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.

The UPS also incorporates advanced technologies such as double-conversion online architecture, which provides the highest level of power quality. This technology ensures that the output power is consistently clean and stable, effectively eliminating harmful voltage fluctuations and frequency variations. Consequently, connected load receives a pure sine wave output, preventing potential damage or operational issues with sensitive equipment.

Another key feature is the high efficiency rating of the Emerson UPS, which exceeds 95 percent in typical operating conditions. This high efficiency translates to reduced energy costs and a smaller carbon footprint, aligning with modern sustainability goals. The cooling system is designed to be efficient as well, ensuring optimal performance while maintaining a compact footprint.

The user-friendly interface enhances operability, featuring an intuitive LCD display that allows for easy monitoring of critical power parameters. Users can access real-time data related to battery health, load levels, and operational status, which aids in effective management of the power supply.

Battery management is another critical aspect of the Emerson UPS. It employs advanced battery management technologies to ensure optimal battery life and performance. Features such as intelligent battery testing and monitoring help predict potential battery failures before they occur, allowing for proactive maintenance and minimized downtime.

In summary, the Emerson 10-30 kVA, 208V UPS offers a combination of modularity, high efficiency, advanced technologies, and effective power management features that cater to the demanding needs of critical applications. With its reliable performance and user-friendly operation, this UPS solution is an excellent choice for organizations looking to protect their valuable equipment from power disturbances.
