiation.
- Maintain proper cable gauge for the current draw to prevent voltage Tropfen und Überhitzung.
6. Bedienungsanleitung
6.1. Auswahl des Batterietyps
Drücken Sie die "WÄHLEN" button on the charger to cycle through and choose the appropriate battery type for your auxiliary battery (AGM, Gel, Calcium, Lead Acid, or LiFePO4). The selected battery type will be indicated by an illuminated LED.
6.2. Rückladefunktion
To activate reverse charging and revive a flat start battery from your auxiliary battery, press the "REVERSE CHARGE" button. This feature ensures your starter battery remains charged for off-road use.

6.3. DC Charging Priority
The charger is configured with DC charging priority. When both the vehicle's start battery (DC input) and solar panels are connected and meet the startup conditions, the charger will prioritize the vehicle battery input. If solar charging is already active, the system will continuously monitor the DC input and automatically switch to DC power if conditions are met.
- Startup Conditions:
- DC-Eingang: 13-24V
- Solar Input: 13-26V

7. Wartung
Regelmäßige Wartung gewährleistet die Langlebigkeit und optimale Leistung Ihres Ladegeräts:
- Überprüfen Sie regelmäßig alle Kabel und Verbindungen auf Anzeichen von Verschleiß, Korrosion oder Lockerung.
- Halten Sie das Ladegerät sauber und frei von Staub und Schmutz. Verwenden Sie zum Reinigen ein trockenes Tuch.
- Sorgen Sie für ausreichende Belüftung rund um das Gerät, um eine Wärmeentwicklung zu vermeiden.
- Check the condition of fuses/breakers regularly and replace if necessary with the correct rating.
8. Fehlerbehebung
Sollten Sie Probleme mit Ihrem Ladegerät haben, beachten Sie bitte die folgenden gängigen Schritte zur Fehlerbehebung:
- Ladegerät wird nicht aktiviert:
- Verify that both DC input (from start battery) and/or solar input meet the minimum voltage requirements (DC: 13-24V, Solar: 13-26V).
- Prüfen Sie alle Verbindungen auf korrekten Sitz und Polarität.
- Inspect fuses/breakers for continuity.
- Ensure the ACC ignition wire (if used) is receiving power when the vehicle is running.
- Geringe Ladeleistung:
- Confirm the correct battery type is selected on the charger.
- Überprüfen Sie, ob zu viel Lautstärke vorhanden ist.tage drop in wiring due to undersized cables or long runs.
- Ensure solar panels are clean and receiving adequate sunlight if solar charging is active.
- Verify the alternator is functioning correctly and providing sufficient voltage.
- Überhitzung:
- Ensure the charger is installed in a location with sufficient airflow.
- Remove any obstructions around the cooling fins.
- Reduce load if possible, or ensure the charger is not operating beyond its rated capacity.
If the issue persists after performing these checks, contact ATEM POWER customer support.
