LIMITED WARRANTY 

 
Liebert Corporation extends the following LIMITED WARRANTY to the 
purchaser and to its customer (collectively referred to as the "Purchaser"): the 
enclosed Uninterruptible Power System (UPS) and components are free from 
defects in materials and workmanship under normal use, service, and 
maintenance FOR A PERIOD OF TWO YEARS FROM THE DATE OF 
ORIGINAL PURCHASE from Liebert or the Liebert dealer or retailer. THE 
FOREGOING WARRANTY IS THE ONLY WARRANTY GIVEN AND NO 
OTHER WARANTY IS PROVIDED, EXPRESS OR IMPLIED, INCLUDING 
WITHOUT LIMITATION, MERCHANTABILITY OR FITNESS FOR A 
PARTICULAR PURPOSE. Certain aspects of disclaimers are not applicable to 
consumer products acquired by individuals and used for personal, family, or 
household purposes (as distinguished from industrial or other purposes). Local 
laws may not allow limitations on how long an implied warranty lasts, so the 
above limitation may not apply to you. This warranty gives you specific legal 
rights, and you may have other rights which vary according to local law. 
Certain repairs or services are the responsibility of the Purchaser and the 
Purchaser is expected to pay for them. This warranty does not extend either to 
products with removed or altered serial numbers or to any losses or damages 
due to act of God or source external to the product, misuse, accident, abuse, 
neglect, negligence, unauthorized modification, alteration, or repair, use beyond 
rated capacity, or improper installation, maintenance, application or use, 
including, without limitation, use in a manner contrary to the accompanying 
instructions or applicable codes. WARNING: Warranty is void if the battery is 
allowed to discharge below the minimum battery cutoff point.  To prevent such 
discharge DO NOT leave the unit power switch "ON" for more than two (2) days 
without AC power being supplied to the UPS. The battery must be recharged 
every four (4) to six (6) months when not in use. 
If the UPS fails to conform with the above warranty within the two year warranty 
period, Liebert will repair or replace the UPS, at Liebert's option.  Repairs or 
replacements are warranted for the remainder of the original warranty period. 
Purchaser, to make a warranty claim, should call 1-800-222-5877 to obtain a 
Returned Goods Authorization number and shipping instructions. Return 
transportation costs to Liebert are the responsibility of the Purchaser.
