of 1.5 A, or 56/48 VDC (PoE) and a minimum of 0.8/0.35 A.
• Si ce produit ne dispose pas de sa propre source d’alimentation électrique, il doit
être alimenté par une source d’alimentation de classe 2 ou LPS et paramétré à
12 V et 1.5 A minimum, ou 56/48VDC (PoE) et 0.8/0.35 A minimum.
• The installation must always be in accordance with the applicable provisions of
National Electrical Code ANSI/NFPA 70, article 725 and the Canadian Electrical
Code part 1, section 16. The power supply shall not be permanently fixed to
building structure or similar structure.
• Cette installation doit toujours être en accord avec les mesures qui s’applique
au National Electrical Code ANSI/NFPA 70, article 725, et au Canadian Electrical
Code, partie 1, section 16. La source d’alimentation ne devra pas être fixée de
façon permanente à une structure de bâtiment ou à une structure similaire.
• Power supply voltage polarity is critical. Incorrect voltage polarity can damage
the power supply and the unit. The ridges on the side of the cord identify the
power cord negative lead (see figure 7 on page 11).
• La polarité de la source d’alimentation est primordiale. Une polarité incorrecte
pourrait endommager la source d’alimentation et l’unité. Les stries sur le côté
du cordon permettent de repérer le pôle négatif du cordon d’alimentation (voir
figure 7).
• To verify the polarity before connection, plug in the power supply with no load
and check the output with a voltmeter.
• Pour vérifier la polarité avant la connexion, brancher l’alimentation hors charge et
mesurer sa sortie avec un voltmètre.
• The length of the exposed (stripped) copper wires is important.
The ideal length is 3/16 inch (5 mm). Longer bare wires can short together.
Shorter wires are not as secure in the connectors and could be pulled out.
• La longueur des câbles exposés est primordiale lorsque l’on entreprend de les
dénuder. La longueur idéale est de 5 mm (3/16 inches). S’ils sont un peu plus
longs, les câbles exposés pourraient se toucher et provoquer un court circuit.
S’ils sont un peu plus courts, ils pourraient sortir, même s’ils sont attachés par
les vis captives.
• Do not tin the wires. Tinned wires are not as secure in the captive screw
terminals and could pull out.
• Ne pas étamer les câbles. Les câbles étamés ne sont pas aussi bien fixés dans
les borniers à vis et pourraient s’arracher.
• Unless otherwise stated, the AC/DC adapters are not suitable for use in air
handling spaces or in wall cavities.
• Sauf mention contraire, les adaptateurs AC/DC ne sont pas appropriés pour une
utilisation dans les espaces d’aération ou dans les cavités murales.
