defined in IEC 950. Figure 8 provides the pin information for the DC power connector. To connect the DC power cable to the drive, simply insert the cable end into the drive’s DC power connector.

4.Schließen Sie das SCSI-Kabel an den SCSI-Steckverbinder des Laufwerkes an. Das Kabel darf nicht gedehnt oder gedrückt werden und es darf den Luftstrom zur Kühlung des Systems nicht behindern.

Das Laufwerk wird über einen 4-poligen, neben dem SCSI- Anschluß befestigten Steckverbinder mit Gleichstrom ver- sorgt. Der Ausgang eines Netzteils muß SELV (safety extra low voltage) nach IEC 950 entsprechen. Abbildung 8 zeigt die Steckerbelegung für den Gleichstromanschluß. Zum Anschluß des Gleichstromkabels an das Laufwerk das Kabelende in den Gleichstromanschluß des Laufwerkes stecken.
