4. Ўстаноўка
Before beginning installation, ensure the main power supply to the distribution board is switched OFF and locked out to prevent accidental re-energization.
4.1 Мантаж
- Locate an available space on the DIN rail within your electrical distribution board.
- Position the circuit breaker onto the DIN rail. The device is designed for easy clip-on mounting.
- Press firmly until the circuit breaker clicks securely into place on the DIN rail.
4.2 Электраправодка
The Legrand 407704 features top input and bottom output screw terminals for U+N connections.
- Connect the incoming phase (U) and neutral (N) wires to the top terminals of the circuit breaker. Ensure proper polarity.
- Connect the outgoing phase (U) and neutral (N) wires to the bottom terminals of the circuit breaker, leading to the circuit it protects.
- Tighten all screw terminals securely to the recommended torque to ensure good electrical contact and prevent overheating. Refer to local electrical codes for specific torque values.
- If using HX³ optimized universal busbars, ensure they are correctly inserted and connected according to the busbar manufacturer's instructions.
After wiring, double-check all connections for tightness and correct polarity before restoring power.
5. Аперацыя
5.1 Уключэнне/выключэнне
- To switch the circuit breaker ON, push the toggle switch upwards to the 'I' (ON) position.
- To switch the circuit breaker OFF, push the toggle switch downwards to the 'O' (OFF) position.
5.2 Automatic Tripping
The circuit breaker will automatically trip to the 'O' (OFF) position in the event of an overload or short circuit. This action protects the electrical circuit and connected appliances from damage.
If the circuit breaker trips, investigate the cause of the fault before attempting to reset it. Common causes include too many appliances on one circuit or a faulty appliance.
5.3 Resetting the Circuit Breaker
- Identify and rectify the cause of the trip (e.g., unplug faulty appliances, reduce load).
- Push the toggle switch fully downwards to the 'O' (OFF) position first, then push it upwards to the 'I' (ON) position to reset.
- If the circuit breaker immediately trips again, do not attempt to reset it further. Consult a qualified electrician.
6. Тэхнічнае абслугоўванне
The Legrand DX³6000 circuit breaker is designed for maintenance-free operation under normal conditions. However, periodic checks are recommended:
- Візуальны агляд: Перыядычна правярайце аўтаматычны выключальнік на наяўнасць прыкмет фізічных пашкоджанняў, змены колеру або няшчыльных злучэнняў.
- Герметычнасць клем: Over time, screw terminals can loosen due to thermal cycling. It is advisable to have a qualified electrician periodically check and retighten all terminal screws to ensure optimal electrical contact.
- Уборка: If necessary, clean the exterior of the circuit breaker with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is OFF before cleaning.
Do not attempt to open or repair the circuit breaker. There are no user-serviceable parts inside.
7. Выпраўленне непаладак
