Chapter 4: Operation
SYSTEM OVERVIEW
This Standby UPS protect s computers, servers, telecom systems, V oIP systems,
security systems, and a variety of electronic equipment from blackouts, brownouts,
overvoltages, and surges. During normal AC operation, the UPS will quietly and
confidently protect your system from power anomalies.
The UPS will charge the batteries with the UPS in the on or off position as long as
the UPS is plugged into the wall outlet and there is an acceptable AC voltage present
(95 - 140V AC). When a blackout, brownout, or an overvolt age condition occurs;
the UPS will transfer to the battery mode, the On Battery indicator will illuminate and
the audible alarm will sound once every five seconds indicating that the commercial
power is lost or unacceptable. When the commercial power returns or is at an
acceptable level, the UPS will automatically transfer back to the AC normal mode
and start recharging the batteries. During an extended outage when there is approximately two minutes of backup time remaining the audible alarm will sound
twice every five seconds. This Low Battery Warning is informing the user that they
should save all open files, turn off their computer and then turn off the UPS. When
the batteries reach the predetermined level the UPS will automatically shutdown
protecting the batteries from over discharging. Once the commercial power returns the UPS will automatically restart, providing safe usable power to the connected equipment and start recharging the batteries.

REPLACING THE BA TTERY
(QUALIFIED SERVICE PERSONNEL ONL Y)
Please read all of the WARNINGS and CAUTIONS before attempting to ser-
vice the batteries. Typical battery life is 3 to 5 years. Environmental factors
do affect battery life. High temperatures, poor utility power, and frequent,
short duration discharges have a negative impact on battery life.
WARNING! This UPS contains potentially hazardous voltages. Do not attempt to disassemble the UPS beyond the battery replacement procedure.
This UPS contains no user serviceable parts. Repairs and battery replacement must be performed by QUALIFIED SERVICE PERSONNEL ONL Y.
AVERTISSEMENT! Cet onduleur contient des tensions potentiellement
dangereuses. N'essayez pas de le démonter au-delà de la procédure de
remplacement d'une batterie. L'onduleur ne contient aucune pièce réparable
par l'utilisateur. SEUL UN TECHNICIEN QUALIFIÉ est autorisé à effectuer
les réparations et le remplacement d'une batterie.
CAUTION: Do not open or mutilate batteries. Released electrolyte is harmful
to the skin and eyes and may be toxic.
ATTENTION! Évitez d'ouvrir ou d'abîmer les batteries. L'électrolyte qu'elles
contiennent nuit à la peau et aux yeux et peut être toxique.
CAUTION: Do not dispose of batteries in a fire. The batteries may explode.
The batteries in this UPS are recyclable. Dispose of the batteries properly.
The batteries contain lead and pose a hazard to the environment and human
health if not disposed of properly. Refer to local codes for proper disposal
requirements or return the battery to the supplier .
ATTENTION! N'essayez jamais de vous débarrasser d'une batterie en la
brûlant. Elle risque d'exploser. Les batteries de cet onduleur sont recyclables.
Éliminez-les de manière appropriée. Les batteries contiennent du plomb et
posent un danger pour l'environnement et la santé si elles ne sont pas éliminées
de façon appropriée. Consultez les codes locaux pour savoir comment
correctement éliminer une batterie ou renvoyez-la au fournisseur.

CAUTION: The battery system can present a risk of electrical shock. These
batteries produce sufficient current to burn wire or tools very rapidly, producing molten metal. Observe these precautions when replacing the batteries:
1. Remove watches, rings, or other metal objects.
2. Use hand tools with insulated handles.
3. Wear protective eye gear (goggles), rubber gloves and boots.
4. Do not lay tools or other metal parts on top of batteries.
5. Disconnect the charging source prior to connecting or disconnecting the
battery terminals.
6. Determine if the battery is inadvertently grounded. If the battery is, remove
the source of the grounding. Contact with any part of a grounded battery
can result in an electrical shock. The likelihood of such shock will be reduced, if such grounds are removed during installation and maintenance.
ATTENTION! Les batteries peuvent entraîner le risque de choc électrique.
Elles produisent suffisamment de courant pour brûler très rapidement des fils
ou outils, les causant à fondre. Prenez les précautions suivantes lors du
remplacement d'une batterie.
1. Retirez votre montre, bagues ou autres objets métalliques.
2. Utilisez des outils à main à poignées isolantes.
3. Portez des lunettes de protection, des gants en caoutchouc et des bottes.
4. Ne placez jamais des outils ou autres objets en métal sur le dessus d'une
batterie.
5. Déconnectez la source d'alimentation avant de brancher ou de débrancher
les bornes d'une batterie.
6. Vérifiez si, par inadvertance, la batterie est toujours mise à la terre. Si
c'est le cas, supprimez la source de mise à terre. Le contact avec n'importe
quelle partie d'une batterie mise à la terre peut causer un choc électrique.
La suppression de dispositifs de mise à terre pendant l'installation et
l'entretien réduit le risque de chocs électriques.
BATTERY REPLACEMENT PROCEDURE
(QUALIFIED SERVICE PERSONNEL ONL Y)
PLEASE READ THE CAUTIONS AND W ARNINGS BEFORE A TTEMPTING
TO REPLACE THE BA TTER Y MODULE.
Hot-swappable batteries mean that the battery module can be replaced without
powering down the whole UPS system.
NOTE: If there is a power interruption while replacing the hot-swappable
battery module, with the UPS on, the load will not be backed up. To hot-swap
the battery module start with step number 6.
1. T urn off the equipment that is plugged into the output of the UPS.
2. T urn of f the UPS.
3. Unplug the UPS's AC power cord from the AC wall outlet.
4. Unplug the equipment from the output receptacles of the UPS.
5. Unplug all of the cables from the side panel of the UPS.
NOTE: No tools are required for removing or installing the battery door .
6. Grasp the battery door handle, slide the battery door outward, then lift upwards and set aside. (FIG . 1)
