10. Reattach the front battery door with the six screws.

11. Reattach the front plastic bezel cover to the UPS.

6.2 Battery Charging

The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their

design life. The Liebert GXT4 charges the batteries continuously when it is connected to the mains

input power.

If the Liebert GXT4 will be stored for a long time, Emerson recommends connecting the UPS to input

power for at least 24 hours every three to four months to ensure full recharge of the batteries.

6.3 Precautions

Although the Liebert GXT4 has been designed and manufactured to ensure personal safety, improper

use can result in electrical shock or fire. To ensure safety, observe the following precautions:

• Turn Off and unplug the Liebert GXT4 before cleaning it.

• Clean the UPS with a dry cloth. Do not use liquid or aerosol cleaners.

• Never block or insert any objects into the ventilation holes or other openings of the UPS.

• Do not place the Liebert GXT4 power cord where it might be damaged.

6.4 Checking UPS Status

Emerson

recommends checking the UPS operation status every six months.

• Check whether the UPS is faulty: Is the Fault Indicator On? Is the UPS sounding an alarm?

• Check whether the UPS is operating in Bypass Mode. Normally, the UPS operates in Normal

Mode. If it is operating in Bypass Mode, stop and contact your local Emerson representative, or

Emerson Channel Support.

• Check whether the battery is discharging. When the mains input is normal, the battery should

not discharge. If the UPS is operating in Battery Mode, stop and contact your local Emerson

representative or Emerson Channel Support.

NOTE

The internal battery pack is hot-swappable. However, caution should be exercised because

during this procedure the load is unprotected from disturbances and power outages.

Do not replace the battery while the UPS is in Battery Mode. This will result in a loss of output

power and will drop the connected load.
