Follow these steps for proper installation of the circuit breaker.

4.1 ການຕິດຕັ້ງ

1. Ensure the power supply to the PV system is completely disconnected and secured against accidental re-energization.
2. Locate a suitable position on a standard 35mm DIN rail within an appropriate enclosure.
3. Hook the top edge of the circuit breaker onto the DIN rail.
4. Press the bottom of the circuit breaker firmly until it clicks into place on the DIN rail.

4.2 ການເຊື່ອມຕໍ່ສາຍໄຟ

1. Identify the input (source) and output (load) terminals. The circuit breaker typically has markings for input and output, and positive (+) and negative (-) terminals.
2. Strip the insulation from the DC cables to the appropriate length, ensuring no stray strands.
3. Insert the positive (+) DC cable from the PV array or charge controller into the positive input terminal.
4. Insert the negative (-) DC cable from the PV array or charge controller into the negative input terminal.
5. Connect the positive (+) DC cable to the load (e.g., inverter) from the positive output terminal.
6. Connect the negative (-) DC cable to the load from the negative output terminal.
7. Tighten all terminal screws securely. Refer to the product specifications for recommended torque values if available. Over-tightening or under-tightening can cause damage or poor connections.
8. Double-check all connections for correct polarity and tightness before restoring power.

5.1 ເປີດ/ປິດ

• ເພື່ອເປີດ: Push the operating handle upwards to the 'ON' position. The indicator window should display red.
• ເພື່ອປິດ: Push the operating handle downwards to the 'OFF' position. The indicator window should display green.

5.2 Understanding Indicator Windows

ຮູບທີ 5: Indicator windows showing ON (Red) and OFF (Green) states. This image clearly illustrates the visual cues for the circuit breaker's operational status, with a red indicator for 'ON' and a green indicator for 'OFF' or 'closed'.

• ຕົວຊີ້ວັດສີແດງ: The circuit breaker is in the 'ON' position, and current is flowing through the circuit.
• ຕົວຊີ້ວັດສີຂຽວ: The circuit breaker is in the 'OFF' position, and the circuit is open (no current flow).

5.3 Resetting After a Trip

If an overload or short circuit occurs, the circuit breaker will automatically trip, moving the handle to an intermediate or 'OFF' position. The indicator window will show green.

1. Identify and resolve the cause of the trip (e.g., remove overload, fix short circuit).
2. Before resetting, ensure the circuit is safe and the fault has been cleared.
3. Push the operating handle fully downwards to the 'OFF' position first, then push it upwards to the 'ON' position to reset the breaker.
4. If the breaker trips immediately again, do not force it. Re-evaluate the circuit for persistent faults.
