INTRODUCTION AND SYSTEM DESCRIPTION

Congratulations on your choice of the Liebert GXT5000R-208 Uninterruptible Power System (UPS). It provides conditioned power to microcomputers and other sensitive electronic equip­ment.
Upon generation, AC power is clean and stable. However, during transmission and distribu­tion it may be subject to voltage sags, spikes, or complete power failure that may interrupt computer operations, cause data loss, and even damage equipment. The GXT5000R-208 pro­tects equipment from these disturbances.
The GXT5000R-208 has a nominal power rating of 5,000VA, 3,750 W. Complete model specifi­cations appear at the end of this manual.
At least one external battery cabinet must be connected to the GXT5000R-208 to form a com­plete “on-line” UPS system. Two different models of battery cabinets are available:
• The GXT5VBATT provides batteries only.
• The GXT5VBATTW120 provides batteries and an auxiliary transformer to provide up to 400VA at 120V.
Both battery cabinets provide two battery connectors to allow the daisy-chain connection of additional battery cabinets. The UPS may be used with either battery cabinet, depending on whether the additional 120V / 400 VA power supply is needed.
For applications requiring 120V, one GXT5VBATTW120 should be the first battery cabinet located adjacent to the GXT5000R-208. The GXT5000R-208 requires a one-foot interconnect cable to provide power to the internal 208 V step-down transformer.
If more than one battery cabinet is desired for additional backup battery time, additional GXT5VBATTs can be added. Only one GXT5VBATTW120 external battery cabinet can be used per UPS system.
For ease of use, the GXT5000R-208 utilizes light emitting diode (LED) displays to indicate “load percentage” and “battery capacity,” and fault indications. It also provides a self-diagnos­tics test, a combination ON/Manual Battery Test button, a combination Standby / Manual Bypass button, and a variety of relay alarm contacts.

MAJOR COMPONENTS

Transient Voltage Surge Suppression (TVSS) & EMI/RFI Filters

These UPS components provide surge protection and filter both electromagnetic interference (EMI) and radio frequency interference (RFI). They minimize any surges or interference present in the utility line and keep sensitive equipment protected.

Rectifier/Power Factor Correction (PFC) Circuit

In normal operation, the rectifier/PFC circuit converts utility AC power to regulated DC power for use by the inverter while ensuring that the waveshape of the input current used by the UPS is near ideal. Extracting this sinewave input current achieves two objectives: the utility power is used as efficiently as possible by the UPS, and the amount of distortion reflected on the utility is reduced. This results in cleaner power being available to other devices in the building not being protected by the GXT5000R-208.

Inverter

In normal operation, the inverter utilizes the DC output of the power factor correction circuit and “inverts” it into precise, regulated sinewave AC power. When utility power fails, the inverter takes power from the battery through the DC to DC converter and inverts it into alternating current. In both modes of operation, the UPS inverter is on-line and continuously generating clean, precise, regulated AC output power.

Battery Charger

The battery charger utilizes utility power and precisely regulates it to continuously “float” charge the battery system.

DC to DC Converter

The DC to DC converter utilizes energy from the battery system and raises the DC voltage to the optimum operating voltage for the inverter. This allows the inverter to operate continu­ously at its optimum efficiency and voltage, thus increasing reliability.

Battery

The GXT5VBATT and GXT5VBATTW120 employs valve-regulated, nonspillable, lead acid batteries. At an ambient temperature of 68°F to 77°F (20°C to 25°C) and with the UPS float charging, the battery design life will be maintained.
5
Auxiliary 120V / 400VA Power
The GXT5VBATTW120 battery cabinet also provides a transformer to provide up to 400VA of 120V power.

Dynamic Bypass

The GXT5000R-208 provides an alternate path for utility power to the connected load in the unlikely event of a UPS malfunction, such as overload, overtemperature, or an internal UPS failure. If a malfunction does occur, the UPS automatically transfers the connected load to bypass. Bypass operation is indicated by an alarm and illuminated Bypass LED (other LEDs also may be illuminated to indicate the diagnosed problem). To manually transfer the con­nected load from the inverter to bypass, press the Standby button once.
NOTE
The bypass power path does NOT protect the connected equipment from disturbances on the utility supply, such as spikes, sags, and failure.

OPTIONAL BATTERIES - PROGRAMMABLE RUN TIME

The GXT5000R-208 may be equipped with up to five battery GXT5VBATT cabinets. At least one battery cabinet is required. The first battery cabinet may be a GXT5VBATTW120 if a 120V, 400VA auxiliary voltage source is needed.
The enhanced communication provides an estimated run time in minutes, taking into account the number of battery cabinets and UPS load. The number of attached battery cabinets must be programmed into the UPS for accurate time estimates.
Even when external monitoring software is not used, the enhanced accuracy is applied to the low battery contact closure alarm provided by the standard relay alarm card.
The front control panel provides a convenient method of programming the number of battery cabinets.

Programming the GXT5000R-208 for Battery Cabinet Count

Programming the UPS uses the ON button, the Standby button, and the Load LEDs on the front control panel (see illustration at right).
The battery count display mode should be entered only with the UPS load off.
Once the battery count is displayed, the user has the option of leaving the battery count unchanged or modifying the count to match the number of attached battery cabinets.
The count should always be checked on new installations to confirm the setting.
In this mode, the Load LEDs function as Bat­tery Count LEDs. On completion of the pro­cedure, one to five Load LEDs illuminate to indicate how many battery cabinets are con­nected to the GXT5000R-208 (see illustration below).

Procedure to confirm the battery count

1. Apply AC input power to the UPS.
2. Turn the UPS output off using the Standby button. If the UPS is in inverter mode, the load must first be transferred to bypass and then to off.
3. Once the UPS output is off, press and hold the Standby button continuously. The Standby button must be held continuously for the duration of this procedure. The UPS will do nothing for the first 10 seconds. After approximately 10 seconds, the LED display will scroll and the horn will beep. When the LED display comes to rest (about 15 seconds after first pressing the Standby button), the battery cabinet count will be displayed on the Load LEDs. The count will display as long as the Standby button is continuously held.
4. If the Standby button is released at any time, the entire procedure must be restarted.
5. Once the battery count is displayed, or at any time if you wish to abort the procedure, you may release the Standby button and restart the UPS using the ON button.

Procedure to change the battery count

This procedure required the simultaneous use of the Standby button and ON button. No other UPS procedure calls for simultaneously pressing the Standby and ON buttons.
The first three steps of this procedure repeats Steps 1 through 3 in the Procedure to con- firm the battery count. However, once the battery count is displayed, you have the option of changing the count. As before, the Standby button must be held continuously for the entire procedure. Releasing the button prematurely will require that the whole process be repeated.
1. Apply AC input power to the UPS.
2. Turn the UPS output off using the Standby button. If the UPS is in inverter mode, the load must first be transferred to bypass and then to off.
3. Once the UPS output is off, press and hold the Standby button continuously. After approximately 10 seconds, the LED display will scroll and the horn will beep. When the LED display comes to rest (about 15 seconds after first pressing the Standby button), the battery cabinet count will be displayed on the Load LEDs. The count will display as long as the Standby button is continuously held.
4. If the displayed battery count is incorrect, press the ON button for 1 second while simultaneously continuing to hold the Standby button. The display will scroll and the horn will beep, and the battery count will be increased by one.
5. If the desired battery count has not been reached, repeat Step 4. The count can only be increased. After a count of 5 is reached, the count will restart at 1.
6. Once the desired battery count is displayed—or at any time you wish to abort the procedure—you may release the Standby button and restart the UPS using the ON button.

COMMUNICATIONS

17
EPO
This unit is equipped with provisions for the terminal connections for a UPS Emergency Power OFF Switch (EPO). The terminal is located on the rear of the UPS next to the DB-9 connector. If an EPO switch is used, it must have the characteristics of an emergency but­ton—closed under normal conditions and held open mechanically when operated. If this con­nection is removed, the unit will not start up.
Connections must not exceed NEC Class 2 limits.

UPS COMMUNICATIONS WITH INTELLISLOT

Your GXT5000R-208 comes equipped with the RELAYCARD-INT relay card. The addition of serial communications now expands the list of cards that may be used in the Intellislot.
The UPStation GXT5000R-208 UPS is equipped with an Intellislot bay to provide advanced communication and monitoring options.
Liebert’s MultiLink™ software continually monitors the UPS via a serial cable and can shut down your computer or server in the event of an extended power failure.
MultiLink can also be configured for use without the serial cable when the Intellislot SNMP/ Web card is installed in the UPS. Additionally, MultiLink can be configured to coordinate shutdown across the network with other computers running MultiLink when you purchase a MultiLink License Kit. For more information about the Intellislot SNMP/Web Card and Mul­tiLink License Kits, please visit the Web site http://multilink.liebert.com or contact your local dealer or Liebert representative.
Several option cards are available for use in the Intellislot bay of the UPStation GXT5000R-
208. The Intellislot SNMP/Web Card provides SNMP and Web-based monitoring and control of the UPS across the network.
The Intellislot MultiPort 4 Card allows you to install MultiLink software on four computers and coordinate an orderly shutdown in the event of a power failure.
The standard Intellislot Relay Card provides dry contact relay outputs for custom-wired applications and delivers support for built-in shutdown for AS/400 systems.
CAUTION
!
TO MAINTAIN SAFETY (SELV) BARRIERS AND FOR ELECTROMAGNETIC COMPATIBILITY, SIGNAL CABLES SHOULD BE SEGREGATED AND RUN SEPARATE FROM ALL OTHER POWER CABLES, WHERE APPLICABLE.
20

MAINTENANCE

The GXT5000R-208 UPS requires very little maintenance. The batteries are valve-regulated, nonspillable, lead acid and should be kept charged to obtain their design life. The UPS contin­uously charges the batteries when connected to the utility supply.
When storing the UPS for an extended period, connect it to utility power for at least 24 hours every six months to keep the batteries fully charged.
CAUTION
!
Only qualified service personnel may replace internal batteries in the battery cabinets.
