Note. Signal ground on the power control board (PCB) and the head and disc assembly (HDA) are connected together in this drive and you cannot separate them. The equipment in which you have mounted the drive is connected directly to the HDA and PCB without electrically isolating shock mounts. Maximizing the conductive contact area between HDA ground and system ground may reduce radiated emissions.

If you do not want the system chassis to be connected to the HDA/PCB ground, you must provide a nonconductive (electrically isolating) method of mounting the drive in the host system. This may increase radiated emissions and is the system designer’s responsibility.

Hinweis:

Die Signalerde auf der Stromregelungskarte (PCB) und der Kopf- und Festplatteneinheit (HDA) sind in diesem Laufwerk miteinander verbunden und können nicht getrennt werden. Das Gerät, in das Sie das Laufwerk eingebaut haben, ist ohne elektrisch isolierende Stoßdämpfer direkt an die HDA und PCBangeschlossen. Die elektromagnetische Strahlung kann reduziert wer- den, indem Sie eine möglichst große leitende Kontak- fläche zwischen der HDA-Erdung und der Systemerdung vorsehen.

Wenn Sie das Systemgehäuse nicht an die HDA/PCB- Erdung anschließen wollen, müssen Sie das Laufwerk auf nichtleitende Weise (galvanisch isoliert) im Host-Sys-
