Every operation in your business depends upon the instant, around-the-
clock availability of computers, servers and other electronic systems. If they
aren’t working, neither is your company.
Unfortunately, every piece of this equipment your company possesses is
subject to the whims of the electricity that powers it.
The first step in taking control of this situation is to understand the threats
to your system reliability—and exactly what you can do about them.
You Face Many Challenges In The
Pursuit Of Productivity
Is There Really A Problem?
“My computer can ride right through a short blip in the
power—why do I need anything else?”
There Are No Simple Solutions
“I have people telling me all I need to do is plug each
workstation into a small UPS from the computer store .
That’s good enough, isn’t it?”
Different Needs Require Different Power
Protection Configurations
“Should I have a small UPS for each workstation or
have everything on one large system . Which is best
for my facility?”
A Lot Can Happen Between Your UPS And
The Equipment It Is Protecting
“We have dozens of pieces of networking equipment. How
can I make sure that each one is getting exactly the power
it needs?”
Every Wire Carries The Potential
For Trouble
“An electrical surge came in through an outside phone line
and knocked out our entire communications system. Is this
going to happen again?”
A Single Source Of Power Simply May
Not Be Enough
“Adding a second power feed would certainly enhance our
availability picture—but who can we talk to about getting
it done right?”
4
Trouble Is Coming Down The Power Line And You Must Be Prepared

But There Are Real Solutions
You Need Protection From All Power Problems
An outage is just the problem you can see. There are many other more frequent power fluctuations—surges, spikes, sags—
that you don’t see. These are the conditions that cause the “unexplained” lock-ups and other potentially damaging results.
“Out-Of-The-Box” Can Put You Out Of Business
Buying a simple off-line UPS down at the computer store may be a good solution for your home PC, but it just doesn’t make
sense when your business and productivity are on the line. Protecting critical network and computing systems requires the
expertise of someone who understands all the risks you face from poor power quality.
Centralized Vs. Distributed UPS Protection
Liebert has the breadth of products that allows you to implement either a centralized or a one-on-one distributed power
protection strategy depending on your requirements. Whatever configuration you choose, you can count on Liebert to
make it the best it can be. Benefits, such as increased system security, more efficient maintenance and improved reliability,
may make a centralized strategy a better choice for larger operations.
Proper Power Depends On Proper Distribution
In network applications, there may be hundreds of different loads with various voltage requirements, a mix of AC and DC
power, plus any number of other electrical specifications. This calls for a distribution system that is designed to maintain the
highest levels of reliability and quality between the source of conditioned power and the protected equipment.
Power Conditioning And Surge Protection Throughout The Facility
Power conditioning and surge suppression systems are key to maintaining power quality in critical facilities. Raw utility
power is often far too “dirty” for sensitive systems, resulting in lost or garbled data, unexpected software glitches or
shutdowns, even hardware damage. The IEEE recommended practice is to install transient voltage surge suppression (TVSS)
protection on every electrical conductor that penetrates a facility shell, including power lines, telephone and other
communications links.
Maximum Reliability Demands Dual Power Sources
If your needs require the highest level of system availability, Liebert has the knowledge and products to implement a dual-
power strategy throughout your enterprise. UPS, transfer switching, power distribution and other equipment are all
brought together to create the ultimate in reliability.

operations centers, 911 response
emergency dispatch, police and fire
facilities, medical facilities, public
works operations and more.
Desktop/Peripherals—Home and
small office computers, modems,
network components and other
electronic equipment that is vital
to business operations.
Point-of-Sale—Today’s cash
registers and store-level computer
networks not only handle sales
transactions, they also collect
and transmit vital customer and
inventory data required to make
informed supply chain decisions.

Liebert GXT2 6 & 10 kVA UPS systems provide true
on-line protection in the smallest cabinets in their
capacity range. The UPS systems offer internal
batteries, unlimited extended external batteries, and
internal bypass capability, resulting in continuous
uptime for the connected equipment. This makes
the UPS an ideal fit in applications where the
power requirements are demanding—but rack
space is limited.
Application versatility is achieved through the use of
a dual inverter design capable of providing
simultaneous output voltages of 240/120, 208/120,
230/115, 220/110, or 200/100 VAC. The input is
power factor corrected to approximately .98,
enabling the UPS to power a wide variety of
equipment with different voltages.
For installation flexibility, you may choose from
several different wiring configurations made possible
by the use of removable power distribution boxes
that simply plug into the rear of the UPS. Options
include hardwired or receptacle connections, as well
as maintenance bypass capabilities.

The Liebert Nfinity power system is a scalable 4
to 16 kVA or 12 to 20 kVA UPS designed with N+x
parallel redundancy to provide a fault-tolerant
network of power protection.
The modular design of the Liebert Nfinity power
system was devised to provide easy scalability to
users as their power demands grow. Configurations
can be cost-effectively upgraded without re-
investing in a new system or installation.
The Liebert Nfinity is a true on-line, double-
conversion UPS that provides 100% power
conditioning, zero transfer time to battery, no
change in output voltage and better transient
suppression than line-interactive units.
Its unique frame design houses all of the modular
system components, including 4 kVA power
modules, battery modules and system control
modules. By simply installing additional power or
battery modules, you can expand your current
system, extend backup runtime or add redundancy.
nIntelligent power modules provide protection
from all power aberrations, and a patent pending
electrical current-sharing technology provides
equal distribution of power among all modules.
nThe IntelliBattery™modules utilize multiple
sensors to continuously monitor battery voltage,
current and temperature to determine and
predict performance.
nThe IntelliControl™module works with the user
interface to provide vital information about the
condition of the power and battery modules.
