Safety Notices
Before you access any components located inside the unit, remove the power cable and wait until
all the status LEDs turn off.
Only qualified service personnel are to access the inside of the unit.
An AC power cord is provided with a grounded attachment plug for the external power supply. To
avoid electrical shock, always use the AC power cord and plug with a properly grounded outlet
(connected to earth).
To maintain safety compliance, ensure the AC power cord has the appropriate safety approvals for
the country in which the equipment is to be installed. For North America, the AC power cord must
be a UL listed SJT NEMA 5-15 equivalent or better.
When connected to an outdoor camera, the screen of the camera’s coaxial cable must to be
properly grounded (connected to earth). Cable distribution systems are subject to the National
Electrical Code (NEC) in the United States and the Canadian Electrical Code (CEC) in Canada.

Mandatory Regulations
Avis de sécurité
Avant d’accéder aux composantes internes de l’unité, vous devez enlever le câble de pouvoir et
attendre que toutes les lumières d’état (‘STATUS LED’) de l’unité soient éteintes.
Seulement le personnel de service qualifié a le droit d’accéder l’intérieur de l’unité.
Le câble de pouvoir AC est fournie avec un câble de mise à terre pour le bloc d’alimentation
électrique. Pour éviter tout choc, utilisez toujours le câble de pouvoir AC relié avec la prise de
courant adéquate (contenant une mise à terre).
Pour maintenir votre conformité de sécurité, assurez-vous que le câble de pouvoir AC a obtenu les
approbations de sécurité applicables pour le pays ou l’installation est faites. Pour l’Amérique du
Nord, le câble de pouvoir AC doit avoir une certification UL SJT NEMA 5-15, équivalente ou
meilleur.
Lorsque relié à une caméra installée à l’extérieur, l’enveloppe du câble coaxial de la camera doit
être mise à terre de façon adéquate. Les systèmes de distribution câblés sont sujet au code
électrique National (NEC) au États-Unis et au code électrique Canadien (CEC) au Canada.
Fuse
CAUTION: Double pole / neutral fusing.
Fusible
ATTENTION : c’est une fusible à double pôle.
Ground Connection
Install a protective earth conductor if the equipment is connected to a telecommunication network
or a cable distribution system. There is a grounding stud on the back of the unit. The grounding
method is described in “Ground Connection” on page 28.
Connection de mise à terre
Installez un câble de mise à terre si l’unité est reliée à un réseau de communication ou un système
de distribution câblé. Il y a un goujon de mise à terre à l’arrière de l’unité. La méthode de mise à
terre est décrite à la section « Ground Connection » à la page 28.
Installation Location
It is recommended that the unit is installed in a restricted access location. If not possible, the unit
may be installed in a non-restricted location but it MUST be mounted so that the back of the unit
(where cables are routed) is only accessible from a restricted access location.
Endroit ou l’installation est permise
On recommande que l’unité soit installée dans un endroit à accès restreint.
Si cela n’est pas possible, l’unité peut être installé dans un endroit à accès non restreint
seulement si elle est installée de façon à ce que le derrière de l’unité (ou les câbles sont
dirigés) ne soit pas accessible.
