4. సంస్థాపన మరియు వైరింగ్

Proper installation and wiring are crucial for the safe and efficient operation of the MD1250N05 charger. Refer to the wiring diagram below for connections. Always ensure power sources are disconnected before making any connections.

Figure 3: Electrical Wiring Diagram

4.1 వైరింగ్ కనెక్షన్లు

1. Solar Panel Connection (PV): Connect your solar panel array to the terminals labeled 'PV'. Ensure correct polarity (+/-) and that the input voltage and current are within the specified limits (Max PV Input Voltage 55V DC, Max PV Input Current 45A). Fuses should be installed on the positive lines.
2. Start Battery Connection (AL): Connect the start battery (e.g., vehicle's starter battery) to the terminals labeled 'AL'. This allows the charger to manage the starter battery.
3. Electric Generator Connection (AL): Connect the electric generator to the same 'AL' terminals as the start battery. The charger will automatically recognize the generator type via its ignition signal.
4. Backup Battery Connection (BA): Connect your main backup battery (e.g., house battery in an RV) to the terminals labeled 'BA'. Ensure correct polarity. Fuses should be installed on the positive lines.

Important Safety Note: Always install appropriate fuses on the positive lines of all battery and solar panel connections as indicated in the wiring diagram to protect against overcurrent.
