SAFETY REQUIREMENTS
The warnings or cautions that must be observed for the hardware
described in this manual are listed below in English, German, French, and
Spanish.
WARNING Only qualified personnel should install or
service this unit.
VORSICHT Diese Einheit darf nur von qualifizierten Fach-
leuten installiert oder gewartet werden.
DANGER L’installation et la maintenance de cet appar-
eil sont réservées à un personnel qualifié.
AVISO Sólo el personal cualificado debe instalar o
dar mantenimiento a esta unidad.
WARNING If theDLM6C-AA is to be placed on a shelving
unit, the shelf must be able to support 75
pounds.
If the DLM6C-AA is to be rack mounted, care
must be taken to ensure that the rack used will
support the unit and that the rack remains
stable with the DLM6C-AA installed.
If the rack is not secured to the floor, it is
recommended that the chassis be installed in
the bottom half of the rack. This prevents the
rack from being top heavy.
Two people may be required to lift the chassis
into place.

Safety Requirements
DLM6C-AA Overview and Setup Guide xvii
VORSICHT Wenn der DLM6C-AA auf einem Regal plaziert
werden soll, muß das Regal eine Last von ca.
34 Kilogramm (75 Pfund) unterstützen können.
Wenn der DLM6C-AA dagegen in einem
Einschubgehäuse installiert werden soll, muß
der Einschub die Einheit stützen können und
nach der Installation des DLM6C-AA stabil
bleiben. Wenn das Einschubgehäuse nicht am
Boden befestigt ist, wird die Installation im
unteren Teil des Gehäuses empfohlen, da
andernfalls der obere Teil zu schwer und nicht
stabil sein könnte. Eventuell sind zwei
Personen zum Einsetzen in das Gehäuse
erforderlich.
DANGER Si l'appareil DLM6C-AA doit être monté sur un
support, celui-ci doit pouvoir accepter un poids
de 34 kg. Si l'appareil doit être monté sur un
rack, assurez-vous que celui-ci est prévu pour
cela et qu'il restera stable une fois l'appareil
installé. Si le rack n'est pas fixé au sol, il est
recommandé d'installer le châssis dans la
partie inférieure du rack, pour ne pas
surcharger la partie supérieure. Prévoir deux
personnes pour insérer le châssis.
AVISO Si el DLM6C-AA se va a colocar en una unidad
de estantes, el estante deberá ser capaz de
aguantar 34 kg. Si el DLM6C-AA se va a
montar en bastidor, es preciso asegurarse de
que el bastidor tenga capacidad para aguantar
la unidad y de que permanecerá estable una
vez instalado el DLM6C-AA. Si el bastidor no
está fijado al suelo, se recomienda instalar el
chasis en la mitad inferior del bastidor, para
evitar que la parte superior del mismo se
venza por exceso de peso. Es conveniente
pedir la ayuda de otra persona para colocar el
chasis en su lugar.

Safety
xviii DLM6C-AA Overview and Setup Guide
WARNING To reduce the risk of electric shock or energy
hazards:
Ensure the branch circuit overcurrent
protection is rated at a minimum of 25 A.
Use the 10 AWG solid copper conductors only.
Ensure that a readily accessible disconnect
device that is suitably approved and rated, is
incorporated in the field wiring.
To be installed in a restricted access area in
accordance with the NEC or the authority
having jurisdiction.
VORSICHT Um Elektroschock und Stromgefahr zu
vermeiden: Stellen Sie sicher, daß die
Überstromschutzeinrichtung des
Verzweigungsstromkreises auf mindestens 25
A eingestellt ist. Verwenden Sie nur 10
AWG-Kupferhalbleiter. Ein genehmigtes, leicht
zugängliches Trenngerät mit angemessener
Strom- und Spannungsleistung muß in der
Feldverkabelung integriertsein.Die Installation
darf nur in einem Gebiet mit begrenztem Zutritt
entsprechend dem NEC oder der zuständigen
rechtlichen Behörde erfolgen.
DANGER Pour réduire les risques de choc électrique et
de tout danger afférent : assurez-vous que la
protection du circuit accepte au minimum 25 A.
N'utilisez que des conducteurs en cuivre type
10 AWG. Vérifiez qu'un appareil de
déconnexion adapté et facilement accessible
soit installé sur la câblage. L'installation doit
être faite conformément aux réglements en
vigueur dans le pays concerné.
