3.2.2 UPS System Power Wiring Preparation

CAPACITORS INSIDE
REQUIRE 5 MINUTES

TO DISCHARGE

TO A SAFE LEVEL

AFTER ALL POWER

IS REMOVED.

SEE HANDBOOK

FOR INSTRUCTIONS.

The UPS system installation must meet the following guidelines:

• The system must be installed on a level floor suitable for computer or electronic equipment.

• The system must be installed in a temperature and humidity controlled indoor area free of conductive
contaminants.

Failure to follow guidelines may void your warranty.

The UPS equipment operating environment must meet the weight requirements shown in Table 3-1 and the
size requirements shown in Figure 3-1. Dimensions are in millimetres (inches).

WARNING

• HIGH TOUCH CURRENT EARTH CONNECTION ESSENTIAL BEFORE CONNECTING SUPPLY.
As a result of the connected loads high leakage current is possible. Connection of the earth
(ground) is required for proper product operation. Do not check UPS operation by removal of
the Earth (ground) connection.

• The UPS unit is not suitable for IT and corner-earthed power distribution systems.

WARNING

• RISK OF ELECTRIC SHOCK. This ups receives power from more than one source ­disconnection of the AC and the DC source is required to de - energise this unit before
servicing. After disconnecting the utility power and the DC power, authorised service
personnel should wait at least five minutes for capacitor bleedoff before attempting internal
access to the UPS module.

• Backfeed protection is an internally fitted option on this device. If this option, or an externally
fitted backfeed contactor are not installed. Select backfeed contactor are shown in Table 3-7
and Table 3-8.

• The below label should be applied on all primary power isolators installed remote from the
UPS area and on external access points.

• Refer to national and local electrical codes for acceptable external wiring practices.

• To allow for future kVA upgrades, consider installing a derated UPS using wiring and external overcurrent
protection breakers sized for a fully rated UPS.

• For external wiring, use 90°C copper wire. Wire sizes listed in Table 3-5 are for copper wiring only. If wire is
run in an ambient temperature greater than 30°C, higher temperature wire and/or larger size wire may be
necessary. Wire sizes are based on using the specified breakers.

• Material and labour for external wiring requirements are to be supplied by designated personnel.

• If installing an external maintenance bypass, all feeds to the UPS including the Rectifier Input Breaker (RIB)
(if installed) must have a service disconnect independent of the maintenance bypass power path. Most
maintenance bypass solutions provide UPS input feeds derived from but isolated from the maintenance
bypass power path. If the maintenance bypass solution being installed does not provide such functionality,
DO NOT use a single feeder breaker to supply both the UPS and the maintenance bypass.

3-15

• The bypass feed into this equipment uses four wires (three line conductors and neutral conductor), plus
grounding conductor (protective earthing conductor) . The rectifier feed into this equipment uses four wires
(three line conductors and neutral conductor), plus grounding conductor (protective earthing conductor). The
phases must be symmetrical about ground (from a Wye/Star source) for proper equipment operation.

• Parallel UPS input wiring size requirements and output wiring size requirements from the UPSs to the Tie
Cabinet are the sames as those for single systems.

• Install a proper three-pole overcurrent disconnect device before connecting to the UPS, the disconnect
device shall disconnect simultaneously all line conductors of the AC MAINS SUPPLY.

MBS (Maintenance bypass switch) is installed inside the UPS. When maintaining, open neutral switch and

•
MBS to isolation the UPS internal parts from the utility. Do not open neutral switch in any other cases
because the

neutral is required for UPS operation. For some VFI 60000-80000TAP 3/3 BX model without

internal neutral switch, external neutral switch shall be installed in site for maintenance.

• If a disconnect device interrupts the neutral conductor, it shall simultaneously interrupt all line conductors.

• When single-phase current exceeds 100A, switches of protective atmosphere should be equipped with
arc-control device.

• The UPS requires an input neutral connection. Ensure that an input neutral is connected prior to energising
the UPS. If a 4 pole Automatic Transfer Switch is installed upstream of the UPS it must work with a break
before make transition with a minimum transfer time of 50ms.

Figure 4-4 and Figure 4-5 show the location of the UPS power cable terminals.

Battery voltage is computed at 2 volts per cell. Rated battery current is computed at 2 volts per cell. The battery
wiring used between the battery and the UPS should not allow a voltage drop of more than 1% of nominal DC
voltage at rated battery current. If the conductors used for DC input from the battery cabinets to the UPS are
those provided by the UPS manufacturer, and the UPS and battery cabinets are manufactured by the same
supplier, then it is acceptable if they do not meet the noted minimum conductor sizes.

3.2.3 UPS System Interface Wiring Preparation

Control wiring for features and options should be connected at the customer interface terminal blocks located
inside the UPS.

WARNING

Do not directly connect contactor contacts to the mains related circuits. Reinforced insulation is
required before connecting to the mains.

Read and understand the following notes while planning and performing the installation:

• Interface wiring should be rated for 24V, 1A minimum.

• For interface wiring from 30V to 600V, the wire should be rated for 600V, 1A minimum.

• Because of the REPO and building alarm wiring route in the UPS cabinet, the wire should be rated for a
minimum of 300V.

• Use twisted-pair wires for each input and return or common.

• All interface wiring and conduit is to be supplied by the customer.

• When installing external interface wiring between a REPO or building alarm and the UPS interface terminals,
conduit must be installed between each device and the UPS cabinet.

• If using the power terminal wiring channel, keep interface wiring separate from power wiring or use shielded
wire.

• If using conduit, install the interface wiring in separate conduit from the power wiring.

• All building alarm inputs require an isolated normally-open contact or switch (rated at 24 Vdc, 20 mA
minimum) connected between the alarm input and common terminal. All control wiring and switch contacts
are customer-supplied.

4.3 External Battery Cabinet Installation

Before connecting the external battery, please read the notice and warning label on the battery cabinet.

• In the event of malfunction, the battery cabinet chassis or battery cabinet frames may become

live!

• Special care should be taken when working with the battery cabinet associated with the

equipment. Ensure the battery number is suited to the setting of the battery charging voltage

before installing the battery. When the battery cabinet is connected the overall voltage exceeds

nominal voltage. It is very important to ensure that the batteries are installed separately, in a

dedicated battery cabinet.

• Battery back-up time do not exceed one hour, if the battery setting shall be exceeded one hour,

consult to the professional personnel.

• The most common battery type used in UPS installations is the valve regulated battery. Valve
regulated cells are not sealed. The amount of gas given off is less than for flooded cells, but
when planning the battery installation, allowance must be made for adequate ventilation and
heat dissipation. Valve regulated cells are not completely maintenace- free. They must be kept
clean and their connections checked periodically to ensure they are tight, and that there is no
evidence of corrosion. It is inevitable that the batteries will lose charge during transportation and
storage; before attempting to carry out an autonomy test, ensure that the batteries are fully
charged as this may take several hours. Cell performance typically improves after a few
discharge/recharge cycles.

• The requirements of the EC directives are satisfied when battery cabinet are used with original
accessories. If alternative batteries are used, you must ensure that the applicable EC directives
are met and declare conformity.

WARNING

CAUTION

4-4

Connect the battery cabinet as follows:

1. Turn off the UPS.

NOTE

RJ-45 Controller Area Network (CAN) must be supplied by the customer.

To install wiring:

1. Verify the UPS system is turned off and all power sources are removed. See Chapter 6, “UPS Operating
Instructions", for shutdown instructions.

2. Installing Parallel system, see Figure 4-10 and Figure 4-12.

CAUTION

• Parallel system combined input and output cable length should be in accordance with the
following rule. It should be designed to ensure that wiring impedance from point of supply to
UPS input and from UPS output to load connection for each UPS module in a multi-module
system is equal, or within a tolerance of approximately ±10%. This is to ensure approximately
equal current sharing when in static bypass mode and restrain input/output high frequency loop
current of parallel system. Suggest that parallel system combined input and output cable length
no less than 10m, 5m for input and 5m for output.

Total length of 1A =2A=3A=4A

1B=2B=3B=4B

1C=2C=3C=4C

• If installing only two UPS modules (redundant), this requirement is no longer required as each
UPS is capable of supporting the full bypass requirement. However, this would preclude future
expansion.

• Ensure that each UPS static bypass is fed from a single common source, as is an external
bypass switch if installed. If each UPS is fed with a separate rectifier source, please consult for

advice on compatibility.

3. To locate the appropriate terminals and review the wiring and termination requirements, see
paragraph 3.2.3, Table 4-2, Figure 4-7, Figure 4-9, and Figure 4-10.

Operation

Chapter 5 Understanding UPS Operation

5.1 UPS System Overview

The VFI 20000-80000TAP 3/3 BE/BI/BX UPS is a continuous-duty, solid-state, three-phase, true online system
that provides conditioned and uninterruptible AC power to the UPS system's output and critical load.

The basic system consists of a rectifier, battery converter, inverter, monitoring/operation control panel, integrated
communication server, and digital signal processor (DSP) logic. Figure 5-1 shows the main elements of the UPS
system.

If utility power is interrupted or falls outside the parameters specified in Chapter 9, “Product Specifications,” the
UPS uses a backup battery supply to maintain power to the critical load for a specified period of time or until the
utility power returns. For extended power outages, the UPS allows you to either transfer to an alternative power
system (such as a generator) or shut down your critical load in an orderly manner.

The emergency bypass consists of a continuous static switch, and an optional backfeed protection contactor. The
backfeed protection contactor (if fitted) is located in series with the static switch. The static switch is armed and
ready during normal operation.

5-1

5.2 Single UPS

A single UPS operates independently to support an applied load from the inverter, providing conditioned and
uninterruptible AC power to the critical load from the output of the module. During an outage, the inverter
continues to operate, supporting power to the load from the battery supply. If the unit requires service, applied
loads are transferred to the internal bypass either automatically or manually. With the exception of an optional
external battery cabinet, no other cabinets or equipment are required for the single UPS to successfully support
its applied loads.

5.2.1 Modes

The VFI 20000-80000TAP 3/3 BE/BI/BX UPS supports a critical load in four different modes of operation:

• In Standard Normal mode, the critical load is supplied by the inverter, which derives its power from rectified

• In High-Efficiency (HE) mode, commercial AC power is supplied directly to the critical load through the

• In Bypass mode, the critical load is directly supported by utility power.

• In Battery mode, the battery provides DC power, which maintains inverter operation. The battery supports

The following paragraphs describe the differences in the UPS operating modes, using block diagrams to show
the power flow during each mode of operation.

utility AC power. In this mode, the battery charger also provides charging current for the battery, if needed,
Standard mode is the standard normal operating mode.

internal bypass and transfers automatically to Standard Normal mode (double-conversion on demand) if an
abnormal condition is detected.

the critical load.

5.2.2 Standard Normal Mode

During Standard Normal mode, power for the system is derived from a utility input source through the rectifier
input contactor. Three-phase AC input power is converted to DC using IGBT devices to produce a regulated DC
voltage to the inverter. When the battery contactor is closed the battery is charged directly from the regulated
rectifier output through a buck or boost DC converter, depending on the system voltage and the size of the
battery string attached to the unit.

Figure 5-2 shows the path of electrical power through the UPS system when the UPS is operating in Normal
mode.

The battery converter derives its input from the regulated DC output of the rectifier and provides either a
boosted or bucked regulated DC voltage charge current to the battery. The battery is always connected to the
UPS and ready to support the inverter should the utility input become unavailable.

The inverter produces a three-phase AC output to a customer's load without the use of a transformer. The
inverter derives regulated DC from the rectifier and uses IGBT devices and pulse-width modulation (PWM) to
produce a regulated and filtered AC output. The AC output of the inverter is delivered to the system output
through the output contactor.

If the utility AC power is interrupted or is out of specification, the UPS automatically switches to Battery mode
to support the critical load without interruption. When utility power returns, the UPS returns to Normal mode.

Figure 5-2. Path of Current Through the UPS in standard Normal Mode

If the UPS becomes overloaded or unavailable, the UPS switches to Bypass mode. The UPS automatically
returns to Normal mode when the overload condition is cleared and system operation is restored within
specified limits.

If the UPS suffers an internal failure, it switches automatically to Bypass mode and remains in that mode until
the failure is corrected and the UPS is back in service.

5.2.3 High-Efciency Mode

When the UPS is operating in HE mode, commercial AC power is supplied directly to the critical load through the
internal bypass with the power module in a standby state. If a commercial power brownout, blackout, overvoltage,
undervoltage, or out-of-tolerance frequency condition occurs the system forward transfers to normal mode
(double-conversion on demand) or battery mode. When the input line returns to normal operating range, the UPS
returns to HE operation. For charging batteries in HE mode, the UPS will revert to normal mode to charge the
batteries, then return to HE mode when charge cycle is complete.

HE mode, if selected, is a normal operating mode, and not an alarm condition. While the UPS is in this mode,
the NORMAL light on the front display will illuminate.

5.2.4 Bypass Mode

CAUTION

The critical load is not protected from voltage or frequency fluctuations or power outages while
the UPS is in Bypass mode.

The UPS automatically switches to Bypass mode if it detects an overload, load fault, or internal failure. The
UPS can also be transferred from Normal mode to Bypass mode manually. The bypass source supplies the
commercial AC power to the load directly. Figure 5-3 shows the path of electrical power through the UPS
system when operating in Bypass mode.

In Bypass mode, the output of the system is provided with three-phase AC power directly from the system
input. While in this mode, the output of the system is not protected from voltage or frequency fluctuations or
power outages from the source. Some power line filtering and spike protection is provided to the load but no
active power conditioning or battery support is available to the output of the system in the Bypass mode of
operation.

The internal bypass is comprised of a solid-state, silicon-controlled rectifier (SCR) continuous static switch, and
an optional backfeed protection contactor. The static switch is used instantaneously anytime the inverter is
unable to support the applied load. The continuous static switch is wired in series with the backfeed protection
contactor (if fitted), and together they are wired in parallel with the rectifier and inverter.

The static switch, being an electronically-controlled device, can be turned on immediately to pick up the load
from the inverter while inverter output contactor opens to isolate the inverter. The backfeed protection
contactor (if fitted) is normally closed, ready to support the static switch unless the bypass input source
becomes unavailable.

If the UPS transfers to Bypass mode from Normal mode due to any reason other than operator intervention,
the UPS automatically attempts to transfer back to Normal mode (up to three times within a ten minute
period). The fourth transfer locks the critical load to the bypass source and requires operator intervention to
transfer.

The UPS automatically transfers to Battery mode if a utility power outage occurs, or if the utility power does
not conform to specified parameters. In Battery mode, the battery provides emergency DC power that the
inverter converts to AC power.

Figure 5-4. Path of Current Through the UPS in standard Battery Mode

During a utility power failure, the rectifier no longer has an AC utility source from which to supply the DC
output voltage required to support the inverter. The input contactor opens and the battery instantaneously
supplies energy to the battery converter. The converter boosts the voltage so that the inverter can support the
customer's load without interruption. If bypass is common with the rectifier input, the backfeed protection
contactor also opens. The opening of the input and the optional backfeed protection contactors prevent
system voltages from bleeding backwards through the static switch and rectifier snubber components to the
utility source.

If the input power fails to return or is not within the acceptance windows required for normal operation, the
battery continues discharging until a DC voltage level is reached where the inverter output can no longer
support the connected loads. When this event occurs, the UPS issues another set of audible and visual alarms
indicating SHUTDOWN IMMINENT. Unless the rectifier has a valid AC input soon, the output can be supported
for only two minutes before the output of the system shuts down. If the bypass source is available, the UPS
transfers to bypass instead of shutting down.

If at any time during the battery discharge the input power becomes available again, the input and the backfeed
protection contactors close and the rectifier begins to supply DC current to the converter and inverter. At this
point, the unit returns to Normal mode. Depending on the total load and the duration of the battery discharge,
battery current limit alarms may be seen for a short time due to the current required to recharge the battery.

This screen shows any currently active alarms, notices, or commands. This screen shows any currently active
alarms, notices, or commands. For more information on using the events screen, see paragraph 6.2.6.

• System Event Horns – The system event horn beeps to alert an operator that an event needing attention is
taking place. The horn cycles at a half-second rate.

• System Event Indicators – The status indicators on the UPS control panel work with the event horn to let the
operator know when the UPS is operating in any mode other than normal. Only the Normal mode indicator is
illuminated during normal UPS system operation. The other indicators illuminate to indicate alarms or events.
When an alarm occurs, first check these indicators to see what type of event has taken place. For
descriptions of the status indicators, see paragraph 6.2.1.

• System Event Messages – When a system event occurs, a message appears on the LCD in the UPS status
area. This message is also written to the Events Log and may be added to the History Log. The messages are
divided into four categories: alarms, notices, status, and commands.

7.1 Mini-Slot Cards

The VFI 20000-80000TAP 3/3 BE/BI/BX UPS has two standard, factory-installed Mini-Slot communication bays.
See Figure 4-7 for bay locations. The UPS is compatible with the following Mini-Slot cards (see Figure 7-1):

• Network Management Card and Modbus/Jbus – provides remote monitoring through a Web browser

interface, e-mail, and a network management system (NMS) using SNMP and connects to a twisted-pair
Ethernet (10/100BaseT) network. The card also provides direct integration of UPS information (meters and
status) to a Building Management System (BMS) using the Modbus RTU protocol.

• Network Management Card – provides remote monitoring through a Web browser interface, e-mail, and a

network management system (NMS) using SNMP and connects to a twisted-pair Ethernet (10/100BaseT)
network.

• Management Card Contact and RS232 / Serial – two types of interfaces via a DB9 connector are available

with this card. Dry contact mode provides a simple way to transmit UPS information to an alarm system,
PLC, or computer system via dry relay contacts. The transmitted information is load powered, load on bypass,
load on battery, load on utility, battery fault, and low battery. RS232 mode provides an RS232 interface for
connection to a PC or to a UPS Control display unit. Jumpers are used to select the interface (contacts or
RS232).

LAN and telephone drops for use with Mini-Slot connectivity cards must be supplied by facility planners or the
customer.
