1 GXT5 DESCRIPTION The Liebert® GXT5 is a compact, online uninterruptible power system (UPS) that continuously conditions and regulates its output voltage. The Liebert® GXT5 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.
16-kVA to 20-kVA models is the same in a rack or tower configuration.

1.6 Major Internal Components and Operating Principle Figure 1.12 below, shows the UPS operating principle. Table 1.2 on the next page, describes the function of the major components in the UPS. NOTE: Figure 1.12 below, is one example of basic operation. The actual I/O connections for the various models may be divided into different types.
The charger charges the battery in normal mode. On the front- panel display, the run-indicator (green) is On, the alarm indicator is OFF, and the buzzer is silent. Figure 1.13 on the facing page, shows a diagram of normal mode. Vertiv | Liebert® GXT5™ Installer/User Guide...
Figure 1.13 Normal-mode Operation ITEM DESCRIPTION Mains/Utility input (by-pass input) Rectifier/PFC Inverter Battery charger Battery Bypass static switch UPS output 1.7.2 Bypass Mode Bypass mode supplies power to the load from the bypass source (utility power) if an overload or fault occurs during normal operation.
8 hours before first start-up. NOTE: If utility power fails and the batteries are charged, you may cold-start the UPS in battery mode and use battery power to extend system availability for a time. Vertiv | Liebert® GXT5™ Installer/User Guide...
Figure 1.15 Battery-mode Operation ITEM DESCRIPTION Mains/Utility input (by-pass input) Rectifier/PFC Inverter Battery charger Battery Bypass static switch UPS output 1.7.4 ECO Mode NOTE: ECO mode is only available on a single-UPS system. The energy-saving ECO mode reduces power consumption by powering the load via bypass if the bypass voltage is normal or by powering the load via the inverter when the bypass voltage is abnormal.
UPS may shut down without notice and shut-off output power to the load. NOTE: The UPS has no user-serviceable parts. If the UPS malfunctions and requires service, visit http://www.VertivCo.com/en-us/support/ or contact your local Vertiv representative. Vertiv | Liebert® GXT5™ Installer/User Guide...
Unpack the UPS and conduct the following checks: • Inspect the UPS for shipping damage. If any shipping damage is found, report it to the carrier and your local Vertiv representative immediately. • Check the accessories included against the packing list. If there is any discrepancy, contact your local Vertiv representative immediately.
CAUTION: The GXT5 is heavy. The UPS must be installed as near the bottom of a rack as possible. If placed too high, it can make the rack top-heavy and prone to tipping over. For unit weights, see Specifications on page 61. Vertiv | Liebert® GXT5™ Installer/User Guide...
• Refer to the instructions included with the rack-mount kit to install. NOTE: Optional slide rails and securing hardware and are sold separately. Please contact your Vertiv representative for options and Vertiv Technical Support for assistance. 3. Verify the that the EBC breaker is in the "Off" position.
POD options compatible with your GXT5 model. NOTE: Do not operate the UPS with the POD removed. To shut off all power to the POD and to the load, utility input power must be disconnected. Vertiv | Liebert® GXT5™ Installer/User Guide...
To attach the POD on 16-kVA to 20-kVA units: On the rear of the unit, unscrew the two fixing screws from the POD-location cover, see Figure 2.3 below, and remove the cover. 2. Insert the POD receptacles into the ports, and connect the PP75 terminal. 3.
The input circuit breaker on the distribution box does not disconnect power from the manual bypass breaker.

2.6.3 Connecting to Terminal Blocks on 5-kVA and 6-kVA models These models offer a single type of I/O connection, 1-in 1-out common source. Figure 2.5 below, shows the terminal block. Refer to the details in Terminal-block Connections on page 27, when making the connections.
Figure 2.10 below, shows the ports and Table 2.4 on the facing page, describes each port. The I/O dry contact port capacity is 125 Vdc, 0.5 A; 30 Vdc, 1 A Figure 2.10 Dry-contact Port and Pin Layout NOTE: Pins 7 and 8 are shorted before delivery. Vertiv | Liebert® GXT5™ Installer/User Guide...
NOTE: The emergency power-off (EPO) action of the UPS closes the rectifier, inverter and static bypass, but it cannot disconnect the UPS mains input inside. To completely disconnect the UPS, disconnect the upstream input circuit breaker when generating the EPO. For details on REPO connection and operation, see Connecting a Remote Emergency Power-off (REPO) Switch below.
The standard, B-type USB port connects the UPS to a network server or other computer system. The USB port supports HID/CDC protocol. The CDC protocol is reserved for service software. To use the HID protocol for monitoring, get the HID protocol from www.VertivCo.com. Vertiv | Liebert® GXT5™ Installer/User Guide...
— — 2.7.6 Connecting Sensors to the Control Port The UPS supports the Vertiv temperature and temperature/humidity sensors. The RJ-45 port is used for sensor connection. See the appropriate figure for your model in Rear Panels on page 4, for the location of the port.
Page 40
NOTE: 8-kVA models do not support parallelling at this time. NOTE: You must use Vertiv parallel cables for the connection. NOTE: If a fault occurs during parallel-system operation, shut-off the system and make sure the cables are connected correctly, see Figure 2.12 below.
2.8.1 First-time Start-up of Parallel System IMPORTANT! Do not start the UPS until after the installation is finished, the system is commissioned by an authorized engineer, and the external input circuit breakers are closed. CAUTION: Starting the UPS applies mains/utility power to the output terminals. Make sure that the load power is safe and ready to accept power.
4. On the added UPS, close the external I/O switches, wait about 30 seconds to allow the rectifier start-up to finish, then power-on the inverter. 5. Make sure that there are no alarms and that the UPS and the parallel system are operating normally. Vertiv | Liebert® GXT5™ Installer/User Guide...
3 OPERATING THE UPS 3.1 Silencing the Audible Alarm The audible alarm may sound during UPS operation. To silence the alarm, press and hold the ESC button for 2 seconds. The button is located on the front-panel display, see Operation and Display Panel page 41.
To manually power-off in an emergency, disconnect the terminal connecting the REPO port on the rear of the UPS. If mains/utility power is present, the UPS control circuit remains active even though output power is disabled. To remove all mains/utility power, disconnect the external main-input MCB.

Read all safety cautions before proceeding. A trained user can replace the internal battery pack when the UPS is in a restricted access location (such as a rack or server closet). To obtain the appropriate replacement battery pack(s), refer to Table 5.1 below, and contact your local dealer or Vertiv representative.
6. Line-up and slowly push-in each replacement battery pack. until 2/3 of the length is in the bay, then lift up and continue to push smoothly until the battery pack is fully inserted in the bay. The battery is fully-inserted if the battery door fits flush against the UPS. 7.
Vertiv Technical Support. 6. Check to see if batteries are discharging (operating in Battery mode) and utility power is normal. If so, contact Vertiv Technical Support. 5.4 Cleaning the UPS WARNING! Risk of electric shock. Can cause injury or death. Disconnect all local and remote electric power supplies before working with the UPS.
