Elite Installation GuideDisc Drive ST446452WContents Electrostatic discharge protection PrefaceImportant safety information and precautions Seagate takes all reasonable steps to ensure that its products are certifiable to currently accepted standards. Typical applica- tions of these disc drives include customer packaging and sub- system design. Safety agencies conditionally certify component assemblies, such as the Elite disc drive, based on their final acceptability in the end-use product. The subsystem designers are responsible for meeting these conditions of acceptability in obtaining safety-regulatory agency compliance in their end-use products and for certifying where required by law. A necessary part of meeting safety requirements is the provision for overcur- rent protection on drive SELV supply voltages Wichtige Sicherheitshinweise Elite 47 Installation Guide, Rev.
