SCHEMA ELETTRICO / PARTS LIST MONITOR POLO 25" RCA USA

ATTENZIONEI Per effettuare qualsiasi misura di controllo nella sezione primaria alimentatore, usando voltmetro digitale o oscilloscopio, occorre separare ii monitor dalla rete tramite un TRASFORMATORE DI ISOLAMENTO, facendo comunque attenzione che la terra degli strumenti sla scollegata. Questa precauzione non e necessaria quando si effettuano le misure di controllo nella sezione monitor (deflessione e video), e sulle uscite secondarie dell'alimentatore. II trasformatore di isolamento deve avere queste caratteristiche: lngresso 110-120 V a.c., Uscita 110-120 V a.c. 200 W minimo

WARNING! Whenever voltage checks are to be made in the primary circuits of the power supppl , using a digital voltmeter or an oscilloscope, it is necessary to isolate the monitor from the mains supply by means of an ISOLATING TRANSFORMER also taking care that the Instruments are disconnected from earth. This precaution is not necessary when making measurements in the monitor section (deflexion and video), nor in the secondary circuits of the power supply. The isolating transformer for the above purpose should have following characteristics. Input 110-120 V a.c., Output 110-120 V a.c. 200 W minimun

ATENCIONI Para efectuar medidas de control en la secci6n primaria del alimentador, usando voltfmetro digital, o bien osciloscopio, es necesario separar el monitor de la red con un TRANSFORMADOR DE AISLAMIENTO, debiendo estar la tierra del instrumento conectada. De esta manera se evita que haya conexi6n directa a la red entre el instrumento y la seci6n primaria del alimentador, al estar el instrumento a la ti err a se evita danar cualquier componente y tener la maxima seguridad para el operador. Estas precauciones no son necesarias cuando se efectuan las medidas en la seci6n del monitor (deflexi6n video), y sobre la salida secundaria del alimentador. El transformador debe tener estas caracteristicas: Entrada 110-120 V a.c., Salida 110-120 V a.c. 200 W minimo

ATTENTION! Pour effectuer n'importe quelle mesure de controle dans la section primaire d 'alimentation, en utilisant un voltametre digital ou un oscilloscope, ii taut separer le moniteur du reseau au moyen d'un TRANSFORMATEUR D'ISOLEMENT, en faisant de toute fa9on attention ace que la prise de terre des instruments soit debranchee. Cette precaution n'est pas necessaire quand on effectue les mesures de controle dans la section moniteur (deflexions et video), et sur les sorties secondaires de l'alimentateur. Le transformateur d'isolement doit avoir les caracteristiques suivantes. Entree 110-120 V a.c., Sortie 110-120 V a.c. 200 W minimun

VORSICHTSMABNAHMENI Wenn Im Primarnetzteil Messungen mil Hilfe von digitalen Voltmetern und Oszilloskopen vorgenommen werden, ist es notwendig, den Monitor von der Hauptstromversorgung zu trennen. Dies sollte Ober einen TRENNTRANSFORMATOR erfolgen. Es isl unbedingt darauf zu achten, daB dann alle lnstrumente vom Erdpotential getrennt sind. Diese Vorkehrungen sind nicht notwendig, wenn Messungen auf der Monitorgrundplatine im Bereich der Ablenkung und Videoaufbereitung vorgenommen werden. AuBerdem sind obengenannte Vorkehrungen nicht notwendig im Sekundarbereich des Netzteils. Der Trenntransformator sollte folgende Eigenschaften haben. Eingang 110-120 V a.c., Ausgang 110-120 V a.c. 200 W
