4. Uppsetning og uppsetning

MIKILVÆGT: Uppsetning verður að vera framkvæmd af löggiltum rafvirkja í samræmi við allar gildandi rafmagnsreglur og staðla.

1. Rafmagnstenging: Ensure all power to the electrical panel is turned OFF at the main disconnect and verified with a voltage tester. Lock out and tag out the main disconnect.
2. Aðgangur að spjaldi: Fjarlægðu hlífina af rafmagnstöflunni varlega.
3. Staðsetning rofa: Identify the appropriate slot in the panel for a three-pole breaker.
4. Tenging: Connect the load wires to the designated terminals on the circuit breaker. The BQ3B040 is a lug-out breaker, meaning wires connect directly to the lugs. Ensure all connections are tight and secure, adhering to torque specifications if provided on the breaker or panel.
5. Uppsetning: Snap the circuit breaker firmly into place on the bus bar. Ensure it is fully seated.
6. Samsetning spjaldsins: Skiptu um hlífina á rafmagnstöflunni.
7. Rafmagnsendurheimt: Endurræstu rafmagnið á aðalþjónustuborðinu.

5. Notkunarleiðbeiningar

The SIEMENS BQ3B040 circuit breaker operates as a protective device for your electrical circuit. It has three primary states:

• Kveikt: In this position, power is flowing through the circuit breaker to the connected load.
• SLÖKKT: In this position, power to the connected load is interrupted.
• TRIPPED: If an overload or short circuit occurs, the breaker will automatically move to a tripped position (often midway between ON and OFF, or fully OFF depending on the design). This indicates a fault in the circuit.

To reset a tripped breaker, first move the handle firmly to the OFF position, then push it to the ON position. If the breaker immediately trips again, do not attempt to reset it repeatedly. Investigate the cause of the fault.

6. Viðhald

Rofar þurfa almennt lágmarks viðhald. Hins vegar er mælt með reglulegu eftirliti:

• Sjónræn skoðun: Annually, or as local codes require, have a qualified electrician inspect the circuit breaker and its connections for any signs of overheating, loose wires, or physical damage.
• Þrif: Ensure the area around the circuit breaker is free from dust and debris. Do not use liquids for cleaning inside the electrical panel.
• Próf: Do not attempt to test the tripping mechanism yourself. This should only be done by qualified professionals using specialized equipment.

7. Bilanagreining

If you experience issues with your circuit breaker, consider the following:

• Brotferðir oft: This indicates an overload or a short circuit on the protected circuit. Disconnect some appliances or devices from the circuit, or inspect for damaged wiring. If the problem persists, consult a qualified electrician.
• Rofinn endurstillist ekki: If the breaker immediately trips after being reset, a persistent fault (overload or short circuit) is present. Do not force the breaker.
• Enginn straumur í rafrásina: Check if the breaker is in the OFF or TRIPPED position. If it is ON and there is still no power, check other breakers or consult an electrician.

Ef um langvarandi eða flókin rafmagnsvandamál er að ræða skal alltaf hafa samband við löggiltan rafvirkja.
