5.1 Test, Replacement and Disposal of Batteries
The Liebert
®
GXT3
™
is designed to allow the user to replace the internal battery pack safely. Refer to
Table 7 for internal battery pack part numbers for Liebert GXT3 UPS and Liebert External Battery
Cabinets:
Read all safety cautions before proceeding. Contact your local dealer or Emerson representative to
obtain the part number and pricing of the appropriate replacement battery pack.
Disposal of the UPS and batteries should be carried out by a certified disposal company—observe all
local regulations and laws. Lead-acid batteries are classified as harmful toxic waste and as such the
law demands that they be disposed of by an authorized recycling centre.
The typical battery lifecycle is 3 to 5 years at an ambient temperature of 25 C, but is also dependent
on the frequency and duration of utility failures.
The BATTERY TEST (see 4.8.2 - Battery Test) should be run periodically (6 to 12 months) to
ascertain the general condition of the batteries and ensure maximum run time.
5.2 Storage
For extended storage at ambient temperatures cooler than 25°C (77°F), the batteries should be
charged for 24 hours once every six months.
Connect the UPS to a utility outlet socket having a ground (earth) connection and ensure the
miniature circuit breaker is closed. If charging batteries with fixed utility connections, make
connections in accordance with 3.0 - Installation.
After 24 hours, disconnect the UPS from the utility supply.
5.3 Cleaning
The UPS may be cleaned by wiping it off with a dry cloth. Do not use liquids or solvents.
