  • Page 9: Gxt4 Description

    2 GXT4 DESCRIPTION The Liebert® GXT4 is a compact, online uninterruptible power system (UPS) that continuously conditions and regulates its output voltage. The Liebert® GXT4 supplies microcomputers and other sensitive equipment with clean sine-wave input power. Upon generation, AC power is clean and stable. However, during transmission and distribution it is subject to voltage sags, spikes, and complete failure that may interrupt computer operations, cause data loss, and damage equipment.

    The battery charger utilizes energy from the utility power and precisely regulates it to continuously float charge the batteries. The batteries are being charged whenever the GXT4 is plugged in, even when the UPS is not turned On. Vertiv | Liebert® GXT4™ Installer/User Guide...

  • Page 17: Dc-To-Dc Converter

    2.5.5 DC-to-DC Converter The DC-to-DC converter raises the DC voltage from the battery to the optimum operating voltage for the inverter. This allows the inverter to operate continuously at its optimum efficiency and voltage, thus increasing reliability. 2.5.6 Battery The GXT4 uses valve-regulated, non-spillable, lead acid batteries. To maintain battery design life, Operate the GXT4 in an ambient temperature of 32°F to 77°F (0°C to 25°C).

  • Page 18: Operating Modes

    NOTICE Risk of loss of power to the connected load. Can cause equipment damage. Turning Off the UPS in Bypass Mode will result in loss of output power to the connected load. Vertiv | Liebert® GXT4™ Installer/User Guide...

  • Page 19: Battery Mode

    2.6.3 Battery Mode The GXT4 enters Battery Mode when mains power fails or is outside acceptable limits. The battery system supplies power through the DC-to-DC converter to the inverter to generate clean AC power for the connected loads. When the GXT4 enters Battery Mode, the UPS sounds a half-second beep at 10-second intervals. When approximately 2 minutes of run time remains, the beeps sound every 5 seconds to warn that the battery is getting low (this Low Battery Warning is user-configurable).
  • Page 20 Once bypass power returns within the acceptable parameters, the UPS will return to Active ECO Mode operation. The default setting is Active ECO Mode Off. Vertiv | Liebert® GXT4™ Installer/User Guide...
