un court-circuit.

Bevor nach einem FRU-Austausch der Computer wieder angeschlossen wird,

muß sichergestellt werden, daß keine Schrauben, Federn oder andere Kleinteile

fehlen oder im Gehäuse vergessen wurden. Der Computer muß geschüttelt und auf

Klappergeräusche geprüft werden. Metallteile oder-splitter können Kurzschlüsse

erzeugen.

Prima di accendere l’elaboratore dopo che é stata effettuata la sostituzione di una

FRU, accertarsi che tutte le viti, le molle e tutte le altri parti di piccole dimensioni

siano nella corretta posizione e non siano sparse all’interno dell’elaboratore.

Vericare ciò scuotendo l’elaboratore e prestando attenzione ad eventuali rumori;

eventuali parti o pezzetti metallici possono provocare cortocircuiti pericolosi.

Antes de encender el sistema despues de sustituir una FRU, compruebe que

todos los tornillos, muelles y demás piezas pequeñas se encuentran en su sitio

y no se encuentran sueltas dentro del sistema. Compruébelo agitando el sistema

y escuchando los posibles ruidos que provocarían. Las piezas metálicas pueden

causar cortocircuitos eléctricos.

Safety notice 6

DANGER

To avoid shock, do not remove the plastic cover that protects the lower part of the

inverter card.

An d’éviter tout risque de choc électrique, ne retirez pas le cache en plastique

protégeant la partie inférieure de la carte d’alimentation.

Aus Sicherheitsgründen die Kunststoffabdeckung, die den unteren Teil der

Spannungswandlerplatine umgibt, nicht entfernen.

Per evitare scosse elettriche, non rimuovere la copertura in plastica che avvolge la

parte inferiore della scheda invertitore.

Para evitar descargas, no quite la cubierta de plástico que rodea la parte baja de la

tarjeta invertida.

Safety notice 7

DANGER

Though the main batteries have low voltage, a shorted or grounded battery can

produce enough current to burn personnel or combustible materials.

Bien que le voltage des batteries principales soit peu élevé, le court-circuit ou la

mise à la masse d’une batterie peut produire sufsamment de courant pour brûler

des matériaux combustibles ou causer des brûlures corporelles graves.

Obwohl Hauptbatterien eine niedrige Spannung haben, können sie doch bei

Kurzschluß oder Erdung genug Strom abgeben, um brennbare Materialien zu

entzünden oder Verletzungen bei Personen hervorzurufen.

Sebbene le batterie di alimentazione siano a basso voltaggio, una batteria in

corto circuito o a massa può fornire corrente sufficiente da bruciare materiali

combustibili o provocare ustioni ai tecnici di manutenzione.

Aunque las baterías principales tienen un voltaje bajo, una batería cortocircuitada

o con contacto a tierra puede producir la corriente suciente como para quemar

material combustible o provocar quemaduras en el personal.

Important information about replacing RoHS compliant FRUs

RoHS, The Restriction of Hazardous Substances in Electrical and

Electronic Equipment Directive (2002/95/EC) is a European Union legal

requirement affecting the global electronics industry. RoHS requirements

must be implemented on Lenovo products placed on the market after

June 2006. Products on the market before June 2006 are not required to

have RoHS compliant parts. If the original FRU parts are non-compliant,

replacement parts can also be non-compliant. In all cases if the original

FRU parts are RoHS compliant, the replacement part must also be RoHS

compliant.
