1.3 Installation

A visual inspection of this product for possible damage occurred during shipment is recommended before installation. It is your responsibility to ensure that qualified mechanical and electrical technicians install this product.

If there is danger of serious accident resulting from a failure or defect in this unit, power off the system and separate the electrical connection of the device from the system.

The unit is normally supplied without a power supply switch or a fuse. Use power switch and fuse as required.

Be sure to use the rated power supply voltage to protect the unit against damage and to prevent failure.

Keep the power off until all of the wiring is completed so that electric shock and trouble with the unit can be prevented.

Never attempt to disassemble, modify or repair this unit. Tampering with the unit may results in malfunction, electric shock or fire.

Do not use the unit in combustible or explosive gaseous atmospheres.

During putting equipment in hole on the metal panel while mechanical installation some metal burrs can cause injury on hands, you must be careful.

Montage of the product on a system must be done with it’s fixing clamps. Do not do the montage of the device with inappropriate fixing clamp. Be sure that device will not fall while doing the montage.

It is your responsibility if this equipment is used in a manner not specified in this instruction manual.

1.3 Installation

Vor Montage das Gerät visuell prüfen, ob das Gerät während der Beförderung beschädigt wurde.Die Montage und Inbetriebnahme muss durch geschultes Personal ausgeführt werden. Dies steht unter der Verantwortung des Käufers.

Falls aufgrund eines Fehlers oder einer Störung des Geräts eine Gefahr bestehen sollte, Spannungsversorgung abschalten und alle elektrischen Verbindungen zum Geräts entfernen.

Standardmäßig wird das Gerät ohne Netzschalter und ohne Sicherung ausgeliefert.

Bei Bedarf müssen diese vom Anwender selbst angebracht werden.

Es muss eine zum Gerät passende Versorgungsspannung verwendet werden, um Fehlfunktionen und Schäden zu vermeiden.

Um einen elektrischen Schock und ähnliche Unfälle zu vermeiden, darf das Gerät vor Abschluss der Verkabelung nicht mit Spannung versorgt werden.

An dem Gerät keine Veränderungen vornehmen, und das Gerät nicht reparieren.

Eingriffe am Gerät können fehlerhafte Funktion, Beschädigung des Geräts oder angeschlossener Geräte, elektrischen Schocks und Feuer auslösen.

Das Gerät darf unter keinen Umständen in der Nähe von brennbaren und explosiven Gasen verwendet werden.

Die Schalttafelausschnitte können scharfe Kanten aufweisen, welche bei der Montage des Geräts Schnittverletzungen verursachen können. Bitte treffen Sie die erforderlichen Vorsichtsmaßnahmen.

Es ist wichtig, dass das Gerät mit den mitgelieferten Befestigungsteilen montiertwird.

Das Gerät nicht mit ungeeigneten montieren. Achten Siedarauf, dass das Gerät während der Montage nicht herunterfällt.

Es unterliegt Ihrer Verantwortung, wenn das Gerät nicht wie in dieser Anleitung beschrieben, verwendet wird.

1.4 Garantie

2 Jahre Garantieschutz gegen Materialund Verarbeitungsfehler.

Diese Garantie wird mit dem Vorbehalt gewährleistet, dass der Kunde den in Garantieschein und Bedienungsanleitung erwähnten Pflichten nachkommt.

1.5 Instandhaltung

Das Gerät muss durch geschultes Personal gewartet werden. Vor dem Zugriff auf Innenteile, alle stromführenden Leitungen trennen. Gerät nicht mit auf Kohlenwasserstoff basierenden Lösungsmitteln (wie Benzin, Trichlorethylen etc.) reinigen. Das Reinigen mit diesen Lösungen kann die mechanische Sicherheit des Geräts vermindern. Verwenden Sie ein mit Ethylalkohol oder Wasser benetztes Tuch um das Plastikgehäuse außen zu reinigen.
