Chapter 1 Introduction
The Powerware®9390 uninterruptible power supply (UPS) is a true online, continuous-duty,
transformerless, double -conversion, solid-state, three -phase system, providing conditioned
and uninterruptible AC power to protect the customer’s load from all nine power failures.
The Powerware 9390 UPS is available as a single module or a multiple module parallel
system (see paragraph 1.1).
The Powerware online power protection system is used to prevent loss of valuable
electronic information, minimize equipment downtime, and minimize the adverse effect on
production equipment due to unexpected power problems.
The Powerware 9390 UPS continually monitors incoming electrical power and removes the
surges, spikes, sags, and other irregularities that are inherent in commercial utility power.
Working with a building’s electrical system, the UPS system supplies clean, consistent
power that sensitive electronic equipment requires for reliable operation. During
brownouts, blackouts, and other power interruptions, batteries provide emergency power
to safeguard operation.
The UPS system is housed in a single, free-standing cabinet with safety shields behind the
door for hazardous voltage protection. The cabinets matches the battery and distribution
cabinets in style and color and can be installed in line-up–and–match or standalone
configurations. Figure 1-1 shows the Powerware 9390 UPS (40–80 kVA).

For the UPS system to operate at peak efficiency, the installation site should meet the
environmental parameters outlined in this manual. If the UPS is to be operated at an
altitude higher than 1500m (5000 ft), contact your Powerware service representative for
important information about high altitude operation. The operating environment must
meet the weight, clearance, and environmental requirements specified in Drawing
164201535-2 on page A-3 and size requirements specified on Drawing 164201535-9
starting on page A-45.
The UPS cabinets use forced air cooling to regulate internal component temperature. Air
inlets are in the front of the cabinet and outlets are in the top. You must allow clearance in
front of and above each cabinet for proper air circulation.

Chapter 7 Understanding UPS Operation
7.1 Looking Inside the UPS System
The Powerware 9390 UPS is a continuous-duty, solid-state, transformerless (at 208 and
480 Vac), three-phase, true online system that provide conditioned and uninterruptible AC
power to the UPS systems output. The UPS supports process control, data processing,
telecommunications/PBX, research, and non-patient medical equipment. The Powerware
9390 UPS maintains power to the critical loads during commercial electrical power
brownout, blackout, overvoltage, undervoltage, and out-of-tolerance frequency conditions.
The basic system consists of a rectifier, battery converter, inverter, monitoring/operation
control panel, integrated communication server, and digital signal processor (DSP) logic.
In this manual, the power required by your equipment is called the critical load.TheUPS
supplies the critical load with conditioned power that is synchronized with your utility
power. Figure 7-1 shows the main elements of the UPS.

Understanding UPS Operation
If utility power is interrupted or falls outside the parameters specified in Chapter 15,
“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-duty static switch and backfeed protection
contactor K5. The backfeed protection contactor is located in series with the static switch.
For manual transfers to bypass, the static switch is also used. The static switch is armed and
ready during both types of transfers.
The operation of the UPS system is described in greater detail in the following paragraphs.
TheUPSmodulemaybeconfiguredforstandalone,singlemodule,ReverseTransfer(RT)
operation or multiple module, parallel redundant and/or parallel capacity operation (see
paragraphs 7.2 and 7.3).
7.2 Single Module Reverse Transfer (RT)
Asinglemoduleoperatesindependentlytosupportanappliedloadfromtheinverter,
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, continuous-duty static switch either automatically or manually. With
the exception of a battery cabinet, no other cabinets or equipment are required for the
single module to successfully support its applied loads.
7.2.1 Single Module RT Modes
The Powerware 9390 UPS supports a critical load in three different modes of operation.
The UPS can automatically use all three modes, as required. The standard operation
modes are:
쑺 In Normal mode, the critical load is supplied by the inverter, which derives its power
from rectified utility AC power. In this mode, the battery charger also provides charging
current for the battery, if needed.
쑺 In Battery mode, the battery provides DC power, which maintains inverter operation.
The battery supports the critical load.
쑺 In Bypass mode, the critical load is directly supported by utility power.
7-2
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
Understanding UPS Operation
The UPS continually monitors itself and the incoming utility power, and automatically
switches between these modes as required, without operator intervention. The
sophisticated detection and switching logic inside the UPS ensures that operating mode
changes are automatic and transparent to the critical load, while internal monitoring
systems indicate the current mode of operation. The UPS switches operating modes in
response to these system events:
쑺 A command is an intervention that is externally initiated by an operator or by some site
action. A command causes the UPS to switch operating modes; it usually does not
require any further action.
쑺 A notice is a minor system event that may or may not require attention.
쑺 An alarm is a system event that requires immediate operator intervention.
System events, alarm horns, and indicator lights are described in Chapter 12, “Responding
to System Events.”
The following paragraphs describe the differences in the three UPS operating modes, using
block diagrams to show the power flow during each mode of operation.

Figure 7-2. Path of Current Through the UPS in Normal Mode – RT
During normal UPS operation, power for the system is derived from a utility input source
through the rectifier input contactor K1. The front panel displays “Normal,” indicating the
incoming power is within voltage and frequency acceptance windows. Three-phase AC
input power is converted to DC using IGBT devices to produce a regulated DC voltage to
the inverter. The battery is charged directly from the regulated rectifier output through a
buck or boost DC converter, depending on whether the system is 208V or 480V and the
size of the battery string attached to the unit.
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 UPS monitors the battery charge condition and reports the status on the control panel.
The battery is always connected to the UPS and ready to support the inverter should the
utility input become unavailable.
7-4
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
Understanding UPS Operation
The neutral from the system input is connected to the neutral regulator in the DC
capacitors. The output neutral of the system is connected with the required neutral
supplied at the utility bypass input and should never be bonded to ground at the module’s
output.
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 K3.
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.
IftheUPSbecomesoverloadedorunavailable,theUPSswitchestoBypassmode.TheUPS
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.

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.
7-6
The internal bypass is comprised of a solid-state, silicon-controlled rectifier (SCR) static
switch (SSW) and a backfeed protection contactor K5. The static switch is rated as a
continuous-duty device that is used anytime the inverter is unable to support the applied
load. The static switch is wired in series with the backfeed protection contactor, 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 the inverter output contactor K3 opens to isolates the inverter. The
backfeed protection contactor is normally always closed, ready to support the static switch
unless the bypass input source becomes unavailable.
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
Understanding UPS Operation
During an outage, the UPS prohibits transfers to bypass and provides upstream protection.
The backfeed protection contactor is opened, preventing system output voltage from
bleeding across the static switch snubber components to the bypass input source.
To ensure the load remains energized, the UPS automatically transfers the output to the
internal bypass when one of these abnormal conditions occur: the output of the system
exceeds acceptable voltage and frequency tolerances, the system is overloaded, or the
inverter fails. The transfer is initiated by turning on the static switch and opening the
output contactor K3, also called a Make-Before-Break transfer. The transfer occurs in less
than 4 mS (quarter cycle) to ensure that the output load is not interrupted. The static
switch remains on until either the inverter is able to support the system output or the unit
is placed into a maintenance position where repairs can be made.
If the UPS initiates its own transfer to bypass for any reason other than operator
intervention, the UPS attempts to restart the inverter (if not running already) and attempts
a transfer back online to support the output of the system. Three attempts are made
within ten minutes to return the inverter online automatically before the UPS locks out any
further attempts. After three attempts, the UPS remains in bypass and an alarm condition
is enunciated. The UPS can also be transferred to bypass using the front panel controls.
Bypass mode is a normal operating mode, not an alarm condition. However, if the UPS is
unable to return to Normal mode following an automatic transfer to Bypass mode, an
alarm condition is recorded.

7.2.4 Battery Mode – RT
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.

During a utility power failure, the rectifier no longer has an AC utility source from which to
supply the DC output current required to support the inverter. The input contactor K1
opens and the battery instantaneously supplies energy the battery converter. The converter
either bucks or boosts the voltage so that the inverter can support the customer’s load
without interruption. If bypass is common with the rectifier input, the feed back protection
contactor K5 also opens. The opening of contactors K1 and K5 prevent system voltages
from bleeding backwards through the static switch and rectifier snubber components and
re-entering the input source.
7-8
While in Battery mode, the UPS sounds an audible horn, illuminates a visual indicator lamp
on the front panel (System Normal, On Battery), and creates an entry into the alarm event
history. As the battery discharges, the converter and inverter constantly make minute
adjustments to maintain a steady output. The UPS remains in this operating mode until the
input power to the rectifier is again within the specified voltage or frequency acceptance
windows.
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
Understanding UPS Operation
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,
contactors K1 and K5 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.
The system’s total operating time on battery depends on many factors. Some factors that
affect battery support times are battery type and capacity, number of parallel strings,
environmental temperatures, age of the battery, and fluctuations in load demand during
the discharge. The greater the load, the less support time the battery has. Decreasing the
load generally increases the battery support time.
7.3 Multiple Module Parallel System
Parallel operation extends the normal operation of Powerware 9390 UPS units by offering
increased capacity and/or redundant capability. The parallel system continues to maintain
power to the critical loads during commercial electrical power brownout, blackout,
overvoltage, undervoltage, and out-of-tolerance frequency conditions. See Drawing
164201535-4, sheets 3 of 5, 4 of 5, and 5 of 5 in Appendix A, for a detailed relationship of
the parallel system.
The output of the system is normally supplied by several uninterruptible power modules.
Multiple UPMs are connected with their outputs in parallel (tied together) to provide a
load level greater than the rating of one UPM and/or for redundancy. The paralleled UPMs
supply the output load with protected power as long as the load does not exceed the
combined rating of the paralleled UPMs.
The power system is redundant as long as one of the UPMs can be disconnected from the
output bus and the remaining UPMs can continue to supply power to the load without
exceeding their ratings.
When the load is being supplied by the UPMs, the system output bus is continuously
monitored for an overvoltage o r undervoltage condition. If an out of limits condition is
detected, the paralleled UPMs transfer the load to b ypass using the UPM static switches.
Communication is required between the UPMs for system metering and mode control.
System level communication and control are accomplished using a Computer Area
Network. A single building alarm in each UPM, connected to the other UPMs in parallel,
and tied to the bypass contactor auxiliary contacts in each UPM are used for a secondary
communication path. This arrangement ensures bypass control even if the CAN bus is lost.
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
7-9
Understanding UPS Operation
Up to four units can be paralleled for redundancy or capacity without any additional
cabinets.
The system is paralleled for redundancy (1 + 1) in a system where two UPMs are paralleled
together and the load is less than the supporting capability of one of the UPMs. The system
is paralleled for capacity (2 + 0) if both UPMs in a system are required to support the load.
A parallel capacity system can also be redundant (2 + 1), as long as there is always one or
more UPMs online than required to support the load.
7.3.1 Multiple Module Parallel System Modes
Similar to the single module system, the Powerware 9390 UPS parallel system supports a
critical load in three different modes of operation. The standard operation modes are:
쑺 In Normal mode, the paralleled UPMs supply the critical load with clean, filtered power.
Each UPM battery charger also provides charging current for the battery if needed.
쑺 In Battery mode, the battery provides DC power, which maintains UPM operation. The
UPM batteries supports the critical load.
쑺 In Bypass mode, the c ritical load is directly supported by utility power throu gh the
continuous-duty static bypass switch in each UPM.
The UPMs continually monitor themselves and the incoming utility power, and
automatically switch between these modes as required, without operator intervention,
except when manually switching to Bypass mode. The sophisticated detection and
switching logic inside the UPMs ensures that operating mode changes are automatic and
transparent to the critical load, while internal monitoring systems indicate the current
mode of operation. The UPMs switch operating modes in response to these system events:
쑺 A command is an intervention that is externally initiated by an operator or by some site
action. A command causes the UPMs to switch operating modes; it usually does not
require any further.
쑺 A notice is a minor system event that may or may not require attention.
쑺 An alarm is a system event that requires immediate intervention.
System events, alarm horns, and indicator lights are described in Chapter 12, “Responding
to System Events.”
To assist in developing an understanding of the parallel systems modes of operation,
review and understand thoroughly the single module modes of operation

The following paragraphs describe the differences in the three parallel system operating
modes, using block diagrams to show the power flow during each mode of operation.
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
7.3.2 Normal Mode – Parallel
In Normal mode, utility AC power is supplied to the UPMs. Each UPM then conditions the
incoming AC power and provides clean, regulated AC power to either a module tie cabinet
or distribution panel for parallel systems up to four modules The applied load is equally
shared among the available UPMs in the system.

in Normal mode.

7.3.3 Bypass Mode – Parallel
In Bypass mode, the output of the system is provided with three-phase AC power directly
from the bypass input. While in this mode, the output of the system is not protected from
fluctuations, spikes, or power outages from the source. No power filtering, conditioning, or
battery support is available to the output of the system in the Bypass mode of operation.
The parallel system automatically switches to Bypass mode if it detects a UPM overload,
UPMs unavailable, load fault, or internal failure.

In a parallel redundant or capacity type system, each module operates similar to a single
module, but in parallel with each other. The bypass source for the load is derived from the
bypass input of one, two, three, or four modules, depending on the system configuration
through the their internal continuous-duty static switches. If a module is taken offline, the
othermodulesremainsonlinetosupporttheload.Ifthemoremodulesthancansupport

Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
Understanding UPS Operation
The parallel system can be transferred from Normal mode to Bypass mode manually.
However, the parallel system automatically switches to Bypass mode whenever the UPMs
can no longer supply the critical load. If the parallel system transfers to Bypass mode from
Normal mode due to an output voltage deviation, the parallel system automatically
attempts to return to Normal mode (up to three times within a 10-minute period). After
three transfer attempts or an overload, the system locks the critical load to the bypass
source and requires operator intervention to transfer.
Bypass mode is a normal operating mode, not an alarm condition. However, if the parallel
system is unable to return to Normal mode following an automatic transfer to Bypass
mode, an alarm condition is recorded.

In the Parallel Redundant (N + 1) arrangement, the continuous-duty static switch in each
module operates to support the applied loads on bypass. If both units are in NORMAL and
one unit trips offline, the remaining unit does not go to bypass as long as it has the
capacity to support the load.
In the Parallel Capacity (N + 0) arrangement, if one unit trips offline and goes to BYPASS,
the remaining units also go to BYPASS.

While in Battery mode, the UPMs sounds an audible horn, illuminates a visual indicator
lamp on the front panel (System Normal, On Battery), and creates an entry into the alarm
event history. As the battery discharges, the boost converter and inverter constantly make
minute adjustments maintaining a steady output. The UPMs remains in this operating mode
until the input power to the rectifier is again within the specified voltage or frequency
acceptance windows.
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
Understanding UPS Operation
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 shared loads. When this event occurs
on each UPM, UPMs that are about to be shut down issue another set of audible and visual
alarms that indicate a two-minute SHUTDOWN IMMINENT warning. Unless the system has
a valid AC input soon, redundant UPMs b egin shutting down until there are no longer
enough UPMs online to support the connected load. When this event occurs, the system
shutsdown.Ifthebypasssourceisavailable,thesystemtransferstobypassinsteadof

If at any time during the battery discharge the input power becomes available again, the
rectifier begins to supply DC current to the inverter. At this point, the unit returns to
Normal mode. If at any time during the battery discharge the AC input power becomes
available again, each rectifier turns on, assumes the inverter load from the batteries, and
begins recharging the batteries. Depending on the total load and the duration of the
battery discharge, battery and rectifier input current limit alarms may be seen for a short
time due to the current required to recharge the batteries.
7.4 Functional Description
The UPS is a true online double-conversion unit with a transformerless power train. A
high-frequency active rectifier powers a high-frequency three-phase inverter. The bypass
circuit uses a solid-state continuous-duty static switch. The UPS operates from battery
strings from 192 cells (384V) to 240 cells (480V).
7.4.1 Input Rectifier
The rectifier is a three-phase, high-frequency PWM, IGBT-based power conversion stage
that provides input power factor correction and low input current harmonic distortion. The
rectifier maintains a DC level that is optimized for maximum inverter efficiency. A
precharge system charges the energy storage elements in the power train prior to
energizing the rectifier.
7.4.2 Inverter
The inverter is a three-phase, high-frequency PWM, IGBT-based power conversion stage
that continuously supplies the critical load with high-quality AC power. The IGBTs are
modulated to maintain the highest efficiency.
7.4.3 Battery Charger and Advanced Battery Management
The charger is a high-frequency, IGBT-based power conversion stage. The UPS u ses
Advanced Battery Management (ABM) technology, which essentially isolates the battery
from the electrical environment, except for periodic charging or reserve mode operation,
extending its life.
ABM extends battery life by keeping the batteries charged and performing periodic battery
testing.
Powerware®9390 UPS (40–80 kVA) Installation and Operation Manual S 164201535 Rev C
7-15
Understanding UPS Operation
An ABM charging cycle starts with the charger driving the battery voltage, at maximum
current limit, to a battery charge level of 2.34 volts/cell. The time it takes for the voltage to
reach to the battery charge level is saved as the battery charge time. If the battery charge
time exceeds 100 hours, an alarm is annunciated.
As soon as a battery charge level of 2.34 volts/cell is reached, the battery is charged at a
float level of 2.31 volts/cell for 48 hours (battery float time) plus 150% of battery charge
time. Twenty-four hours into the float period, a series of battery tests are performed to
check the battery health. The float level charge continues after a successful test.
At initial startup, the battery run time on the front panel display indicates two minutes.
After the 24-hour float charging period and battery testing, the actual battery run time is
determined and the actual battery run time is displayed.
After the float period is completed, the charger is disconnected and the batteries are
allowed to rest for 672 hours (28 days) maximum rest time. If the battery voltage falls
below the opportunity charge level of 2.1 volts/cell during the first 240 hours of the rest
period, an alarm is annunciated.
An ABM charge cycle is initiated whenever one of these four conditions occurs since the
last charge cycle:
쑺 The batteries have rested over the maximum rest time of 672 hours.
쑺 Accumulated discharge time is over a maximum battery discharge time of 20 seconds.
쑺 Battery voltage is under the opportunity charge level of 2.1 volts/cell and the unit h as
been in rest mode for longer than 240 hours.
쑺 An XCP command Initiate Battery Test is received.
7.4.4 Bypass
The bypass has a continuous-duty fully-rated SCR switch in the bypass circuit and a
contactor in the inverter leg. In Normal mode, the contactor connects the inverter to the
output. A backfeed contactor is also provided.
7.4.5 Batteries
The UPS operates from battery strings from 192 cells (384V nominal) to 240 cells
(480V nominal).
