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.

1.5.1 Normal Mode
Normal operation supplies clean, conditioned, sine-wave power to connected equipment from normal
utility input. The battery charger charges the batteries. On the front-panel display, the run-indicator
(green)is On, the alarm indicator is OFF, and the buzzer is silent.

1.5.2 Battery Mode
Battery mode supplies battery power to the load if utility power fails or if the utility voltage goes outside of
the permissible range. On the front-panel display, the run indicator (green) is On, the alarm indicator
(yellow)is On, and the buzzer beeps once each second. The LCD "Current" screen displays "On Battery."

1.5.3 Bypass Mode
Bypass mode supplies power to the load from the bypass source if an overload or fault occurs during
normal operation. On the front-panel display, the run indicator (green) is On, the alarm indicator
(yellow)is On, and the buzzer beeps once each second. The LCD "Current" screen displays "On Bypass."

1.5.4 Auto Restart Mode
When enabled, which is the default setting, Auto Restart mode automatically re-starts the UPS after a
shut-down that resulted from depleted batteries after an extended power outage. A built-in 10-second
delay after utility power is restored allows other equipment to start first and stabilize before the UPS
restarts.

1.5.5 Eco Mode—Single UPS
The UPS ships in Eco mode as the factory-default setting. Eco mode reduces power consumption and
provides UPS efficiency approaching 99% 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 outside the specified range.
NOTE: During Eco mode, if a bypass-failure or abnormal-bypass-voltage notification appears when the
output is not overloaded, the UPS will transfer to Normal Mode. However, if a notification showing
bypass failure or abnormal bypass voltage appears when the output is overloaded, the UPS will shut
down the bypass.

1.5.6 Fault State
When the UPS is in Normal mode and the inverter fails or UPS over-temperature occurs, operation
transfers to Bypass mode. When the UPS is in Battery mode (with no bypass utility), and the inverter fails
or over-temperature occurs, the UPS shuts down and stops output power. During a Fault state, the front-
panel display alarm indicator (red)is On, the buzzer beeps continuously, and fault information displays on
the LCD screen.

1.5.7 Maintenance Bypass Mode
Used when the UPS requires maintenance or repair, Maintenance-bypass-mode operation powers the
connected equipment with utility power while electrically isolating the internal UPS components.
NOTICE
Risk of power interruption. Can damage the connected equipment.
If utility power fails or if its quality is out of range while the UPS is in Maintenance Bypass Mode,
the 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.
