Emerson 40-120KVA, 60HZ, 480VAC User Manual
LIEBERT® NX™ 3-PHASE UPS: 40-120KVA, 60HZ, 480VAC - SITE PLANNING DATA
The Liebert NX is a true on-line, double conversion,
three-phase UPS system that delivers complete,
centralized power protection for mission-critical
systems.
Designed to meet the high availability power needs
of a wide variety of IT applications, the UPS combines a rack form factor, advanced operating features and low cost of ownership.
• Increases growth flexibility with Softscale™
technology, plus the ability to parallel modules
for increased capacity and redundancy.
• Achieves higher availability by reducing the
number of UPS units required to power your
data center.
• Reduces total cost of ownership through the use
of longer life batteries and simplified preventive
maintenance.

Notes for Table
1. Nominal (Nom) current is based on full rated output load at nominal input
voltage.
2. Maximum (Max) current (140% of nominal) is short duration for battery
recharge conditions and low input voltage.
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. For Single Input units only.
For Dual Input units, see “Electrical Data Specification Sheet, 40-120kVA
UPS Module, Single or Dual Input Liebert NX - U3819100.”
6. OCPD = Overcurrent Protection Device. Recommended AC input and AC
output overcurrent protection represents 125% of nominal full load current
(continuous) plus 100% of recharge current (non-continuous) 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
AC Output: 3-phase, 3-wire, plus ground
9. All wiring is to be in accordance with national and local electric codes.
10. Minimum access clearance is 3 ft. (0.9m) front and 8 in. (203mm) above
the UPS.
Notes for Table (continued)
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. Dimensions and weights in table do not include external battery cabinet.
Additional Notes
• Input and output wiring and breakers for a Liebert NX with Softscale technol-
ogy should be sized for the maximum scalable capacity. For example, a 40kVA
Liebert NX that is scalable to 80kVA should be installed with wiring and
breakers rated for an 80kVA configuration.
• If site configuration includes a backup emergency generator, it is recom-
mended 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 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 might not be in phase with the UPS AC
output. Consult a Liebert sales representative or applications engineer.
