Safety
This equipment was tested and complies with the
limits for a Class A digital device, pursuant to Part 15
of FCC Rules. These limits are designed to provide
reasonable protection against harmful interference
when the UPS is operating in a commercial
environment. The UPS generates, uses, and can
radiate radio frequency energy. If installation and use
is not in accordance with the instruction manual, it
may cause harmful interference to radio
communications.
ATTENTION: Operation of this equipment in a
residential area may cause harmful radio
communications interference. The user is
responsible for correcting the interference.
Safety
(English)
WARNING: This equipment services power from
more than one source. The output receptacles may
have voltage present 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 AC adaptors with only two 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 are 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.

Sicherheitshinweise
Do not remove the cover. 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.
Sicherheitshinweise
(Deutsch)
ACHTUNG: Dieses Gerät erhält seinen Strom von
mehr als einer Quelle. Die Ausgangssteckdosen
führen unter Umständen Spannung, selbst wenn der
Stecker des Gerätes ausgesteckt wurde.
Für USVs müssen andere Sicherheitsmaßnahmen als
für die meisten Elektrogeräte ergriffen werden, da
die USV durch Ausstecken in den Reservebetrieb
gebracht wird. Wenn der Stecker der USV
abgezogen wird, wird die elektrische Ladung
hierdurch nicht entfernt. Um sicherzustellen, daß die
USV ausgeschaltet ist, muß der Netzschalter auf
AUS (OFF) gestellt werden, bevor der Stecker der
USV aus der Wandsteckdose gezogen wird.
VORSICHT: Durch Betreiben dieses Gerätes ohne
ordnungsgemäße Erdung können Elektroschocks
riskiert werden.
Keine Wechselstromadapter mit nur zwei
Stromleitern verwenden, um das Netzkabel an die
Wandsteckdose anzuschließen, weil das Gerät
hierdurch nicht an die Erde angeschlossen wird.
ACHTUNG: In diesem Gerät sind gefährliche

AVERTISSEMENT: Cet équipement est alimenté
par plus d'une source. Des tensions peuvent
être présentes aux prises de sortie, même
lorsque l'unité est débranchée.
Le problème de sécurité sur l'UPS diffère de celui de
la plupart des équipements électriques, car lorsqu'il
est débranché, il se met en mode de réserve. Son
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

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.

Theory of Operation
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

AC Power Mode
When AC input 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® technology to conserve battery power.
6
ON Series 3.3-5.0 kVA User Instruction Manual
Theory of Operation
When a line sag is detected, ONBoost raises the
output voltage to keep it within an acceptable range.
NOTE: The ONBoost function is not available while
on bypass. The UPS will automatically switch to
normal output voltage mode when “bypass” is
selected. ONBoost operation is indicated by lighting
of the decimal point on the right side of the display.
Battery Backup
Mode
In a severe over- or under-voltage situation, the
microprocessor control circuits determine that AC
power is no longer in an appropriate voltage range.
The UPS rapidly switches to battery power to supply
continuous conditioned power.
While in backup mode, detector circuits monitor the
return of AC power. The UPS synchronizes with the
AC source frequency when utility power is available.
The AC source must be stable for 4-5 seconds before
the UPS will return to the AC source from battery. If
no further interruption occurs, the UPS switches to
AC power mode. The load equipment is supplied
continuously with conditioned power even when
running in battery backup mode.
If the battery becomes exhausted while maintaining
the load, a low battery warning is sounded, displayed
on the front panel, and transmitted via the
communications port a minimum of two minutes
prior to termination of battery backup. Once battery
backup terminates, the UPS output turns off. The
UPS monitors the line and provides output when
utility power is restored to normal operating range.
ON Series 3.3-5.0 kVA User Instruction Manual

Theory of Operation
Load Start-up
The UPS front panel display may initially show “c8”
or “c9” during the load power-up sequence due to
momentary current surges. The display returns to
“99” or less when the load is in range.
Fig. 2: UPS Front Panel Display
Output Overload
Protection
The UPS output is constantly monitored. If the
output is loaded to more than 105 percent of the UPS
watt rating, battery power to the load is not available.
The digital display for output overload is “c8.” If the
output load exceeds 125 percent, “c9” is displayed
and the output turns off completely after two
seconds. The digital display reads “c9” (or “c1” if the
input circuit breaker has opened).
To reset the UPS, turn the UPS front panel switch
“OFF.” Reduce the load or reset the breaker (if
necessary) and then turn the UPS front panel switch
“ON.” (See Input Protection on page 9 for more
information.)
For individual outputs that have circuit breakers,
excess current may open these breakers without
overloading the UPS. Reduce or redistribute the load
and reset the circuit breaker. (See figure 3 on page 9.)
Call ONEAC Technical Support for further
assistance. (See Technical Support on page 1.)
8
ON Series 3.3-5.0 kVA User Instruction Manual
Theory of Operation
Input Protection
A grossly overloaded UPS or shorted output, may
trip the rear panel input circuit breaker. The front
panel display reads “c9” or “c1” if the input circuit
breaker has opened. To reset the circuit breaker, set
the breaker to the “ON” position. (See figure 3.)
• 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
load. Add load to the output one device at a time.
Check the % load on 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. (See Technical
Support on page 1.)

Inspection and
Unpacking
Before shipment, this product was tested, inspected,
and found to be free of mechanical and electrical
defects. Upon receipt of your UPS, carefully
examine the exterior of the packing containers for
any sign of physical damage. Notify the carrier
immediately if damage is present.
Retain the packaging materials for reuse (refer to
Return Procedure on page 47) or dispose of the
materials properly.
Once unpacked, inspect the unit for any damage that
may have occurred in transit. If damage is evident,
contact ONEAC Technical Services immediately
(see Technical Support on page 1) for assistance.
Location
Before connecting equipment to the UPS, be sure
that the designated UPS location is easily accessible
for all connections: load to UPS, input power to
UPS, battery to UPS, and communications.
ON Series 3.3-5.0 kVA User Instruction Manual

Setup and Installation
Setup Precaution
CAUTION: Do not attach laser printers to the UPS.
A laser printer draws high power during use and
may overload the UPS.
ATTENTION: To reduce the risk of fire, connect
only to an agency-listed circuit breaker; 30 amps for
the ON3300 or 50 amps for the ON3305 and
ON5000. Maximum branch circuit overcurrent
protection must be in accordance with the NEC,
ANSI, NFPA70.
Environmental
Considerations
Ambient operation is 10,000 feet (3,000
meters) maximum elevation; 0 to 95% humidity,
non-condensing; and 32°F to 140°F
temperature(0°C to 40°C temperature).
Long Term
Storage
Improper long-term UPS storage may damage the
UPS battery and invalidate the battery warranty.
Unplugging a UPS from its AC power source for an
extended period of time results in reduced battery
charge. The system code may show a “c4” for 2 – 4
hours per battery cabinet after utility power is
restored.
To keep the batteries fully charged and to maximize
the life of the batteries, connect the UPS to a
properly wired input power source while it is in
storage.
If the UPS is stored without input power, connect it
to a power source for a minimum of 24 hours at least
once every 4 – 6 months.
ATTENTION: If the unit will be stored without input
power, be sure all battery breakers are in the “OFF”
position.
12
ON Series 3.3-5.0 kVA User Instruction Manual
Installing ON3300 and ON5000 Systems
ATTENTION: Be sure all battery breakers are in
the “ON” position during the periodic 24-hour
recharge procedure
If the storage temperature is greater than 86°F
(30°C), connect the UPS to a power source for 24
hours every 2 to 3 months.
The UPS must not be stored at temperatures below
+5°F (-15°C).
Ventilation
The ventilation requirement for the ON Series
3.3-5.0 kVA UPS is 4 inches (10 cm) minimum
clearance on the front and back and zero space on the
sides.

Connecting the Load
NOTE: It is acceptable to turn “ON” the rear panel
battery breaker prior to the AC breaker, however
turning on the AC breaker first is recommended to
reduce in-rush current stress on the battery breaker
and other components.
It is also recommended to verify all battery breakers
are “ON” every three months.
Connecting the
Load
1. Connect the load(s) to the UPS according to
equipment voltage requirements. (See figure 10
on page 19.)
2. Use the chassis grounding points, (see figure
10) to provide safety ground
connections for load devices powered
by the UPS.
NOTE: The UPS can deliver full rated output power
on either its 208/220-240V or its 115V outputs.
However, if the load is powered by the 115V circuits,
the maximum output current is limited to 15 amps
per duplex.
Positioning the
UPS
1. Position the UPS in its designated area,
ensuring all connections are maintained. Do not
risk accidental disconnection.
2. Using a 1/2” wrench, adjust the load levelers at
the bottom at each corner to stabilize and level
the UPS.

signal (factory default), remove the I/O PCB by
removing the screws and pulling the PCB out.
NOTE: Remove power before removing or inserting
the PCB.
Move the jumper on P3 to pins 1 and 2. Replace the
PCB.
32
ON Series 3.3-5.0 kVA User Instruction Manual
Standard Interface
Basic Interface
Specifications
The Basic interface primarily supports systems that
use signals indicating “AC Line Fail” and “Low
Battery” as status inputs to monitor software. These
indications are provided as RS232 level signals at
pins 5 and 8, again with pin 7 as signal ground. A
“condition not true” voltage level is at –5V (or less)
indicates AC Line or Battery Voltage is okay while a
“condition true” voltage level is at +5V (or higher)
indicates the AC Line has failed or the Battery
Voltage is low. An interface cable, such as ONEAC’s
CA-NTMERIDIAN, connects the UPS to systems
with software configured to respond to these outputs.
In Basic Interface Mode, the “Shutdown” signal at
pin 20 can turn off the UPS during battery backup
operation if the jumper on the Basic Interface PCB is
set for it to be enabled. Remove the PCB and move
the jumper on P3 to pins 2 and 3 to enable
“Shutdown”. Also check that P4 is set to 3-5 and 4-6
(factory default). When enabled, a positive voltage (3
to 24VDC with respect to pin 7) shuts down the UPS
Inverter to conserve the remaining battery charge. A
voltage at (or below) ground allows the Inverter to
run. See On Line or Inverter Remote Off Interface
Specifications on page 34 for further information.
Split Interface
Specifications
The UPS allows both the full-duplex
communications at pins 2 and 3 as well as the static
signaling at pins 5 and 8 to be enabled
simultaneously. Together, these can support both a
network server using the Advanced Interface as well
as a computer or other device using the Basic
Interface. ONEAC’s “Y-shaped” accessory cable
ONEPLUS‚is available for this purpose. By using
this cable, the Shutdown signal can be enabled by
moving the P3 jumper to pins 2 and 3 on the I/O
PCB.

A. Loads can be turned off. Turn the front panel
switch to the “OFF” position. Disconnect the
input power source by unplugging the line cord,
opening the branch breaker or UPS input AC
circuit breaker. Loosen the fasteners for the
Control Module and pull module out of its
connectors.
B. Loads cannot be turned off. Turn the Bypass
switch to the Bypass or ON position. Front Panel
Display should read “U6”. Loosen the fasteners
for the Control Module and pull module out of its
connectors. This will disconnect the UPS power
supplies.
1. Remove screws that secure the interface card to
the UPS rear panel.
2. Carefully remove the board. Handle with care at

3. Locate the “P3” I/O shutdown jumper.
4. Remove Jumper from Pins 1 and 2 (disabled).
5. Place jumper on Pins 2 and 3, enabling inverter
shutdown for Basic interface mode.
ATTENTION: Most computers do not control the
signal levels of voltage present on serial port
pins during the boot process. When starting a
computer while the UPS is operating on inverter,
the computer may inadvertently turn the UPS off if
inverter shutdown is enabled.

Battery Considerations
Battery
Considerations
The UPS must be adequately ventilated to prevent
system overheating and enhance battery life. The ON
Series 3300 and ON5000 UPS must be installed with
a minimum 4 inches (10 cm) clearance on the front
and back sides.
To ensure optimal performance and battery life,
ONEAC selects premium quality batteries and has
designed the UPS battery charger and test circuits to
match the characteristics of these batteries.
To preserve the performance and warranty of your
ON Series UPS, use only original equipment
replacement batteries. Using other than ONEAC
approved battery packs may result in reduced battery
performance or damage to the UPS.
The UPS uses sealed, leak-proof, lead-acid batteries
that do not emit corrosive gasses.
ATTENTION: The batteries in this UPS are
recyclable. Dispose of the batteries properly. See
Battery Disposal on page 42.
Battery
Maintenance
Customer maintenance of the ON Series UPS is
limited to battery pack replacement of the standard
ONXBC cabinet and in the control and power
modules. Contact ONEAC Technical Services (see
page 1, Technical Support) with any other service
needs.
Ordering New
Batteries
Replacement batteries may be ordered directly from
ONEAC (see Technical Support on page 1) or from
your local authorized representative or reseller.

Battery Considerations
Servicing
ONXBC Batteries
Contact the factory if your battery cabinet has a KS
or CR prefix in the model number. These models
have no user-serviceable or user-replaceable parts.
The ONXBC battery cabinet houses batteries in a
user accessible enclosure. Battery replacement is a
safe procedure that is safe from electrical hazards.
The UPS and the critical load may remain on-line
and operational during the procedure.
CAUTION: Battery back up is not available if all
battery strings are opened (disconnected).
The following precautions should be observed while
servicing battery systems:
CAUTION: To reduce the risk of electrical
shock:
• Remove any watches, rings, or other metal
objects.
• Use tools with insulated handles.
• Wear rubber gloves and boots.
• Do not lay tools or metal objects on top of
batteries.
• Disconnect charging source prior to
connecting or disconnecting battery terminals.
ONXBC Battery
Replacement
CAUTION: Each battery string consists of two
ONBP-517 battery packs. Replace both packs at the
same time. Premature battery failure or equipment
damage can occur if old and new batteries are
mixed. To order a replacement string, use ONEAC
part number ONBP-517X2
An ONXBC battery cabinet may have two or four
battery packs (1 or 2 strings).
If batteries are removed for any reason, take care to
mark them in their original pairs and replace them
together on the shelf they were originally on.
