unit. When removing the unit remove the grounding connection only after the unit is switched off and
unplugged.
VORSICHT! Zur Vermeidung von lebensgefährlichem Stromschlag muss vor Einschalten des Geräts
sichergestellt werden, dass das Rack vorschriftsmäßig geerdet wurde. Bei Entnahme des Geräts ist dieses
zuerst auszuschalten und von der Stromversorgung zu trennen, bevor der Erdungsanschluss entfernt wird.
DANGER: Pour éviter l'électrocution, assurez-vous que le rack a bien été mis à la terre avant de mettre
l'unité en marche. Lors du retrait de l'unité, retirer le raccordement de terre seulement après avoir mis
l'unité à l'arrêt et l'avoir débranchée.
CAUTION: This product relies on the building's electrical installation for short-circuit (overcurrent)
protection. Ensure that a fuse or circuit breaker no larger than 120 VAC, 20 A U.S. (240 VAC, 20 A
international) is used on the phase conductors (all current-carrying conductors).
