3. Introduction

3.1 System and model description

This Online Series is an uninterruptible power supply incorporating
double-conversion technology. It provides perfect protection
specifically for computer equipment, communication systems to
computerized instruments.

Its true online double-conversion design eliminates all mains power
disturbances. A rectifier converts the alternating current from the
utility power to direct current. This direct current powers the inverte r.
On the basis of this DC voltage, the inverter generates a pure
sinusoidal AC voltage, which is constantly powering the loads.

Computers and Peripherals are thus powered entirely by the UPS. In
the event of power failure, the maintenance-free batteries power the
inverter.

This manual is applicable to the PowerWalker VFI 10000-20000 TP
3/1 models and PowerWalker VFI 10000T CP 3/1 model.

The tower 3-phase series UPS providing outstanding performance
and reliability, the UPS’s unique benefits include:

 Online UPS design with pure sine wave output.
 True online d ouble-conv ersion te chnolog y with hi gh power densit y,

utility frequency independence, and generator compatibility.

 Overall high efficiency > 93%, saving the operating cost.
 True three-phase power factor correction and high input power

factor (PF>0.99). Save the installation cost and reduce the
pollution back feed into upstream power system.

7

 High output power factor (0.9), to adapt more type load.
 Intelligent Battery Management technology that uses advanced

battery management to increase battery service life, optimize
recharge time.

 Selectable High Efficiency mode (ECO mode) or CVCF mode

operation.

 Combo input (single phase or three phase) auto detection
 Back-feed protection
 Start-on-battery capability for powering up the UPS even if utility

power is not available.

 Standard communication options: one RS-232 communication port,

one USB communi cation port.

 Optional connectivity cards with enhanced communication

capabilities.

 Remote shutdown control through the Remote Power-off (RPO)

port.

 For tower PowerWalker VF I 10000-20000 TP 3/1, Maintenances are

simplified by allowing the safe replacement of batteries without
powering down the UPS. But PowerWalker VFI 10000TCP 3/1 model
have no this function.

 N+X parallel redundancy to increase the reliability and flexibility.

The max p ar a llel numb er is 4.

 User-friendly LCD display and LED indicators.
 For tower PowerWalker VFI 10000-20000 TP 3/1, easily battery

exchange or extension and ava ilable to exten d the ba ckup time. But
PowerWalker VFI 10000TCP 3/1 model have no this function.

UPS, please refer to the appearance diagram.

2) For tower PowerWalker VFI 10000TCP 3/1 UPS, it is
recommended to select the UL1015 8AWG(10mm

2

) wire or other
insulated wire which complies with AWG Standard for the UPS
input and output wirings.

3) For PowerWalker VFI 20000TP 3/ 1 U PS, it is recommended to
select the UL1015 6AWG(25mm

2

) wire or other insulated wire
which complies with AW G Standa rd f or the UPS in put and out put
wirings.

Note: Do not use the wall receptacle as the input power source

for the UPS, as its rated current is less than the UPS’s
maximum input current. O therwise t he receptacle m ay be
burned and destroyed.

4) C onnect the input and output wires to the corresponding input
and output terminals according to the following diagram.

Note: you must make sure that the input and output wir es and

the input and output terminals are connected tightly.

5) The protective earth ground wire refers to the wire connection
between the equipment which consumes electri c eq uipment an d
the ground wire. The wire diameter of protective earth ground
wire should be at least as above mentioned for each model and
green wire or green wire with yellow ribbon wire is used.

6) A fter having completed the installation, make sure the wiring is
correct.

7) P lease install the output breaker between the output terminal
and the load, and the breaker should with leakage current
protective function if necessary.

17

8) To connect the load with the UPS, please turn off all the loads
first, then perform the connection and finally turn on the loads
one by one.

9) No matter the UPS is connected to the utility power or not, the
output of the UPS may have electricity. The parts inside the unit
may still have hazardous voltage after turning off the UPS. To
make the UPS have no output, power off the UPS, and then
disconnect the utility power supply.

10) Suggest charging the batteries for 8 hours before use. After
connection, turn the M1/M2/N input breaker (for PowerWalker
VFI 10000-20000TP 3/1), turn the input switch (for PowerWalker

6. Special Function

The series UPS has some special functions, which could satisfy some
special application of user. And the functions have own features,
please contact your local distributor for further information before
using the function.

6.1 HE Function

6.1.1 Brief Introduction of HE Function

If HE function is set to enable, after the UPS is turned on, the power
used by the load is directly supplied from the ut ility power via internal
filter while the utility power is in normal range, so the high efficiency
could be gained in HE mode. It is a lso called econo my mode. O nce the
mains is loss or abnormal, the UPS would transfer to Line mode or
Battery mode and the load is supplied continuously.

The great virtue is over all high ef ficiency >0.97 of UPS, to save powe r
for user.

But the disadvantage is 1) the load can not be protected as well as in
Line mode, for the load is directly supplied from the utility; 2) the
transfer time of UP S output from HE mode to Battery mode is about
10ms.

So the function is not suitable t o so me sens itive loads, and the region
where the utility power is unstable.

6.2 Converter Function

6.2.1 Brief introduction of Converter function

In converter mode, the UPS would free run with fixed output
frequency (50Hz or 60Hz). Once the mains is loss or abnormal, the
UPS would transfer to Battery mode and the load is supplied
continuously.

40

The great virtue is the output frequency is fixed, which is required by
some very sensitive loads.

But the load should be derated to 60% when running in converter
mode with single phase input, and there is no derating with three
phases input.

6.3 Parallel Function

6.3.1 Brief introduction of the redundancy

N+X is currently the most reliable power supply structure. N
represents the minimum UPS number that the total load needs, X
represents the redundant UPS number, i.e. the fault UPS number that
the system can handle simultaneously. When the X is larger, the
reliability of the powe r syste m i s higher. For occasions where reliabilit y
is highly depended on, N+X is the optimal mode.

As long as the UPS is equipped with parallel cables, up to 4 UPSs can
be connected in parallel to realize output power sharing and power
redundancy.

6.3.2 Parallel installation a nd operati o n
How to install a new parallel UPS system:

1) Before installing a new parallel UPS system, user need to prepare
the input and output wires, the output breaker, and the parallel
cable.

2) Users need to use a standard 25-pin communication cable, whic h
should have 25 cores, corresponding stitches and shield, as the
UPS parallel cable. The length of the paralle l cable is appropriate to
be less than 3m. And there is one standard parallel cable in the
accessor i e s of every UPS.

3) Remove the cover plate of the parallel port on the UPS, connect
each UPS one by one with the parallel cable, and re-screw the
Parallel port cover which is supplied in the accessories.

41

4) Strictly follow the chapter of 4, the wiring requirement o f single
UPS to perform the wiring of each UPS.

5) Connect the output wires of each UPS t o an output breaker panel.

6) Disconnect the Jumper on JP1 and JP2 of the terminal block f irst,
and connect each output breaker to a main output breaker and
then to the loads.

7) Each UPS need an independent battery pack.

8) Please refer to the wiring diagram in the following diagram.

9) The distance between th e UPSs in p arallel and the breaker pan el is
required to be less than 20 meters. The difference between the wires
of input and output of the UPSs is required to be less than 20%.

10) Do not switch on the output breaker of each UPS, switch on the
input breaker of the each UPS, the UPS should work in bypass with
output, observe their display to check if there are any warning or
fault information, measure the output voltage of each UPS
separately to check if the voltage difference between them is less
than 1V. If the difference is more than 1V, check the wiring.

11) Press the
all the UPSs would transfe r to the INV mode togethe r. Measure the
output voltage of each UPS separately to check if the voltage
difference between them is less than 0.5V. If the difference is more

How to join a new UPS to a parallel system:

1) First the parallel system must be installed one main maintenance

mechanical switch or static switch.

2) Regulate the output voltage of the new UPS separately: check if

the output voltage difference between the new UPS and the
parallel system is less than 0.5V.

3) Ensure the bypass of the parallel system is normal and the bypass

setting is “enable”, remove the cover plate of maintenance switch

8. Battery Maintenance, Replacement and
Disposal

8.1 Maintenance

■ This series UPS only requires minimal maintenance. The battery

used for standard models are value regulated sealed lead-acid
maintenance free battery. These models require minimal repairs.
The only requirement is to charge the UPS regularly in order to
maximize the expected life of the battery. When being connected
to the utility power, whether the UPS is turned on or not, the UPS
keeps charging the batteries and also offers the protective
function of overcharging and over-discharging.

■

The UPS should be ch arged once eve ry 4 t o 6 months if it has n ot

been used for a long time.

■

In the regions of hot climates, the battery should be charged and

discharged every 2 months. The standard charging time should
be at leas t 12 hours.

■

1. Hinweise zur Installation

1) Die USV muss an einem gut belüfteten, vor Wasser und
Schadgasen geschützten Ort installiert werden.

2) Die Belüftungsöffnungen an Vorder- und Rückseite dürfen nicht
blockiert werden. Es wird ein Abstand von mindestens 0,5 m
beidseitig empfohlen.

3) Wenn die USV in einer kalt en Um gebung aus ge packt wi rd, kan n e s
zur Kondensatbildung kommen. Die USV muss trocken sein bevor
sie installiert wird. Ansonsten besteht die Gefahr eines elektrischen
Schlags.

4) Sobald die Installation abgeschlossen ist, werden die
Seitenmontagehalterungen (verwen det in de r Schifff ahrt) befestigt,
um die Stabilität des USV-Gehäuses sicherzustellen. Falls
erforderlich, kann durch eine Verank e r ung der Mont agewinkel auf
dem Boden mit M8-Schrauben, eine zusätzliche Stabilität
hinzugefügt werden. Siehe Abb. 4-5. （nu r für PowerWalker VFI
10000-20000 TP 3/1）

Abb. 4-5 Zusätzliche Stabilität

2. Installa t ion

Die Installation und Verdrahtung sind durch autorisiertes

Fachpersonal nach den geltenden Bestimmungen unter Beachtung
der örtlichen Vorschriften durchzuführen.

Ziehen Sie aus Sicherheitsgründen bitte vor der Installation den

Netzstecker.

1) Öffnen Sie die Klemmenabdeckung auf der Rückseite der USV,
gemäß Schaltplan.

2) Es wird empfohlen, für Tower PowerWalker VFI 10000TCP 3/1
UPS, eine V er drahtung mit UL1015 Zulassung für AWG 8 (10mm

2

)
oder eine andere isolierte Verdrahtung zu wählen, die den AWG
Standard für den USV E i ngang und Ausgang erfü l lt.

3) E s w ir d emp fo hl e n, für PowerWalker VFI 20000TP 3/1 USV, eine
Verdrahtung mit UL1015 AWG 6 (25mm

2

) oder eine andere
isolierte Verdrahtung zu wählen, die den AWG Standard für den
USV Eingang und Ausgang erfüllt.

Hinweis: Verwenden Sie keine kommerzielle Steckdose für den

USV-Eingang, da der Nennstrom geringer ist als der
maximale Eingangsstrom der USV. Andernfalls kann die
Steckdose durchbrennen und zerstört werden.

4) verbinden Sie die Eingangs- und Ausgangsleitungen
entsprechend der Eingangs- und Ausgangsklemmen, gemäß
dem nachfolgenden Diagramm.

Hinweis: Sie müssen sicherstellen, dass die Eingangs- und

Ausgangsleitungen und die Eingangs- und
Ausgang s klemmen fes t verbunden s i nd.

5) Der Schutzerdungskabel bezieht sich auf die Drahtverbindung
zwischen dem Gerät, das elektrische Ausrüstung und
Erdungsdraht ve rbrau cht. Der Drahtdurchmesser der Schutzerde

wie oben erwähnt für jedes Modell und die Isolierung in der
Farbe Grün oder Grün mit gelben Streifen.

6) Nachdem die Installation abgeschlossen ist stellen Sie sicher,
dass die Verkabelun g k o rre kt ist.

7) Bitte installieren Sie den Ausgangsschutzschalter zwischen der
Ausgangsklemme und der Last und der Schalter sollte mit einer
Leckstromschutzfunktion ausgestattet sein, wenn nötig.

8) Um di e L as t m it d e r U SV zu verbinden, schalten Sie bitte zuerst
alle Lasten ab, führen die Verbindung durch und schalten dann
die Lasten nacheinander wieder an.

9) Egal ob die USV an das Stromnetz angeschlossen ist oder nicht,
kann USV-Ausgang trotzdem stromführend sein. Die Teile im
Inneren des Gerätes können noch gefährliche Spannungen
haben, nachdem die USV ausgeschaltet ist. Um die
Ausgangsleistung der USV auszuschalten, ziehen Sie den
Netzstecker.

10) Wir empfehlen, die Batterie vor dem ersten Gebrauch für 8
Stunden aufzuladen. Schalten Sie nach dem Verbindungsaufbau
die Eingangsschutzschalter M1/M2/N an (für PowerWalker VFI
10000-20000TP 3/1), drehen Sie den Eingangsschalter (für
PowerWalker VFI 10000TCP 3/1) in die "ON" Position, die USV
lädt die Batterie automatisch auf. Sie können die USV auch
verwenden, ohne die Batterien vorher aufzuladen, aber die
Backup-Zeit ist dann gerin ger als der Standardwert.

11) Falls es erforderlich ist die induktive Last, wie Monitor oder
Laserdrucker, an die USV anzuschließen, wird für die
Startleistung verwendet, um die K apazität der US V zu berechne n,
da der Stromverbrauch der Startleistung zu hoch ist.

4.3 Bedienungshinweise für den Anschluss einer
externen Batterie

1. Für PowerWalker VFI 10000-20000TP 3/1, Nominale DC-Spannung

des externen Akku-Pack ist 288VDC. Jeder Akku besteht aus 24
Teilen von 12V wartungsfreien Batterien in Serie. Für PowerWalker
VFI 10000TCP 3/1 Modell, die Nenngleichspannung des externen
Akkus ist 240VDC. Jeder Akku besteht aus 20 Stück von 12V
wartungsfreien Batterien in Serie, Um e ine längere B ackup-Zeit zu
erreichen ist es möglich, Multi-Akkupacks zu verbinden, aber das
Prinzip „gleiche Spannung, gleicher Typ“ sollte unbedingt
eingehalten werden.

2. Für PowerWalker VFI 10000-20000TP 3/1, wählen Sie eine
Verdrahtung mit UL1015 Zulassung für AWG 8 (10mm
(25mm

2

) oder eine andere isolierte Verdrahtung, welche die
AWG-Norm für die Verdrahtung der USV-Batterie erfüllt. Das
Verfahren zur Installation einer Batteriebank, sollte strikt
eingehalten werden. Andernfalls besteht die Gefahr eines
elektrischen Schlags.

1) Für Tower 3/1 Serie, falls die U SV über einen e xternen Akkupack

verfügt, trennen Sie zuerst den internen Akku
DC-Steckverbinder.

Abb. 4-7 Trennen des internen Akkupack DC-Steckverbinders

2) Ein DC-Trennschalter muss zwischen dem externen B atteriepack

und die USV angeschlossen werden. Die Kapazität des
Unterbrechers darf nicht kleiner sein, als in der allgemeinen
Spezifikation angegeben.

3) Stellen Sie den Unterbrecher des externen Akkupacks in die

“OFF” Position und schließen Sie den Akku an (24 Stück für
PowerWalker VFI 10000-20000TP 3/1, 20 Stück für
PowerWalker VFI 10000TCP 3/1) in Serie.

4) Für PowerWalker VFI 10000-20000TP 3/1, schließen Sie den

Akkupack an die Batterieterminals an. Für das PowerWalker VFI
10000TCP 3/1 Modell, schli eße n S ie de n ext ern en Akk upa ck an
den Batteriestecker an.

5) Schließen Sie den internen Akkupack DC-Steckverbinder wieder

an.

3. Versuche n Sie nicht, irgendwelche Lasten an die USV anzuschließen.
Sie sollten zuerst die Eingangsleitung in der richtigen Reihenfolge
verbinden. Stellen Sie dann den Schalter des Akkupacks auf die
„ON“ Position. Danach stellen Sie den Eingangsschutzschalter in die
„ON“ Position. Die USV beginnt die Akkus zu dem Zeitpunkt
aufzuladen.

5. Betrieb

5.1 Anzeige-Display

Die USV verfügt über eine Vier-Tasten-Grafik-LCD-Anzeige mit
