Notes on rack-mounting the unit

 

If you install the AD8HR along with another AD8HR or other 
device in a rack that is not well ventilated, the temperature inside 
the rack may rise due to the heat generated from the devices and the 
devices may be unable to perform properly. When you rack-mount 
the unit, be sure to keep a gap of 1U (4.5cm) above and below the 
unit for better ventilation. Also, install the ventilation panels in 
these gaps or remove the partition panels.

If the temperature inside the rack is expected to be 40°C or higher 
(in this case, the room temperature is generally about 30°C or 
higher), install the fan kit on the top shelf of the rack, and install the 
ventilation panels between devices or remove the partition panels. 
The fan kit must generate a wind of 1.6m

Anmerkungen zum Rackeinbau des Geräts

 

Wenn Sie den AD8HR gemeinsam mit einem anderen AD8HR oder 
einem Gerät mit mangelhafter Lüftung in ein Rack einbauen, könnte 
die Temperatur im Innern des Racks rapide ansteigen und Ausfälle der 
vorhandenen Geräte verursachen. Lassen Sie über und unter Geräten 
in einem Rack jeweils 1HE (4,5cm) frei, um eine ausreichende 
Luftzirkulation zu gewährleisten. In diesen Öffnungen müssen 
Lüftungsblenden angebracht werden. Außerdem sind eventuell 
vorhandene Trennplatten zu entfernen.

Wenn die Temperatur im Innern des Racks die 40°C-Marke zu 
übersteigen droht (was der Fall ist, wenn die Raumtemperatur 
mindestens 30°C beträgt), müssen Sie ganz oben im Rack eine 
Lüftereinheit und zwischen den Geräten Lüftungsblenden 
einbauen. Trennplatten zwischen diesen Partien müssen entfernt 
werden. Die Lüftereinheit muss einen Luftstrom von mindestens 
1,6m

Remarques concernant l’installation de l’unité dans un rack

 

Si vous installez l’AD8HR dans le même rack qu’un deuxième 
AD8HR ou tout autre dispositif avec une ventilation autonome 
plutôt limitée, la température au sein du rack pourrait très vite 
monter à des valeurs qui empêchent les unités de fonctionner 
correctement. De ce fait, pour le montage en rack, il convient de 
laisser un espace d’1U (4,5cm) au-dessus et en dessous de tels 
dispositifs pour assurer une bonne circulation d’air frais. De plus, il 
faut couvrir les ouvertures ainsi laissées avec des panneaux de 
ventilation. Retirez toute cloison éventuellement présente entre 
deux unités.

Si la température au sein du rack risque de monter au-delà de 40°C 
(auquel cas la température ambiante s’élève à 30°C ou plus), 
installez un kit de ventilation en haut du rack et des panneaux de 
ventilation entre les unités. Retirez en outre les cloisons qui les 
séparent. Le kit de ventilation doit générer un flux d’air supérieur à 
1,6m

Notas acerca de la instalación en rack de la unidad

 

Si instala el AD8HR junto con otro AD8HR u otro dispositivo en 
un armario rack que no esté correctamente ventilado, la 
temperatura en el interior del armario puede elevarse debido al 
calor generado por los propios dispositivos y afectar al correcto 
funcionamiento de los mismos. Cuando instale la unidad en rack, 
asegúrese de dejar una separación de 1U (4.5cm) por encima y por 
debajo de la unidad con el fin de conseguir una correcta 
ventilación. Además, instale los paneles de ventilación en estas 
separaciones o elimine los paneles de partición.

Si se calcula que la temperatura en el interior del rack sea de 40°C o 
más (en este caso, cuando la temperatura de la habitación es de 
30°C o superior), instale el kit de ventilación en la parte superior 
del armario rack e instale los paneles de ventilación entre los 
dispositivos o elimine los paneles de división. El kit de ventilación 
debe generar un caudal mínimo de 1.6m
