• 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 (see figure5 on the
next page) identify the power cord negative lead.

• 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.

• 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.

• 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.

1. Cut the DC output cord to the length needed.

2. Strip the jacket to expose 3/16 inches (5 mm) of the conductors.

3. Slide the leads into the supplied 2-pole captive screw plug and secure them, using a

small screwdriver.
