Installation

» Note Security: This product must be installed within a restricted access location where access is through the use a tool, lock and key, or other means of security, and is controlled by the authority responsible for the location. This product must be installed and maintained only by qualified technicians.

» Note de sécurité: Cet équipement doit être installé dans un local dont l'accès est protégé soit physiquement (cadenas, clé, …), soit par un système de contrôle d'accès (clé électronique, code, …). Tous ces moyens doivent être gérés et contrôlés par le responsable du site. L'installation et l'entretien de cet équipement ne doivent être confiés qu'à des techniciens qualifiés.

» Note: An appropriate disconnect device shall be incorporated in the building installation wiring.

» Note: Un dispositif de déconnexion approprié doit être intégré au câblage de l'installation du bâtiment.

» Note: The DC input should be protected by an external 2A DC rated slow Blow Fuse suitable for branch circuit protection, at the power supply or within the building circuitry. The input DC power current limiting fuse circuit is provided for by the end user, and is required for unit operation in compliance with safety agency approvals.

» Note: L'alimentation en courant continu doit être protégée par un fusible externe de 2 A, adapté à la protection des circuits de dérivation, soit au niveau local, soit au niveau de l'installation générale du bâtiment. Cette protection, requise pour le bon fonctionnement de l'équipement et conforme aux normes fixées par les organismes de sécurité, doit être fournie par l'utilisateur.

Ensure conditions A-E will be met by the installation before proceeding.

A. Elevated Operating Ambient - If installed in a closed or multi-unit rack assembly, the operating ambient temperature of the rack environment may be greater than room ambient. Therefore, consideration should be given to installing the equipment in an environment compatible with the maximum ambient temperature (TMA) specified by the manufacturer.
B. Reduced Air Flow- Installation of the equipment in a rack should be such that the amount of air flow required for safe operation of the equipment is not compromised.
C. Mechanical Loading - Mounting of the equipment in the rack should be such that a hazardous condition is not achieved due to uneven mechanical loading.
D. Circuit Overloading - Consideration should be given to the connection of the equipment to the supply circuit and the effect that overloading of the circuits might have on overcurrent protection and supply wiring. Appropriate consideration of equipment nameplate ratings should be used when addressing.
E. Reliable Earthing - Reliable earthing of rack-mounted equipment should be maintained. Particular attention should be given to supply connections other than direct connections to the branch circuit (e.g. use of power strips).

» Caution: DANGER! FIRE HAZARD! DO NOT LEAVE AN UNCONNECTED WIRE EXPOSED! DO NOT CONNECT THE UNIT TO ANY OTHER EQUIPMENT UNTIL YOU KNOW THE UNIT POWERS UP CORRECTLY!

» Attention: DANGER! INCENDIE ! NE LAISSEZ PAS LES FILS NON CONNECTÉS EXPOSÉS ! NE PAS connecter l'appareil à tout autre équipement avant de savoir que l'appareil soit correctement!

Connection to DC Power

Run two sets of wire to the SiteBoss power input. For A/B redundant systems one circuit should be feed from the A plant distribution, and one circuit from the B plant distribution. If A/B redundant power feeds are not required ignore all instructions for B side power feeds.

Ensure the rack that the unit is mounted in is properly grounded. Measure the resistance between the rack and building steel, aisle ground, or other properly grounded locations. The resistance should be <1 ohm. If this is not the case, connect the chassis ground point on the lower right hand corner of the A71 power supply to the facilities ground system.

» Ensure that the upstream circuit protection device for both circuits is off or removed before proceeding. Confirm this with a digital multi-meter. It should read 0V between the + and - feed cables in each circuit.

» Veillez à ce que le dispositif de protection des deux circuits amonts soit éteint ou retiré avant de poursuivre. Vérifiez le avec un multimètre numérique: la tension, entre les + et - des câbles d'alimentation de chaque circuit, doit être 0V.

Battery Warning

» CAUTION: THERE IS A RISK OF EXPLOSION IF THE BATTERY IS REPLACED BY AN INCORRECT TYPE. Replace with batteries of the same type or as recommended by the manufacturer. Dispose of used batteries according to the instructions.

» ATTENTION: II Y A DANGER D’EXPLOSION SI LA BATTERIE ORIGINALE EST REMPLACEE PAR UNE BATTERIE D'UN AUTRE MODELE. N'UTILISER QUE DES BATTERIES DU MEME TYPE OU SUIVRE LES RECOMMANDATIONS DU CONSTRUCTEUR. LES BATTERIES USAGEES DOIVENT ETRE MISES AU REBUT SELON LES INSTRUCTIONS DU CONSTRUCTEUR.
