installation and maintenance of the UPS and batteries, allowing you to correctly set up your system for
the maximum safety and performance. Included is information on customer support and service, if it is
required. If you experience a problem with the UPS, please refer to the Troubleshooting section in this
manual to correct the problem. If the problem is not corrected, please collect information so that the
Technical Support personnel can more effectively assist you.
WARNING: Any changes or modifications not expressly approved by the manufacturer of this
device could void the user’s authority to operate the equipment.
IMPORTANT SAFETY INSTRUCTIONS:
(SAVE THESE INSTRUCTIONS)
CAUTION! (UPS having Internal Batteries): Risk of electrical shock – Hazardous live
parts inside this unit are energized from the battery supply even when the input AC power is
disconnected.
CAUTION! (No User serviceable Parts): Risk of electrical shock, do not remove cover.
No user serviceable parts inside. Refer servicing to qualified service personnel.
CAUTION! (Non-isolated Battery supply): Risk of electric shock, battery circuit is not
isolated from AC input, hazardous voltage may exist between battery terminals and ground. Test before
touching.
WARNING! (Fuses): To reduce the risk of fire, replace only with the same type and size of fuse.
WARNING! Unit intended for installation in a controlled environment.
CAUTION! Do not dispose of batteries in a fire, the battery may explode.
CAUTION! Do not open or mutilate the battery, released electrolyte is harmful to the skin and eyes.
CAUTION! A battery can present a risk of electric shock and high short circuit current. The following
precaution should be observed when working on batteries:
•Remove watches, rings or other metal objects.
•Use tools with insulated handles.

NXRTi USER’S MANUAL UNINTERRUPTIBLE POWER SUPPLY (UPS)
Xtreme Power Conversion Corporation (Rev 8/29/13) Page 5
To reduce the risk of electric shock, disconnect the UPS from the main supply before installing a
computer interface signal cable. Reconnect the power cord only after signaling interconnections have
been made.
Servicing of batteries should be performed or supervised by personnel with knowledge of batteries and
the required precautions. Keep unauthorized personnel away from batteries.
These UPS units are extremely heavy. Do not install the UPS in a rack or enclosure by its front two ears
only. Adjustable rack rails are required for this type of installation.
The instructions contained within this safety manual are deemed important and should be closely
followed at all times during installation and follow-up maintenance of the UPS and batteries.
CAUTION
The unit has a dangerous amount of voltage. If the UPS indicator is on, the unit’s outlets may have a
dangerous amount of voltage even when not plugged into the wall outlet because the battery may
continue to supply power.
Care should be taken to undertake installation indoors, free from electrically-conductive particles
which are under temperature and humidity control, in order to reduce the risk of electric shock.
It is best to disconnect the device using the power supply cord. Ensure that the equipment is placed in
a position near the outlet where easily accessible.
Except for replacing the batteries, all servicing on this equipment must be carried out by qualified
service personnel.
Before conducting any maintenance, repair, or shipment, first ensure that everything is turned off
completely and disconnected.
For additional safety instructions, please use the Safety Manual as a reference.
Special Symbols
The following symbols used on the UPS warn you of precautions:

sales terminals, other critical instrumentation, etc. The purpose of the UPS is to protect these systems
from poor quality utility power, complete loss of power, or other associated problems.
Electrical interference exists in many forms, causing problems in AC power, from lightning, power
company accidents and radio transmission motors, air conditioners, and vending machines. Protection
of sensitive electrical equipment is vital to protect against power outages, low or high voltage
conditions, slow voltage fluctuations, frequency variations, differential and common-mode noise,
transients, etc.
To prevent power line problems from reaching critical systems causing damage to software, hardware,
and equipment malfunctions, the UPS maintains constant voltage, isolating critical load output and
cleaning the utility AC power.
Double Conversion On-Line Technology
A double conversion on-line technology UPS provides completely isolated, clean, uninterrupted single-
phase power to your critical systems, while maintaining the batteries for their maximum potential. In
the event that the power failure lasts longer than the UPS backup time, the UPS will shut down avoiding
battery damage. When the input AC voltage returns, the UPS will automatically return online to
recharge the batteries.
As shown in fig. 1 block diagram:
•An input filter reduces transients on the incoming utility.
•To maintain full battery charge, the AC input power is rectified and regulated in the rectifier
feeding power to the battery converter and inverter.
•DC power is converted to AC in the inverter, passing it on to the load.
•Power is maintained from the battery during a power failure.
•The converter increases voltage appropriately for the inverter.

Functions and Characteristics
•Advanced IGBT modules are used in our UPS, with electronics that will work for more than
300,000 hours.
•Digital Control Technology with high efficiency algorithm delivers a most reliable controller
design used to optimize the output parameters of the UPS.
•The UPS performs a Self-Diagnostic Test before starting, enabling the UPS to detect and correct
any potential problems prior to powering up the load.
•Double Conversion On-Line Topology makes the output of the UPS a pure sine wave with
consistent frequency and voltage regulation, low noise, and no interruption in power to the load
when utility power is lost.
•Zero Transfer Time when the utility power fails or returns.
•The UPS has a Bypass Function that allows for the load to be transferred to a bypass mode
when a UPS fault occurs. No interruption in power occurs to the load and an alarm will alert to
this occurrence. This feature also allows for configuring the UPS to support fully rated loads of
switching power supplies, as the bypass circuit can handle the start up.
•Advanced Voltage Compensation Technology allows the input voltage range to be 115VAC to
295VAC, reducing battery usage and enhancing UPS response during utility power fluctuations.
•Advanced Wide Input Frequency Technology enables the UPS to perform from 45 to 55 Hz
when 50Hz output is selected, or 55 to 65 Hz when 60Hz output is selected. All of this means
that the UPS is very compatible with single-phase generator operation.
•Advanced Power Factor Correction (PFC) Technology on the input of the UPS makes the input
power factor more than 0.98, increasing power efficiency, removing harmonic noise, and lowers
the UPS operational cost.
•Auto Start on Battery allows the UPS to start in battery mode when utility power is not
available.
•Rack-Tower Conversion LCD means that the display can be read in Rack or Tower configurations
by only pressing a button – the display electronically rotates to provide the detailed information
in an easy-to-read manner.
•ECO Function can help to save electricity by allowing the UPS to operate in a line-interactive
mode. The load is supplied with utility power directly while the inverter is in a standby mode
until needed.

SYSTEM CONFIGURATION
The UPS device and the internal batteries make up the system. Depending on the site and load
requirements of the installation, certain additional options are available for the solution.
Planning a UPS system, the following should be taken into consideration:
•The total demand of the protected system shall dictate the output power rating (VA). Allow a
margin for future expansion or calculation inaccuracies from measured power requirements.
•Backup time required will indicate the battery size needed. If the load is less than the UPS
nominal power rating, then actual backup time is longer.
•The following options are available:
oExtended Battery Packs
NXRTi-EBP1 for 1000
NXRTi-EBP2 for 2000
NXRTi-EBP3 for 3000
oConnectivity Options –SNMP/WEB card
oXtreme Power Distribution Units (XPDU)
