Checking UPS Functions NOTE: UPS function check procedures may interrupt power supply to the connected load. We recommend checking the UPS functions once every 6 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 Vertiv™ representative or Technical Support

This section indicates various UPS symptoms you may encounter and provides a troubleshooting guide in the event the UPS develops a problem. Use the following information to determine whether external factors caused the problem and how to remedy the situation. 8.1 UPS Symptoms The following symptoms indicate the GXT4 is malfunctioning: • The relative indicators illuminate, indicating the UPS has detected a problem. • An alarm buzzer sounds, alerting the user that the UPS requires attention. 8.1.1 Indicator and LCD In addition to the fault indicator being illuminated, the LCD will display the fault. The displayed fault on the LCD is described in the following table NOTE: If the UPS encounters a fault and no correction attempt is performed within 2 minutes, the LCD backlight will flash (on 1 second and off 1 second) as an alert. Press any button to exit the alert mode. If no correction attempt is performed on the UPS, the LCD back light will flash again untilthe UPS fault is corrected.

Battery Charging 

The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to attain their design life. The GXT4 charges the batteries continuously when it is connected to the utility input power. If the GXT4 will be stored for a long time, We recommend connecting the UPS to input power for at least 24 hours every 4 to 6 months to ensure full recharge of the batteries. 7.3 Precautions Although the Liebert GXT4 is 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 GXT4 before cleaning it. • Wear rubber gloves and boots. • 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 GXT4. • Do not place the GXT4 power cord where it might be damaged. 7.4 Checking UPS Status We recommend 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 Vertiv™ representative or Technical Support. • Check if the battery is discharging: When the utility input is normal, the battery should not discharge. If the UPS is operating in Battery Mode, stop and contact your Vertiv™ representative or Technical Support.
