5.2 Connexions elèctriques

All electrical connections should be performed by a qualified technician in accordance with local and national electrical codes.

1. Connexió d'entrada de CA: Connect the 110V AC input cord from the converter to a dedicated 110V AC outlet or circuit in your RV. Ensure the circuit is properly fused or circuit-breaker protected.
2. DC Output Connection: Connect the DC output terminals of the converter to your RV's 12V DC distribution panel and battery bank.
   • Connect the positive (+) terminal (red) of the converter to the positive (+) terminal of your battery bank/DC distribution.
   • Connect the negative (-) terminal (black) of the converter to the negative (-) terminal of your battery bank/DC distribution.
   • Assegureu-vos que totes les connexions estiguin estretes i segures.
3. Posada a terra: Ensure the converter is properly grounded to the RV chassis.

5.3 Battery Type and Output Voltage Selecció

The PM3-55LK features adjustable output settings for different battery types and charging needs. Refer to the labels near the adjustment points on the unit.

• 3 Stage / Fixed Output: A switch or jumper may be present to select between 3-stage smart charging mode and a fixed output power supply mode. Consult your battery manufacturer's recommendations for the appropriate charging profile.
• Voltage Ajust: The unit allows for output voltage adjustment, typically between 13V and 16.5V. Use a small screwdriver to carefully adjust the potentiometer to the desired voltage setting for your battery type (e.g., 13V for standard lead-acid float, 16.5V for specific lithium charging profiles).

6. Instruccions de funcionament

6.1 Encès

Once all connections are secure and verified, connect the AC input cord to a live 110V AC power source. The converter will automatically begin supplying 12V DC power and charging the connected battery bank according to its selected charging profile.

6.2 Llum indicador LED

The unit features an LED indicator light to show its operational status. Refer to the unit's label or specific documentation for detailed interpretations of light patterns (e.g., solid green for normal operation, flashing for fault conditions).

6.3 4-Stage Càrrega intel·ligent

When in 3-stage (or 4-stage, depending on model specifics) smart charging mode, the converter intelligently manages the charging process to optimize battery life. This typically includes:

• Granel Stage: Delivers maximum current to rapidly charge the battery to approximately 80% capacity.
• Absorció Stage: Charges at a constant voltage, gradually reducing current as the battery approaches full charge.
• Flotador Stage: Maintains a lower, constant voltage to keep the battery fully charged without overcharging.
• (Per a alguns models) Igualació Stage: Aplica periòdicament un volum més alttage to balance cell voltages in certain battery types.

7. Manteniment

7.1 Neteja

Periodically inspect the converter for dust and debris. Ensure the cooling fan and vents are clear of obstructions. Use a soft, dry cloth to clean the exterior. Do not use liquid cleaners or solvents.

7.2 Canvi de fusibles

The unit is equipped with fuses (e.g., 40 Amp 12 Volt) for protection. If a fuse blows, disconnect all power to the converter, identify the blown fuse, and replace it with a fuse of the exact same type and rating. Using an incorrect fuse can cause damage or fire.

7.3 Comprovacions de connexió

Regularly check all electrical connections (AC input, DC output, grounding) to ensure they remain tight and free from corrosion.
