Npower™ 3-Phase UPS: 30 to 80 kVA, 208 or 480VAC, 60 Hz
•
Unmatched heritage of reliability and
availability
•
Smallest system footprint
•
Excellent efficiency with non-linear loads and
partial loads
•
Outstanding dynamic response
•
All-digital ActiveStar™ controls and graphical
user interface
The Npower is a true double-conversion UPS, the
result of an international design collaboration and
more than a decade of advanced research.
The rugged power train and advanced ActiveStar™
controls were subjected to computer simulations and
accelerated life testing to ensure reliable performance
in every type of electrical environment.
Even the physical packaging is uniquely efficient, to
make fully configured systems more compact than its
competitors.
Best of all, it’s a Liebert product – designed to give
the same million-hour critical bus MTBF as other
Liebert UPS products.

NOTES FOR TABLE:
1. Nominal (Nom) current is based on full rated output load.
2. Maximum (Max) current (125% of nominal) is short duration for battery recharge
conditions.
3. UPS input and bypass cables must be run in separate conduit from output
cables.
4. Nominal battery voltage is shown at 2.0 volts/cell per NEC 480-2.
5. Power cables from UPS DC link to batteries should be sized for a total maximum
2.0 volt line drop (measured at the UPS) at maximum discharge current.
6. Recommended AC input and AC output overcurrent protection represents 125%
of nominal full load current (continuous) plus non-continuous loads per NEC 215.
7. Minimum-sized grounding conductors to be per NEC 250-122. Parity-sized
ground conductors are recommended. Neutral conductors to be sized for full
capacity per NEC 310-15(b)(4). References are per NEC 1999.
8. Wiring requirements:
AC Input:
3-phase, 3-wire plus ground or
3-phase, 4-wire plus ground
AC Output: 3-phase, 4-wire plus ground
DC Input:
2-wire (positive and negative), plus ground
9. All wiring is to be in accordance with national and local electrical codes.
10. Minimum access clearance is 3 feet front and 1 foot above UPS.
11. Top or bottom cable entry through removable access plates. Punch plate to suit
conduit size, then replace.
12. Control wiring and power wiring must be run in separate conduit.
13. Weights and dimensions shown do not include battery cabinet, Slim-Line
distribution cabinet or other options.
14. OCPD=Overcurrent Protection Device.

ADDITIONAL NOTES:
•
•
•
If site configuration includes a back-up emergency generator, it is recommended
that the engine generator set be properly sized and equipped for a UPS
application. Generator options would typically include an isochronous governor
(generator frequency regulation) and a UPS-compatible regulator (generator
voltage regulation). Consult generator manufacturer for required generator
options and sizing.
If site configuration includes an automatic transfer switch, refer to the Liebert
Power Line titled “Criteria for Application of Automatic Transfer Switches (ATS)
with Uninterruptible Power Supply (UPS) Systems,” publication 91K-PLT-48-02.
It is also recommended that the transfer switch be equipped with auxiliary
contacts for UPS “on generator” current limit. Consult transfer switch
manufacturer for required transfer switch options and sizing.
If site configuration requires an external isolated maintenance bypass circuit, it
should be noted that utility AC input may not be in phase with the UPS AC
output. Consult Liebert sales representative or applications engineer.
