Modes of Operation
The Nfinity UPS is designed to operate as a true
on-line system in the following modes:
Recharge Mode
When AC mains is restored, the unit will then
automatically recharge the battery modules until
they are fully charged.
Normal Mode
The Power Module’s power factor correction
circuitry derives power from the mains AC
source and supplies regulated DC power to the
inverter. The module’s inverter regenerates
precise AC power to supply the connected
equipment. The battery charger maintains a
float-charge on the battery.
Bypass Mode
The bypass provides an alternate path for power
to the connected equipment and operates in the
following manner:
Automatic
Back-Up Mode
In the event of an internal fault or should the
inverter overload capacity be exceeded, the
UPS performs an automatic transfer of the
connected equipment from the inverter to
the bypass source.
When AC mains fails, the connected equipment
is supplied power by the inverter, which obtains
energy from the battery modules.
The
connected load will not be interrupted during the
failure or restoration of the AC mains source.
Manual
Auto Restart Mode
Should the UPS need to be taken out of
service for limited maintenance or repair,
manual activation of the bypass will cause
an immediate transfer of the equipment from
the inverter to the bypass source.
After a power outage and complete battery
discharge, once the AC mains is restored, the
UPS will automatically restart and resume
supplying power to the connected equipment.
This feature is enabled at the factory, but can be
disabled by the user.
The user can also
program two auto restart delay settings:
1. Battery capacity level (%)
2. Countdown timer

User Interface Module
System Control Module
The System Control Module is the
communicative backbone of the UPS. It
gathers input from all modules and processes
the data to control the operation of the
system – including monitoring the condition of
each module. An optional second System
Control Module can be installed to provide full
system
redundancy
(operation
and
communication), in the unlikely event a
Control Module should fail.
Under normal operation, the Status LED
(green) will blink and the Fault LED (amber)
will be off. For any condition other than this,
check the Troubleshooting section of this
manual.

Power Module
Battery Module
The Power Module maintains the condition of
power in the Nfinity UPS. Each module is an
independent 4 kVA unit, consisting of a power
factor corrected rectifier, battery charger, and
inverter, with associated monitoring and controlcircuitry. The modules are paralleled to provide
greater capacity and/or redundancy. Modules
may be added or replaced on-line with no
interruption or danger to the connected
equipment.
The Battery Modules provide back-up power in
the event of input mains failure. Each module
contains a quantity of ten individual 12-volt valve
regulated (VRLA) battery blocks with associated
monitoring and controls to isolate the battery
module in the event of a battery failure. The
modules are paralleled to provide greater backup time and/or redundancy. Modules may be
added or replaced on-line with no interruption or
danger to the connected equipment.

Configuring the Bypass Voltage (TB2)
(Transformer Models Only)
The UPS voltage is factory set to 230V / 240V.
Should the user have a utility supply of 220 V,
the bypass voltage jumper will have to be
changed to ensure correct output voltage during
bypass mode.
Notes:
If an output transformer is fitted and the start-up is on bypass
the UPS has a 3-cycle inrush current that is 6 times the rated
output current. This must be taken into account when
selecting the overload protection device at the AC input
supply distribution point. To avoid random tripping on start
up, it is recommended that the AC input supply be protected
with a circuit breaker capable of withstanding this initial
inrush. (An MCB rated to curve ‘D’ or specified as being
‘Type 4’ (British standard) is suitable for this purpose).
This UPS is fitted with EMI suppression filters. Earth
leakage current is less than 40mA. Transient and steady
state earth leakage currents may occur when starting the
equipment. This should be taken into account when
selecting instantaneous RCCB or RCCD devices, as the
earth leakage currents of both the UPS and load will be
carried by these.
An overcurrent protection device (circuit breaker or fused
disconnect switch) must be installed for the AC output.
This UPS does not incorporate automatic back feed
protection.

Module Replacement
Follow the instructions below when replacing a
control, battery, or power module, or when
adding modules to the system.
To order
additional modules, contact your Liebert
representative.
Removing Modules
1. Remove bezel cover of appropriate module.
When replacing a Power or Battery Module,
verify the faulty module by confirming the
amber LED is lit.
2. If removing a Control or Power Module with
no redundant modules, switch UPS to
manual bypass. Switch SW2 off (0) in order
to minimize risk of damage to modules.
3. Pull out and lift the lever if replacing a
Control or Power Module, then turn fastener
counter-clockwise until it is loosened.
4. Start to pull out module. About 2/3 out it will
stop. Slide module away from the center of
the UPS. CAUTION: Battery Modules
are heavy (30 kg). Make sure to use two
people when removing a Battery Module.
Continue to pull until module is removed.
(Seen at right)
WARNING
POTENTIAL TIP HAZARD
Install all modules starting from
bottom to top bays.
For module
removal, start from top to bottom
bays. Do Not remove more than one
module at a time. Failure to do so
may cause unit to tip over and cause
serious injury.
5. Dispose of module in an environmentally
responsible way that complies with local
codes / regulations or return to Liebert for
proper disposal.
Note: Battery Modules may contain shipping
screws. These screws may be removed and
discarded.
35
Replacing Modules
Replacing the User Interface
1. Lift module to appropriate bay, resting end
of module on bay shelf. Use caution not to
rest the module on the lower bezel cover.
1. Lift off user interface and set it on top of the
UPS frame.
2. The attached cable will be connected to an
Intellislot card, found in a port between the
control modules.
2. Push module into bay. Once half way in,
slide module sideways toward the center of
the UPS. Continue pushing module until
fully inserted.
3. Press and turn fastener clockwise until
locked. If replacing a Control or Power
Module, press lever down.
3. Disconnect the cable from the Intellislot
card.
4. Plug the new user interface cable into the
Intellislot card.
4. Wait about 15 seconds as the module
performs a start-up test and synchronizes
with the other modules. Both the amber and
green LEDs should be flashing. A green
flashing LED will then confirm the module is
properly connected.
5. Set replacement User Interface into proper
position.
5. If UPS was placed in bypass manually,
transfer back to UPS operation.
6. Replace bezels.

Replacing Fan Filters
Keeping your Liebert Nfinity UPS operating
properly is imperative to optimal performance
and life of the unit. It is recommended that a
certified technician perform preventive and
corrective maintenance. Liebert Global Services
(LGS) is dedicated to ensuring the highest level
of performance and unmatched support for your
Nfinity UPS. Contact a LGS representative for
services to guarantee maximum reliability and
system availability.
Tranformer models only
Nfinity’s intake fans contain filters that will need
to be replaced / cleaned periodically, depending
on the surrounding environment. Check by
removing the bottom bezel and noting the
condition of the two filters. If filters are dirty,
replace them by removing the plastic cover over
the filter frame and inserting a new filter in its
place. Use caution when replacing filters when
fans are running.
Scheduled Maintenance
It is recommended the following maintenance is
performed at least monthly:
§ Clean unit
§ Clean / replace filters
§ Verify proper airflow
It is recommended the following maintenance is
performed annually:
§ Verify all power modules are operating
properly.
§ Verify all battery modules are operating
properly.
§ Verify redundancy (if applicable).
The fan filters are washable and can be reused.
To wash filters, place them under a running
faucet (with the dirt side down) to remove dirt
and dust.
Blot dry with a towel and allow airdrying before reusing.

Warranty
LIMITED WARRANTY
Liebert Corporation extends the following LIMITED WARRANTY to the
purchaser and to its customer (collectively referred to as the "Purchaser"):
the enclosed Uninterruptible Power System (UPS) and components are
free from defects in materials and workmanship under normal use,
service, and maintenance FOR A PERIOD OF TWO YEARS FROM THE
DATE OF ORIGINAL PURCHASE from Liebert or the Liebert dealer or
retailer. THE FOREGOING WARRANTY IS THE ONLY WARRANTY
GIVEN AND NO OTHER WARRANTY IS PROVIDED, EXPRESS OR
IMPLIED, INCLUDING WITHOUT LIMITATION, MERCHANTABILITY OR
FITNESS FOR A PARTICULAR PURPOSE. Certain aspects of
disclaimers are not applicable to consumer products acquired by
individuals and used for personal, family, or household purposes (as
distinguished from industrial or other purposes). Local laws may not allow
limitations on how long an implied warranty lasts, so the above limitation
may not apply to you. This warranty gives you specific legal rights, and
you may have other rights, which vary according to local law.
Certain repairs or services are the responsibility of the Purchaser and the
Purchaser is expected to pay for them. This warranty does not extend
either to products with removed or altered serial numbers or to any losses
or damages due to act of God or source external to the product, misuse,
accident, abuse, neglect, negligence, unauthorised modification,
alteration, or repair, use beyond rated capacity, or improper installation,
maintenance, application or use, including, without limitation, use in a
manner contrary to the accompanying instructions or applicable codes.
WARNING: Warranty is void if the battery is allowed to discharge below
the minimum battery cut-off point. The battery must be recharged every
four (4) to six (6) months when not in use.
If the UPS fails to conform to the above warranty within the two-year
warranty period, Liebert will repair or replace the UPS, at Liebert's option.
Repairs or replacements are warranted for the remainder of the original
warranty period. Purchaser, to make a warranty claim, should call to
obtain a Returned Goods Authorisation number and shipping instructions.
Return transportation costs to Liebert are the responsibility of the
Purchaser.
"LIFE SUPPORT" APPLICATIONS
Due to the diversity of applications and considerations to be applied in
each case, Liebert does not recommend or knowingly sell its products for
such use.
The responsibility for risk assessment and management in applications
where the malfunction or failure of the UPS could be reasonably expected
to give rise to a risk of human life shall be the sole responsibility of the
purchaser. Liebert accepts no liability for consequential harm in such
applications.
