INTRODUCTION
The information provided in this manual covers single phase 6000 and 10000 VA uninterruptible power
systems, their basic functions, operating procedures, options available and emergency situations. It also
includes information on how to ship, store, handle, and install the equipment. Only detailed
requirements of the UPS units are described herein, and installation must be carried out in accordance
with this manual. Electrical installation must also carefully follow local legislation and regulations. Only

PRODUCT DESCRIPTION
Many different kinds of sensitive electrical equipment can be protected by an Uninterruptible Power
Supply (UPS) including computers, workstations, process control systems, telecommunications systems,
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

NXRi-6KL, NXRi-10KL USER MANUAL UNINTERRUPTIBLE POWER SUPPLY (UPS)
Xtreme Power Conversion® (XPC) Corporation (Rev 2/7/13) Page 10
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.
Figure 1 – Block Diagram
Diagnostic Tests
When the UPS is started, a diagnostic test is automatically executed, checking the electronics and
batteries, reporting any problems on the LCD display. A diagnostic test can also be performed manually
from the front panel at any time.

SYSTEM CONFIGURATION
The UPS device and the Extended Battery Pack (EBP) 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 Pack
NXR-EBP20 for use with NXRi-6K and NXRi-10K
oConnectivity Options –SNMP/WEB card
See the Specification section of this manual for additional model information.
