Instruccions importants de seguretat
ADVERTÈNCIA: Risc de descàrrega elèctrica. Desconnecteu l'alimentació abans de la instal·lació o el manteniment.
- La instal·lació l'ha de dur a terme un electricista qualificat d'acord amb les normes elèctriques nacionals i locals.
- Assegureu-vos el subministrament voltage matches the ballast's rated voltage (120 V).
- Do not install in locations where the ambient temperature exceeds the ballast's maximum operating temperature.
- Do not connect to a dimming circuit unless the ballast is specifically rated for dimming.
- Ground the ballast properly to prevent electrical hazards.
Configuració i instal·lació
Follow these steps for proper installation of the KTEB-2C72-1-TP ballast:
- Desconnexió d'alimentació: Before beginning any work, ensure that the main power supply to the fixture is turned off at the circuit breaker. Verify with a voltage provador.
- Old Ballast Removal: If replacing an existing ballast, carefully disconnect all wires from the old ballast. Note the wiring configuration or take a photograph for reference. Remove the old ballast from the fixture.
- Mounting the New Ballast: Secure the new KEYSTONE KTEB-2C72-1-TP ballast inside the fixture using appropriate screws or mounting hardware. Ensure it is firmly attached to prevent vibration.
- Connexions de cablejat: Refer to the wiring diagram provided on the ballast label.
- Connecteu el filferro negre from the ballast to the 120V AC Línia filferro (calent).
- Connecteu el fil blanc from the ballast to the 120V AC Neutre filferro.
- Connecteu el fil verd (or bare copper) from the ballast to the fixture's Terra filferro.
- Connect the ballast's lamp wires to the fluorescent lamp holders (sockets) as indicated by the wiring diagram. This ballast supports two F32T8 lamps. Ensure all connections are secure and insulated.
- Lamp Instal·lació: Insert the F32T8 fluorescent lamps into their respective lamp titulars.
- Restauració d'energia: Once all connections are secure and lamps are installed, restore power at the circuit breaker.
- Prova: Engegueu l'interruptor de la llum per comprovar el funcionament correcte.
Always consult the wiring diagram printed on the ballast itself for the most accurate and specific connection instructions.
Instruccions de funcionament
The KEYSTONE KTEB-2C72-1-TP electronic ballast operates automatically once properly installed and powered. It provides the necessary voltage and current to ignite and sustain two F32T8 fluorescent lamps.
- Encès/apagat: Feu servir l'interruptor de paret estàndard connectat a l'aparell per encendre la lamps encès o apagat.
- Inici instantani: This electronic ballast is designed for instant start operation, meaning lamps should illuminate immediately upon power application.
- Funcionament normal: Lamps should provide consistent, flicker-free illumination.
Manteniment
The KTEB-2C72-1-TP ballast is designed for long-term, maintenance-free operation. However, periodic checks of the lighting fixture are recommended.
- Neteja: Ensure the ballast and fixture are kept free of dust and debris to allow for proper heat dissipation. Disconnect power before cleaning.
- Lamp Substitució: Substitueix lamps with new F32T8 fluorescent lamps when they reach the end of their life or begin to flicker excessively. Always disconnect power before replacing lamps.
- Inspecció del cablejat: Periodically inspect wiring connections for any signs of wear, fraying, or loose terminals. Address any issues promptly after disconnecting power.
