1 PRODUCT DESCRIPTION

The Liebert® EXS™ uninterruptible power system (UPS) is an intelligent, online UPS with sine wave

output. The UPS offers reliable, high-quality AC power to small-scale computer centers, networks,

communication systems, automatic control systems, and similar sensitive electronic equipment.

1.1 Model Configurations

Model Rating Input/Outpus

10 kVA - (208 and 220 V)

Single-input configuration (default), dual-input is field-configurable.

10 kVA - (208 and 220 V) with Battery Cabinet*

*Optional battery cabinet can only be ordered with internal batteries that are factory-installed.

Table 1.1 Model Configurations

1.2 Front-panel Components

The outside front panel of the UPS provides ventilation holes and an operation/display panel with LED

indicators and function keys. See Operation and Display Panel on page 31, for details about using the

display panel.

1.4 Major Internal Components and Operating Principle

The UPS is composed the components described in Figure 1.3 on the facing page. Table 1.2 below,

describes the operation of various circuits through the components.

Component Operation/Function

Transient Voltage

Surge

Suppression

(TVSS) and

EMI/RFI Filters

Provide surge protection. Filter electromagnetic interference (EMI) and radio frequency interference (RFI).

Minimize any surges or interference present in the utility line and protect the sensitive equipment even when on

internal bypass power.

Rectifier/Power

Factor

Correction (PFC)

Circuit

In normaloperation, converts utility AC 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

ensures efficient use of utility power and reduces distortion reflected on the utility making cleaner power

available to devices that are not protected by the UPS.

Inverter

In normaloperation, inverts the DC output of the power-factor-correction circuit into precise, regulated sine-

wave AC power. When utility power fails, the inverter receives energy from the batteries through the rectifier. In

both Normal mode and Bypass mode, the UPS inverter remains on-line, generating clean, precise, regulated AC-

output power.

DC-DC Charger When the UPS is connected to utility power and the rectifier is operating, the battery charger regulates energy

output from the rectifier/PFC to continuously recharge the batteries.

Static Bypass

Switch

In the event of an output overload, over-temperature condition, or other failure, the switch automatically

transfers connected equipment to bypass power.

Batteries

Up to 4 strings of long-life, valve-regulated, non-spillable, lead-acid batteries depending on back-up run-time

requirements. See Table 7.3 on page55, for approximate run times.

NOTE: To maintain battery design life, operate the UPS in an ambient temperature of 68°F to 77°F (20°C

to 25°C).

Maintenance

Bypass Breaker electrically isolates the UPS and internal batteries for maintenance.
