Emerson 60HZ- Manual

1

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 com-

bines a rack form factor, advanced operating fea-

tures 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.
