Liebert GXT3-8000RT208 Manuel D’Utilisation

Liebert GXT3 5-10kVA UPS 
systems may be purchased as part 
of the Liebert Power Assurance 
Package. While today’s smaller, 
rack-based UPS systems offer 
relatively trouble-free operation, 
the growing criticality of the 
systems they support has 
increased the cost of downtime. 
As a result, the need to maintain 
these smaller UPS systems is 
increasingly important.
This all-inclusive package offers 
you complete peace-of-mind for 
five years including:
UPS — A compact, high quality 
on-line Liebert GXT3 UPS (5, 6, 8 
or 10kVA).
Start-up — On-site system  
start-up by a certified Emerson 
Network Power Customer 
Engineer, scheduled anytime, 24 
x 7. This includes removal and 
disposal of your existing UPS.
Preventive maintenance — 
One preventive maintenance 
visit completed in year 3 by a 
certified Emerson Network Power 
Customer Engineer includes 100% 
Parts Coverage — even internal 
batteries. 
Full parts coverage — Your 
on-line Liebert UPS benefits 
from 100% parts coverage for 
five years, including all internal
