•Vergewissern Sie sich, dass Netzteil, Stecker und Steckdose intakt sind.
•Nur, wenn der Stecker physisch von der Steckdose getrennt ist, können Sie
davon ausgehen, dass keine Spannung vorliegt.
•Falls keine Erdung angeschlossen ist, trennen Sie die PDU von der Steckdose,
bevor Sie ein Gerät anschließen, um die Gefahr elektrischen Schlags zu
verringern. Schließen Sie das automatische Netzumschaltgerät erst dann wieder
an, wenn Sie alle Geräte angeschlossen haben.
•Vermeiden Sie den Einsatz des Produkts unter ungeeigneten
Umgebungsbedingungen. (Über 80 % relative Feuchtigkeit, Nässe,
Raumtemperatur über 50 °C, Einsatz von Lösungsmitteln, entzündliche Gase,
