1.4 Operating Principle
The operating principle of the UPS is shown in the figure 1-4.
Figure 1-4 UPS Operating Principle
1. The UPS is composed of mains input (main and bypass), rectifier/PFC, charger, inverter, bypass, battery, DSP
controller, single phase transformer, contactor and final output.
2. When the mains is normal, the rectifier will start, and the charger will charge the battery string. Before turning
on the UPS, the output voltage is bypass voltage, and the mains supplies power to the load through the bypass.
After turning on the UPS, the electronic transfer switch connects the inverter output to the load, and the mains
supplies DC power to the inverter through the rectifier/PFC circuit. The inverter then converts DC power into pure
sine wave AC power and supplies the AC power to the transformer connected to contactor. Final output is supplied
to load from transformer secondary through electronic transfer switch. Refer figure 1-3 for the position of contactor
and transformer.
3. When the mains is abnormal, the rectifier/PFC circuit boosts the battery voltage and supplies it to the inverter.
The inverter then converts it into pure sine wave AC power and supplies the AC power to the load through the
electronic transfer switch.
4. After the mains returns to normal state, the UPS will automatically transfer from Battery mode to Normal mode,
the mains supply DC power to the inverter through the rectifier/PFC circuit, and then the electronic transfer switch
supplies AC power to the load.

Vertiv|Liebert® S600 10kVA ~ 20kVA UPS | User Manual 15
1.5 UPS State and Operation Modes
The UPS state and operation mode include: Normal mode, Bypass mode, Battery Mode, ECO mode, Fault State mode
and Maintenance Bypass mode. The operation schematic diagrams of Normal mode, Bypass mode, Battery Mode and
Maintenance bypass mode are shown in Figure
1.5.1 Normal Mode
When the mains input is normal, the load is supplied with voltage-stabilizing and frequency-stabilizing power by the
mains after processing of the rectifier and the inverter, and meanwhile, the charger is charging the battery. The
operation mode is Normal mode.
In Normal mode, the run indicator (green) is on, the alarm indicator is off, and the buzzer is silent.
1.5.2 Bypass Mode
If the overload overtime, inverter or rectifier failure appears during the UPS operation in Normal mode, the UPS will
transfer to Bypass mode, that is, the load is powered by the bypass source, which comes directly from the mains input.
If the rectifier is normal, the internal charger will charge the battery.
In Bypass mode, the run indicator (green) is on, alarm indicator (yellow) is on, and the buzzer beeps every second. The
'Current' page in LCD will display 'On Bypass'.
1.5.3 Battery Mode
Upon mains failure or voltage out of range, the rectifier and internal charger will stop running, and the battery will
supply power to the load through the inverter. In Battery mode, the run indicator (green) is on, alarm indicator (yellow)
is on, and the buzzer beeps every second. The 'Current' page in LCD will display 'On Battery'.
1. The battery has been fully charged before delivery. However, transportation and storage will inevitably cause some
capacity loss. Therefore, it is required to charge the battery for eight hours before putting the UPS into operation for
the first time, to ensure the adequate backup time for battery.
2. The battery cold start can also be used to start the UPS from the Battery (charged) mode upon mains failure.
Therefore, the battery power can be used independently for improving the system availability to some extent.
1.5.4 ECO Mode (For Single UPS with External Battery Only)
In ECO Mode, the load is powered by bypass when the bypass voltage is normal, and the load is powered by inverter
when the bypass voltage is abnormal. ECO mode is an energy-saving operation mode. For power equipment
insensitive to power grid quality, you can use the ECO mode for power supply through bypass to reduce the power
loss.
1. In ECO mode, if the bypass failure or abnormal bypass voltage appears when the output is not overloaded, the UPS
will transfer to Normal mode. However, if the bypass failure or abnormal bypass voltage appears when the output is
overloaded, the UPS will not transfer to Normal mode, but shut down the bypass.
2. In ECO mode, the efficiency of the UPS is up to 94%.

Vertiv|Liebert® S600 10kVA ~ 20kVA UPS | User Manual 16
1.5.5 Fault State
In the normal mode, the UPS will transfer the load to Bypass mode in case of inverter failure or UPS
over-temperature. In Battery mode (with no bypass mains), the UPS will shut down and stop the output if the
inverter failure or UPS overtemperature appears. In UPS Fault State, the alarm indicator (red) will be solid on, the
buzzer will keep beeping, and the corresponding fault information will be displayed on LCD.
1.5.6 Maintenance Bypass Mode
If maintenance and repair for UPS are needed, you can switch the load to the Maintenance Bypass through
maintenance bypass MCB, and the power to the load is not interrupted. The maintenance bypass MCB is located at
the back of the UPS cabinet, and the capacity meets the requirements of total load capacities.
When the UPS has malfunctions, and can not working normally, please get in touch with the nearest Vertiv branch
office or local service center. It is prohibited to repaire the UPS by yourself, otherwise the personnel injury and
damage to the equipment will occur.

2.3.2 Environmental Requirement
UPS room The UPS is designed for indoor installation, which should be installed in a clean and well-ventilated
environment, to keep the ambient temperature within the specifications.
The internal fans provide forced air cooling for the UPS. Cooling air enters the UPS through the ventilation holes
on the front panel and exhausts the hot air through the back-ventilation holes. Therefore, do not obstruct the
ventilation holes. Maintain at least 200mm clearances between the front, rear of the UPS and the wall or adjacent
equipment (see Figure 2-2), to avoid obstructing the UPS ventilation and heat dissipation. Otherwise, the UPS
internal temperature will rise, which will shorten the UPS life.
If necessary, an indoor exhaust fan should be installed to keep the indoor temperature from rising. An air filter
should be used in a dusty environment where the UPS is to be operated.
