1 IMPORTANT SAFETY PRECAUTIONS
SAVETHESEINSTRUCTIONS
This manual contains important safety instructions that must be followed during the installation and
maintenance of the UPS and batteries. Read this manual thoroughly before attempting to install or
operate this UPS. Adhere to all warnings on the unit and in this manual. Follow all operating and user
instructions. This equipment can be operated by individuals without previous training.
UPS Safety Notes
This UPS contains no user-serviceable parts except the internal battery pack. The Off/Bypass
pushbutton does not electrically isolate internal parts. Under no circumstances attempt to gain internal
access other than to replace the batteries due to risk of electric shock or burn. Do not continue to use the
UPS if the front panel indications are not in accordance with these operating instructions or if the UPS
performance alters in use. Refer all faults to your local dealer, Vertiv™ representative or Vertiv™ Channel
Support.
This UPS has an internal battery, and the output receptacles of the UPS may carry live voltage even if the
UPS is not connected to utility input power.
Before moving or rewiring this UPS, disconnect utility input power and the battery and make sure that the
UPS is completely shut down. Otherwise, the output terminal may carry live voltage, presenting an electric
shock hazard.
To ensure human safety and normal UPS operation, the UPS must be properly grounded before use.
When the UPS is connected to an IT power distribution system, a short-circuit protection device must be
installed on the neutral line.

2.7 Major Components
The UPS is composed of mains input, TVSS and EMI/RFI filters, rectifier/PFC, inverter, battery charger, DC-
to-DC converter, battery, dynamic bypass and UPS output.
Figure 2.9 Operating principle diagram
2.7.1 Transient Voltage Surge Suppression (TVSS) andEMI/RFIFilters
The UPS has surge protection and filters that protect the connected load from power surges,
electromagnetic interference (EMI) and radio frequency interference (RFI). These features can minimize
any surges or interference present in the mains power. The filters also prevent surges or interference
generated by the UPS from adversely affecting devices connected on the same branch as the UPS.
Vertiv | Liebert GXT4 Installer/User Guide | 19

2.7.2 Rectifier/Power Factor Correction (PFC) Circuit
In normal operation, the rectifier/PFC circuit converts mains power to regulated DC power for use by the
inverter while ensuring that the wave shape of the input current used by the UPS is near ideal. Extracting
this sine-wave input current achieves two objectives:
•Efficient power use by the UPS
•Reduced reflected harmonics
This results in cleaner power available to other devices in the building that are not protected by the
GXT4.
2.7.3 Inverter
In normal operation, the inverter utilizes the DC output of the PFC circuit to produce precise, regulated
sine-wave AC power. When mains power fails, the inverter receives DC power from the DC-to-DC
Converter. In either operation mode, the UPS inverter is online, continuously generating clean, precise,
regulated AC output power.
2.7.4 Battery Charger
The battery charger utilizes energy from the mains 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.
2.7.5 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.
2.7.6 Battery
The GXT4 uses valve-regulated, non-spillable, lead acid batteries. To maintain battery design life, Operate
the GXT4 in an ambient temperature of 15°Cto25°C (59°Fto 77°F).
Optional external battery cabinets are available to extend battery run times.
2.7.7 Internal Bypass
The GXT4 provides an alternate path for mains power to the connected load in the unlikely event of a
UPS malfunction. Should the UPS have an overload, over-temperature or any other UPS failure condition,
the UPS automatically transfers the connected load to bypass. Bypass operation is indicated by an
audible alarm and illuminated amber Bypass LED (other LEDs may be illuminated to indicate the
diagnosed problem).
To manually transfer the connected load from the inverter to bypass, press the Standby/Manual Bypass
button once and hold it for about 2 seconds
