Trouble Is Coming Down The Power Line And You Must Be Prepared
Every operation in your business depends upon the instant,
around-the-clock availability of computers, servers and other
You Face Many Challenges In The
Pursuit Of Productivity
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.
Is There Really A Problem?
“My computer can ride right through a short blip
in the power—why do I need anything else?”
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.
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?”
You Need Efficiency... Without
Compromising Availability
“Budgets are tight, so I have to consider equipment costs
at all lifecycle phases — first cost, operation, and service.
How do I maximize efficiency and ensure reliability?”
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.
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.

power until back-up generators come on line.
The Liebert FS is engineered to support larger
Liebert UPS systems, including the Liebert Npower,
Liebert Series 610, Liebert NX and Liebert NXL
models. A single flywheel can be sized to support
UPS systems up to 225 kVA. Multiple flywheel
systems can operate in parallel to support larger
When the primary power source goes down, it’s
vital that the UPS has a reliable DC power source to
deliver energy to the critical loads. The Liebert FS
stores energy kinetically via flywheel inertia rather
than relying on chemical reactions of toxic lead and
sulfuric acid.

The Liebert FS stores energy kinetically. When
needed, inertia of the spinning mass is immediately
converted to power. The Liebert FS is a functional
replacement or supplement for a bank of chemical
batteries. Like batteries, it charges from the two
terminal UPS DC bus and returns up to 200 kW per
module whenever the bus voltage drops below a
programmable threshold.
The flywheel itself is a high-speed, carbon fiber
composite cylinder rotating in a vacuum. The
flywheel and rotating group is fully levitated and
centered by patented 5-point magnetic levitation
system that minimizes drag and eliminates
mechanical bearings maintenance and replacement.
Its synchronous reluctance motor-generator
minimizes idling losses and standby power
consumption. Originally designed for hybrid
vehicles, the levitation system is very robust and
responsive to any jarring.

the important next step.
Making Sure The Power Is Always There
When You Need It
Liebert’s range of power distribution equipment is
specially designed for high-availability applications.
It includes both distribution and switching systems
to provide reliable power to critical loads.

Rack Sized Power Distribution Cabinet
As your rack-based systems grow in
number, complexity and criticality—
so must your power distribution
system. To meet this challenge
Liebert has created a product
designed to optimize power
distribution at the rack level
with the “plug and play” flexibility
that today’s IT managers demand
from their systems.
The Liebert FDC distribution cabinet
extends the functionality of the PDU
by packaging 168 poles in a
stand-alone cabinet with a rack
foot print.
Any compartment can be serviced
or reconfigured without exposing
the wiring of the other three
The Standard Liebert FDC Unit Includes:
4 complete panelboards with main breaker (total 168 poles).
Front and rear access only.
Bottom cable exit.

Plug-in main panelboard breakers.
Liebert Remote Distribution Cabinet (RDC)
Power Distribution Systems
The Better Way To Wire High Density Facilities
The influx of client/server rack equipment is changing the content of data
centers. There are more devices than before—and they consume less power
than their predecessors. As a result, most power distribution units (PDUs)
run out of circuit breaker poles before they run out of rated capacity.
The Liebert Remote Distribution Cabinet (RDC) extends the functionality of
the PDU by packaging 168 poles (four complete 42-pole inline panelboards)
in a stand-alone cabinet.
Unlike standard Liebert Precision Power Centers (PPCs), the RDC has no
internal isolation transformer and requires 4-wire-plus-ground input from
a PPC or other transformer. By separating the PPC transformer from the
panelboard function, Liebert was able to create an extremely compact
package that fits the area of a standard 24” x 24” raised-floor tile.
The individual panelboards inside the Liebert Remote Distribution Cabinet
can receive power from different sources. This enables the RDC to provide
fault-tolerant, fully maintainable dual-bus power to nearby load equipment.
A dual-input RDC can be configured with two panelboards on each side
sharing common input terminals.
Other Features Of The Liebert RDC:
Unobstructed wiring access for easy of installation.
Complete isolation and maintainability.
Optional clear door insert panels enabling visual inspection
of the breakers without unlocking the cabinet.
Optional adjustable accent panels to make it easier to
compensate for breaker “creep”.
Single, dual or four-input configurations.
Optional current monitoring panel.

Power System Monitoring:
The Key To Continuous Operation
What You Don’t Know Can Hurt You.
A small problem in a critical facility can quickly
escalate into a disaster—knowing what is happening
with your power equipment, so you can keep that
protective “envelope” at peak operating efficiency,
is vital to system reliability.
Different People Need To Know
Different Things.
Liebert offers you more monitoring solutions than
anyone else because getting the right information
about your power equipment to the right people,
with the right level of urgency, is so important to
system availability.
We do this by allowing you to receive and use
information from your Liebert power equipment’s
microprocessor controls–no matter where it is located
or what communications protocol, operating platform
or building management system is being used.
In-band, out-of-band and web-based monitoring are
all available. From enterprise monitoring systems
to individual pieces of communications hardware,
you will know the exact problem so that you can
implement the right solution.
How Deep Does Your Monitoring
Need To Be?
Monitoring can range from a automated shutdown
software that provides basic operating information
from a single UPS unit, all the way to full-scale
monitoring and control of a critical facility including
trending and data analysis.
Your requirements will vary according to the specificity
of the information you need. You may require no more
than a local readout of a unit’s operating status. Or you
may need the ability to control its operation and
receive alarms.
These information requirements may also go beyond
basic monitoring and control. You may need the ability
to analyze performance data in order to pinpoint
trouble spots so that the same problems don’t
happen again and again.

Real uptime assurance. We have the proprietary
tools, industry knowledge and robust service
infrastructure to deliver real assurance that your
systems will be available when you need them.
Efficient downtime recovery. After all, if downtime
strikes, you need a partner that can get you back
online quickly with intelligent answers, rapid service
response and parts where and when you need them.
The Business Case For Regular Maintenance
60x Increase in MTBF
Regular OEM preventive maintenance increases the mean
time between failures (MTBF).
Increase in
Mean Time
For instance, the mean time between failures for a system
that receives 1 annual PM is 10 times greater than a system
that receives 0 PMs.
By contrast, a system that receives 4 annual PMs, as
opposed to 0 PMs, increases its duration between failures
by 51 times.
Number of Annual Preventive Maintenance Visits
Data is based on Mean Time Between Failure analysis for
three phase UPS systems (≥ 100kVA) with an Emerson
Network Power service agreement between 2002-2007.

Emerson Network Power’s Liebert Services Business
Your power equipment functions as a complete system. Shouldn’t your service provider?
Only Emerson Network Power has the expertise and experience to service your entire power

Power Availability
Availability depends
on the continuity of
power and the ability
of an uninterruptible
electrical supply to ride
through outages of
any duration.
Power Protection
Raw utility power
may be unsuitable for
sensitive technology
systems. In these
situations, surge
suppression and
power conditioning
can deliver the power
quality you need.
Power Conversion/Distribution
Converting and delivering power
throughout a large facility or a
small space is an important step
in protecting availability.
