Safety

Safety

(English)

WARNING: This equipment services power from

more than one source. The output receptacles may
have voltage even when the unit is unplugged.

UPSs present a different safety issue than most
electrical equipment because unplugging the UPS
puts it into backup mode. Unplugging the UPS does
not remove the electrical charge. To ensure that the
UPS is off, turn the power switch OFF before
unplugging the UPS from the wall outlet.

CAUTION: Operating this equipment without

proper grounding may present a risk of electrical
shock.

Do not use A C adaptors with only tw o conductors to
connect the input line cord to the wall socket as this
will not connect the earth ground to the equipment.

WARNING: Dangerous voltages are present within

this unit! There ar e no user -serviceable parts inside .
Any repairs or modifications by the user may result
in out-of-warranty repair charges, unsafe electrical
conditions, or violation of electrical code.

Do not remove the cov er. All repairs should be done
by qualified service personnel. Voltages inside the
UPS may be lethal. Internal components are
powered even when the power switch is in the OFF
position. Even with the battery disconnected and the
unit unplugged, energy is stored in high voltage
capacitors and represents a severe shock hazard.

débranchement n'élimine pas la charge électrique.
Pour s'assurer que l'UPS est hors tension, mettre
l'interrupteur d'alimentation sur ARRÊT (OFF) avant
de débrancher l'UPS de la prise murale.

ATTENTION : Si cet équipement fonctionne sans

être correctement mis à la terre, un risque de choc
électrique peut en résulter.

Ne pas utiliser d'adaptateurs CA n'ayant que deux
conducteurs pour brancher le cordon d'alimentation
dans la prise murale, car l'équipement ne serait pas
mis à la terre.

AVERTISSEMENT : Cet équipement renferme des

tensions dangereuses! Il ne contient aucune pièce
réparable par l'usager. Toutes réparations ou
modifications effectuées par l'usager peuvent
entraîner des frais de réparation non couverts par la
garantie, un danger électrique ou l'infraction à un
code électrique.

Ne pas enlever le couvercle. Confier toutes les
réparations à un personnel d'entretien qualifié. Les
tensions présentes dans l'UPS peuvent être
mortelles. Les composants internes de l'unité sont
sous tension, même lorsque l'interrupteur
d'alimentation est sur ARRÊT (OFF). Même lorsque

ADVERTENCIA: Este equipo suministra

alimentación desde más de una fuente. Los
tomacorrientes de salida pueden tener voltaje aun
cuando la unidad esté desenchufada.

Las UPS (fuentes de alimentación ininterrumpibles)
cuentan con una característica de seguridad diferente
a la mayoría de los equipos eléctricos, ya que al
desenchufarse, quedan en el modo de reserva. Al
desenchufar una UPS no se elimina la carga
eléctrica. Para cerciorarse de que una UPS esté
apagada, gire el interruptor de alimentación a la
posición APAGADO (OFF) antes de desenchufar el
UPS del tomacorriente mural.

PRECAUCION: El hacer funcionar este equipo sin

la conexión a tierra adecuada representa un riesgo
de descargas eléctricas.

No utilice adaptadores de CA con sólo dos
conductores para conectar el cable de la línea de
entrada al enchufe mural debido a que éste no
conectará el equipo a tierra.

ADVERTENCIA: ¡Esta unidad tiene voltajes

peligrosos!. En su interior no hay piezas que pueda
reparar el usuario. Las reparaciones o
modificaciones hechas por el usuario pueden dar
como resultado cargos de reparación no cubiertos
por la garantía, y producir situaciones de riesgo
eléctrico o violación de los códigos eléctricos.

No retire la cubierta. Todas las reparaciones deben
ser realizadas por personal de servicio calificado.
Los voltajes del interior de las UPS pueden ser
mortales. Los componentes internos tienen
electricidad aun cuando el interruptor esté en la
posición APAGADO (OFF). Incluso si la batería está
desconectada y la unidad desenchufada, se almacena
energía en capacitores de alto voltaje, lo cual
representa un peligro grave de descarga.

Theory of Operation

Theory of
Operation

AC Power Mode

Battery Backup
Mode

The ON Series UPS has two operating modes:
Conditioned AC Power and Conditioned Battery
Backup.

When AC utility power is present and within the
correct voltage range, the UPS provides fully
conditioned power:

• Computer based equipment is protected from
harmful transient voltage spikes and other
electrical noise.

• UPS detector circuits continuously monitor the
utility power for blackout, low voltage, and
overvoltage events.

During extended low voltage periods the UPS uses
ONBoost™, a voltage boosting capability, which
keeps equipment functioning properly without
depleting battery power . When a line sag is detected,
ONBoost raises the output voltage to keep it within
an acceptable range without depleting the battery.

In an over- or under-voltage situation, the detector
circuits determine that utility AC power is no longer
in an appropriate voltage range. The UPS switches to
battery power to supply continuous conditioned
power.

While in backup, detector circuits monitor the return
of utility AC power. The UPS synchronizes with the
utility’s frequency when utility AC power is
available. A four- to five-second waiting period
ensures that the return of utility power is more than
momentary. If no further interruption occurs, the
UPS switches to conditioned utility power. The
equipment is supplied continuously with
conditioned power even when running in battery
backup mode.

Switch

If the battery becomes exhausted while maintaining
the load, battery backup terminates and the UPS
output turns off. A low battery warning is sounded
and transmitted via the communications port
approximately two minutes prior to termination of
battery backup. The UPS monitors the line and
provides output when utility power is restored to
normal operating range.

Theory of Operation

Inrush T olerance

The UPS load meter may initially display “c8”
during the computer power-up sequence due to
momentary current surges. The display returns to
“99” or less as long as the load of the running
equipment is at 100 percent or less.

Output Overload
Protection

ON Series User Instruction Manual 9

During normal operation, electronic output overload
protection is active. If the output is loaded to more
than 105 percent of the UPS rating, battery power to
the UPS is not available. The digital display for
output overload is “c8”. If the output load exceeds
125 percent, the output turns off completely after
two seconds and the digital display reads “c9”. To
reset, turn the UPS OFF, remove some of the load,
then turn the UPS ON. (For GS compliance: The
power distribution system for all models is type TN.)

Theory of Operation

Interface Connector DIP Switches

Input Protector

A grossly overloaded UPS trips the rear panel circuit
breaker. The front panel display reads “c1”. To reset
the circuit breaker, push the button in.

• If the circuit breaker trips repeatedly following
reset, unplug the equipment from the UPS output
receptacles and reset the circuit breaker once
again.

• If operation appears to be normal, check the total
equipment load. Add your equipment to the
output one device at a time. Check the front
panel display after each device is powered ON.

• If the circuit breaker trips with nothing plugged
into the output receptacles, there may be an
internal problem with the UPS. Call ONEAC
Technical Support for assistance (refer to
page 1).

power during use and may overload the UPS.

Testing

ON Series User Instruction Manual 11

Before connecting the UPS to other equipment, plug
the UPS into an A C-po wered wall outlet and turn the
UPS ON. When selecting a location for your UPS, be
sure that the unit is near the wall outlet and is easily
accessible. After the self-tests are completed, the
digital display on the front should read “00” and the
“% LOAD” light should be on. If the digital display
reads differently, refer to System Status Codes
beginning on page 63. When the digital display reads
“00”, the UPS is ready for use.

NOTE: If the battery is not fully char ged, the digital

display may read “c4”. This condition may exist for
4 – 12 hours if a unit has been stored.

Long Term
Storage

The percent of UPS capacity in use is displayed on
the front panel of the UPS. As long as the display
reads “99” or less when the AC line is present and
your equipment is running, the UPS is not
overloaded. If the front panel displays “c8” or “c9”,
the unit is overloaded. Remov e some of the load until
the front panel displays “99” or less.

Improper long-term UPS storage may damage the
UPS battery and invalidate the battery warranty.
Unplugging a UPS from its AC utility power source
for an extended period of time results in lost battery
charge. Restoration of charge to maximum capacity
requires 24 – 48 hours. For standard models, the
System code may show a “c4” for 2 – 4 hours after
utility power is restored. For extended runtime
models, the system code “c4” may show for 2 – 4
hours per battery cabinet.

To keep the battery enclosure fully charged and to
maximize the life of the battery , plug the UPS into an
outlet while it is in storage. If the UPS is stored
without power access, plug it into a po wer source for
24 hours at least once every 4 – 6 months.

ATTENTION: If the storage temperature is greater

than 30
