EXPLANATION OF GRAPHICAL SYMBOLS

The lightning flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user to the presence of uninsulated “dangerous voltage” within the product’s enclo- sure that may be of sufficient magni- tude to constitute a risk of electric shock to humans.

The exclamation point within an equi- lateral triangle is intended to alert the users to the presence of impor- tant operating and maintenance (ser- vicing) instructions in the literature accompanying the product.

EXPLICATION DES

SYMBOLES GRAPHIQUES

Le symbole éclair avec point de flèche

àl’intrérieur d’un triangle équilatéral est utilisé pour alerter l’utilisateur de la presence à l’intérieur du coffret de “voltage dangereux” non isolé d’ampleur suffisante pour constituer un risque d’elétrocution.

Le point d’exclamation à l’intérieur d’un triangle équilatéral est employé pour alerter les utilisateurs de la présence d’instructions importantes pour le fonctionnement et l’entretien (service) dans le livret d’instruction accompagnant l’appareil.

ERKLÄRUNG DER GRAPHISCHEN SYMBOLE

Der Blitz nach unten zeigendem Pfeil in einem gleichseitigen Dreieck weist den Benutzer auf das Vorhandensein einer

unisolierten,gefährlichen Spannung“ im Gehäuse ”hin, die stark sein kann, einer Person einen elektrischen Schlag zu versetzen.

Das Ausrufzeichen in einem gleichseitigen Dreieck weist den Benutzer auf wichtige Betriebs- und Wartungs- vorschriften in den beiliegenden Unterlagen des Gerätes hin.
