Battery Charging, Precautions, Checking UPS Status

Maintenance

6.2Battery Charging

The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their design life. The Liebert® GXT3™ charges the batteries continuously when it is connected to the utility input power.

If the Liebert GXT3 will be stored for a long time, Emerson recommends connecting the UPS to input power for at least 24 hours every four to six months to ensure full recharge of the batteries.

6.3Precautions

Although the Liebert GXT3 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 GXT3 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 Liebert GXT3.

•Do not place the Liebert GXT3 power cord where it might be damaged.

6.4Checking UPS Status

Emerson recommends checking the UPS operation status every six months.

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

•Check if 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 if the battery is discharging: When the utility input is normal, the battery should not dis- charge. If the UPS is operating in Battery Mode, stop and contact your local Emerson representa- tive or Emerson Channel Support.

6.5Checking UPS Functions

NOTE

UPS function check procedures may interrupt power supply to the connected load.

Emerson recommends checking the UPS functions once every six months.

Back up the load data before conducting the UPS functions check. Procedures are as follows:

1.Press the Standby/Manual Bypass button to check whether the alarm and indicators are normal.

2.Press the On/Alarm Silence/Manual Battery Test button to check again whether the indicators are On and the UPS is operating normally.

3.Press the On/Alarm Silence/Manual Battery Test button for three seconds after Inverter Mode; the UPS should initiate battery self-test. Check to determine whether the battery is operating normally. If not, stop and contact your local Emerson representative or Emerson Channel Support.

GXT3, 208V specifications

The Emerson 10-30 kVA, 208V uninterruptible power supply (UPS) solution is a robust system designed to provide reliable power protection for critical applications in commercial and industrial settings. This UPS is ideal for safeguarding IT equipment, communication systems, and other sensitive electronics against power disturbances and interruptions.

One of the standout features of the Emerson 10-30 kVA UPS is its modular design, allowing for flexibility and scalability.
