SAVE THESE IMPORTANT UPS AND BATTERY

SAFETY INSTRUCTIONS

CONSERVER CES INSTRUCTION. CETTE NOTICE CONTIENT DES INSTRUCTIONS IMPORTANTES CONCERNANT LA SÉCURITÉ.

WARNING: Lethal voltages may be present within this unit even when it is apparently not operating. Observe all cautions and warnings in this manual. Failure to do so MAY result in serious injury or death. Refer UPS and battery service to qualified service

personnel. Keep unauthorized personnel away. Never work alone.

Clean UPS with only a dry cloth. Do not use liquids or aerosol cleaning fluids.

Only trained engineers authorized by Liebert should perform troubleshooting. If the UPS develops a fault, check the Alarm History and Input Disturbances recorded in the Event Log (LCD display menu item 3). See Alarm Messages, Meanings, and Corrective Actions in the

Appendix. Consult Liebert at 1-800-222-5877 for persistent unresolved problems. Do not use UPS if not performing to specification. Call Customer Service to replace fuses and diagnose cause of failure.

Batteries within the UPS provide standby power. During normal operation, the batteries automatically charge and the UPS control circuit automatically tests them. The UPS displays an alarm message if there is a battery charger problem or if the battery fails a test. Call Liebert at 1-800- 222-5877 for battery maintenance or replacement. When replacing batteries, use the same number and type of batteries.

Lead-acid batteries contain hazardous toxic materials. Handle, transport, and recycle in accordance with federal, state, and local regulations. DO NOT dispose of batteries by fire; they may explode. DO NOT open or mutilate batteries; released electrolyte is harmful to skin and eyes, maybe toxic. A battery presents a risk of electrical shock and high short circuit current. Lead-acid batteries present a risk of fire due to hydrogen gas generation. Observe these precautions when working on batteries:

∙Remove watches, rings, or other metal objects.

∙Wear rubber gloves and boots and use tools with insulated handles. DO NOT lay tools or metal parts on top of batteries.

∙Unplug UPS prior to connecting or disconnecting battery terminals. Remove battery fuses or open battery circuit breaker.

∙Remove all battery grounds. Contact with any part of a grounded battery may result in electrical shock.

∙DO NOT SMOKE near batteries. DO NOT cause flame or spark in battery area.

∙Touch a grounded metal surface to discharge static electricity from body before touching batteries.

CAUTION: This device complies with limits for a Class A computing device, pursuant to Part 15 of FCC rules. Operating this device in a residential area is likely to cause harmful interference to radio and TV reception which the user must correct at his own expense.

ADVERTISSEMENT: Des pièces sous alimentation seront laissées sans protection durant ces procedures d’entretien. Un personnel qualifié est réquis pour effectuer ces travaux.

Les fusibles à c.c. de la batterie d’accumulateurs opérent en tout temps à la tension nominale. La presence d’un fusible à c.c. brûlé indique, un problème serieux. Le remplacement de ce fusible, sans avoir determine les raisons de la defectuosite, peut entrainer des blessures ou des dommages serieux a I’équipement. Pour assistance, appeler le departement de service à la clientele de Liebert.

Les accumulateurs plomb-acide contiennent de la matière comportant un certain risque. Les accumulateurs doivent être manipulés, transportés, et recyclés en accord avec les lois fédérales, provinciales, et locales. Parce que le plomb est une substance toxique, les accumulateurs plomb-acide devraient être recyclés plutôt quéliminés. II ne faut pas brûIé le ou les accumulateurs. L’accumulateur pourrait alors explosé. II ne faut pas ouvrir ou endommager le ou les accumulateurs. L’électrolyte qui pourrait s’en échapper est dommageable pour la peau et les yeux. Un accumulateur représente un risque de choc électrique et de haut courant de court-circuit. Les accumulateurs plomb-acide présentent un risque d’incendie parce qu’ils génèrent des gaz à I’hydrogène. Lorsque des accumulateurs son manipulés, les mesures préventives suivantes devraient être observées:

∙Retirer toutes montre, bagues, ou autres objets métalliques.

∙Porter des gants et des bottes de caoutchouc et utiliser des outils avec manchon isolé. Ne pas déposer les outiles ou les pièces métalliques sur le dessus des accumulateurs.

∙Interrompre la source de charge avant de raccorder ou de débrancher les bornes de la batterie d’accumulateurs.

∙Déterminer si I’accumulateur est mis à la terre par erreur. Si oui, défaire cette mise à la terre. Tout contact avec un accumulateur mis à la terre peut se traduire en un choc électrique. La possibilitié de tels chocs sera reduite se de telles mises à la terre sont débranchées pour la durée de I’installation ou de I’entretien.

∙NE PAS FUMER lorsque près des accumulateurs. NE PAS produire de flammes ou d’étincelles près des accumulateurs.

∙Décharger toute électricité statique présente sur votre corps avant de toucher un accumulateur en touchant d’abord une surface métallique mise à la terre.

L’électrolyte est un acide sulfurique dilué qui est dangereux au contact de la peau et des yeax. Ce produit est corrosif et aussi conducteur électrlque. Les procédures suivantes devront être observées:
