NOTE

For the three-phase four-wire model, if the mains and bypass inputs use different power
sources, ensure that the neutral wires of the mains and bypass input power sources are
equipotential. For example, the mains and bypass inputs are from the same transformer.

Single UPS
The UPS uses a modular design. It uses multiple power modules connected in
parallel to deliver a high loading capacity. If one power module is faulty, other
power modules continue working. If loads are light, the UPS provides redundant
capacity even if only a single UPS is operating, which ensures high reliability.

Figure 2-2 Typical application scenario of a single UPS

Parallel System
In a parallel system, mains input, bypass input, and AC output terminals of UPSs
are connected in parallel. Energy control modules (ECMs) on different UPSs are
connected over parallel cables to synchronize UPS outputs to supply power to
loads. If one UPS fails, another UPS continues supplying power to loads, which
ensures system reliability.

Dual-Bus System
A typical dual-bus system consists of two independent UPS systems. Each UPS
system consists of one UPS or multiple UPSs connected in parallel. Of the two UPS
systems, one is the master system and the other is the slave system. The dual-bus
system is highly reliable and is suitable for loads with multiple input terminals. An
optional static transfer switch (STS) can be installed to start the bus
synchronization controller (BSC). The UPS systems work in inverter mode or
bypass mode.

NOTE

The Bus Sync Controller (BSC) mode refers to the bus synchronization control mode. For
downstream loads with a single power supply, the phases of multiple upstream power
supplies must be synchronized to ensure continuous power supply. The 2N, DR, and RR
architectures can be used to meet the requirements in different application scenarios. The
standard BSC mode can be selected for the 2N architecture. The BSC multi-bus mode can
be selected for the DR and RR architectures. The number of buses ranges from 3 to 5.

system is the master system, and other UPS systems are slave systems. Slave
systems automatically synchronize phases with the master system. The multi-bus
system is highly reliable and applies to loads with multiple input terminals. For
loads with a single power supply, a static transfer switch (STS) can be added to
supply power to the loads.

2.3 Working Principle and Modes

The UPS is an online product. It uses modular design, which facilitates
maintenance and capacity expansion. Intelligent control is adopted for modules.
The power module consists of a rectifier, inverter, and DC/DC converter. The
product converts inputs into pure high-quality sine wave outputs by using the
high-frequency switching technology.

UPS5000-H-1200 kVA
User Manual 2 Product Overview

Figure 2-6 Conceptual diagram

Table 2-3 Working modes

Mode Energy Flow Description

Normal In normal mode, the rectifier converts AC

mode power into DC power. Then the inverter
converts DC power into AC output. At the
same time, the rectifier charges batteries
over DC/DC. The conversions protect
loads from interference such as input
harmonics, glitches, and voltage
transients.

Bypass mode When the UPS detects that the power

module experiences overtemperature,
overload timeout, or other faults that
may shut down the inverter, the UPS
automatically transfers to bypass mode.
At the same time, the rectifier is started
and charges batteries over DC/DC. In
bypass mode, loads are powered by the
bypass module. The bypass power supply
is not protected by the UPS and therefore
is prone to the mains outage, abnormal
AC voltage waveform, or abnormal
frequency.

UPS5000-H-1200 kVA
User Manual 2 Product Overview

Mode Energy Flow Description

Battery mode If the utility power input is abnormal or

the rectifier becomes abnormal, the UPS
transfers to battery mode. The UPS
obtains DC power from batteries, and the
power is converted into AC output by the
inverter.

Source-share If the UPS works properly and the AC

mode input power of rectifiers is insufficient
(for example, the UPS input current is
limited due to low utility power voltage),
the UPS automatically transfers to
source-share mode. In this case, the UPS
obtains energy from both the utility
power and batteries, and the energy is
converted into AC outputs by the inverter.

User Manual 2 Product Overview

Mode Energy Flow Description

S-ECO mode Super economy control operation (S-ECO)

is a working mode that combines the
combines the advantages of high
efficiency in ECO mode and high
reliability in normal mode. In S-ECO
mode, the UPS preferentially supplies
power to loads directly through the
bypass and automatically determines
whether to compensate for load
harmonics based on load conditions to
achieve higher efficiency. It ensures
uninterruptible (0 ms) power supply and
reduces the impact of load harmonics on
the power grid.
NOTE
● Only the three-phase four-wire 380 V
AC/400 V AC/415 V AC (line voltage)
model supports the S-ECO mode.
● The system can work in S-ECO mode only
when the hardware of both the power
module and bypass module supports the
S-ECO mode.
● If the hardware of the existing power
module or bypass module does not
support the S-ECO mode, the ECO mode is
displayed (2–5 ms interruption may occur
during the transfer of this traditional ECO
mode). If the UPS works in S-ECO mode
but the hardware of the power module or
bypass module is changed and does not
support the S-ECO mode, a dialog box is
displayed, indicating that the hardware
does not support the S-ECO mode. After
you click OK, the UPS works in ECO mode.

ECO mode The ECO mode is an economical working

mode and needs to be manually set. In
ECO mode, when the bypass input is
within the ECO voltage and frequency
ranges and other ECO power supply
conditions are met, the UPS works in
bypass mode and the inverter is in
standby state. When the bypass source
voltage is outside the ECO voltage range,
the UPS transfers from bypass mode to
inverter mode. In either bypass mode or
inverter mode, the rectifier is started all
the time and charges batteries using
DC/DC. The ECO mode delivers a high
efficiency.

4.2.4 Recommended Circuit Breakers

● The input circuit breakers recommended are for reference only.
● The bypass input circuit breaker and downstream output circuit breaker
specifications are recommended based on the rated UPS capacity. If the UPS
needs to be overloaded, adjust the switch specifications based on the
overload current.
● The maintenance bypass circuit breaker is recommended based on the
scenario where a single UPS is used. In a parallel system, adjust the circuit
breaker specifications based on the total current.
● The UPS can generate large leakage currents. A circuit breaker equipped with
a residual current device (RCD) is not recommended.
● If multiple loads are connected, use recommended specifications for branch
circuit breakers.
● Select proper circuit breakers to protect loads and cables, and cascade them
properly to achieve selective protection.

380 V AC/400 V AC/415 V AC Voltage System

NOTE

The RS485_R DIP switch is used to enable a build-out resistor so that the ambient T/H
sensor can communicate with the controller. If there are no more than four ambient T/H
sensors on the bus, the RS485_R DIP switch does not need to be set. If there are more than
four, flip the RS485_R DIP switch of the ambient T/H sensor furthest from the UPS to ON.

● DIP switch settings on ambient T/H sensors

Each ambient T/H sensor has a unique DIP switch address, ranging from 32 to 44.
A DIP switch has six binary toggle switches. The bit on the leftmost is the most
significant bit, and the bit on the rightmost is the least significant bit. Bit 1
indicates ON, and bit 0 indicates OFF.

5.2.4 Mode Settings

5.2.4.1 Setting the S-ECO Mode

Prerequisites
● Only the three-phase four-wire 380 V AC/400 V AC/415 V AC (line voltage)
model supports the S-ECO mode.
● The system is working in inverter mode.

Context
● By default, the system works in a mode other than S-ECO. To enable the
system to work in S-ECO mode, set the working mode to S-ECO mode.
● In S-ECO mode, the bypass takes priority over the inverter in supplying power.
If the bypass fails, the UPS transfers to inverter mode.
● Both a single UPS and a parallel system support S-ECO mode which ensures
higher power supply efficiency.
● To avoid frequent transfers between S-ECO mode and normal mode, do not
set S-ECO mode when the bypass input is unstable or is sensitive to load
changes.
● When the load rate is less than 10%, the S-ECO mode does not present
obvious advantages so the S-ECO mode is not recommended.
● Before setting S-ECO mode, ensure that the bypass is working properly.
● In S-ECO mode, the UPS automatically selects the VFD, VI, or VFI working
mode in real time based on the combination of physical parameters such as
the load rate, load current THDi, load power factor, and real-time input
voltage waveform.
– S-ECO mode VFI: When the input voltage is of poor quality and fluctuates
greatly (the voltage and frequency exceed the specifications, the power

Issue 10 (2024-01-05) Copyright © Huawei Digital Power Technologies Co., Ltd. 235
UPS5000-H-1200 kVA
User Manual 5 Single UPS Commissioning

factor is less than 0.5, or the load rate is less than 10%), the UPS
automatically transfers to normal mode to avoid supplying power of poor
waveforms to loads. The UPS monitors the input voltage waveform in
real time. When the input voltage becomes normal, the UPS goes back to
the S-ECO mode or other power supply modes.
– S-ECO mode VFD: When the input voltage is of good quality and
fluctuates slightly and the load is mainly linear, the load current THDi is
less than the preset value (5% by default) and the power factor is greater
than 0.95. In this case, the UPS automatically enters the S-ECO mode
VFD, provides power supply at efficiency up to 99%, and achieves good
input current THDi. When the bypass input is disconnected or the voltage
is abnormal, the UPS continuously transfers to normal mode.
– S-ECO mode VI: When the input voltage is of good quality and fluctuates
slightly and the load is mainly non-linear, the load current THDi is greater
than the preset value (5% by default) and the power factor ranges from
0.5 to 0.95. In this case, the UPS automatically enters VI mode. The
inverter compensates for harmonics and reactive power of the load
current, which delivers the 98.5% efficiency together with a higher input
power factor and a lower input current THDi. When the bypass input is
disconnected or the voltage is abnormal, the UPS uninterruptedly
transfers to normal mode.
● The S-ECO mode requires the support of the hardware of both the power
module and bypass module. If the system runs in S-ECO mode but the
hardware is changed and does not support it, the system displays the
message "The current hardware does not support S-ECO. The system will
work in ECO mode." After you click OK, the system transfers to the ECO mode
(5 ms interruption may occur during the transfer to the ECO mode). If the
hardware supports this mode but the prerequisites are not met, the system
works in normal mode.

Procedure
Step 1 Set the mode. On the LCD, choose System Info > Settings > System Settings and
set Working mode to S-ECO. The information indicating that the UPS works in S-
ECO mode is displayed on the LCD.

Step 2 Set parameters.

NOTICE

● Ensure that the load power is stable. If the system load power fluctuation is
greater than the rated capacity of half a module (for example, the single-phase
load power fluctuation is greater than 16.67 kVA for a 100 kVA module), the
UPS may enter and exit from hibernation mode repeatedly.
● When the system is in peak shaving mode, the modules exit the hibernation
mode during the period of discharge for peak shaving.

Context
When the load power is small and stable, you can shut down the inverters in some
power modules so that these power modules enter the hibernation mode and
other power modules bear more load power. This improves the system efficiency
in the case of small load power and increases the power module service life. The
hibernation function can be set on the WebUI.

5.2.4.4 Setting the Peak Shaving Mode

Prerequisites
● The peak shaving mode is supported only when the UPS works in normal
mode and SmartLi batteries (lithium batteries developed by Huawei) are
connected.
● Before the system switches from normal mode to peak shaving mode, the
SOC value of lithium batteries must reach 100%.
● The system is working in normal mode.

Context
The peak shaving mode is used to reduce the use of mains power during peak
hours of the power grid or to reduce the OPEX. Peak shaving is implemented by
UPS source sharing between mains and batteries. During peak hours, the batteries
provide the preset output power, and the mains supplies the remaining part of
power to reduce the consumption of mains power. During off-peak hours, the
mains charges the batteries to reduce costs.

NOTICE

Currently, the peak shaving mode is supported only by the SmartLi 3.0 (short-term
backup power).

Procedure
Step 1 Choose System Info. > Settings > Peak Shaving on the LCD or Monitoring > UPS
System > Running Parameter > Peak Shaving on the WebUI, and set the

6.4 Commissioning the BSC Mode

The Bus Sync Controller (BSC) mode refers to the bus synchronization control
mode. For downstream loads with a single power supply, the phases of multiple
upstream power supplies must be synchronized to ensure continuous power
supply. The 2N, DR, and RR architectures can be used to meet the requirements in
different application scenarios. The standard BSC mode can be selected for the 2N
architecture. The BSC multi-bus mode can be selected for the DR and RR
architectures. The number of buses ranges from 3 to 5.

6.4.1 Commissioning a Dual-Bus System

NOTICE

● When the UPS works in S-ECO mode and BSC mode at the same time, if the
power supply is not synchronized, the UPS exits S-ECO mode and transfers to
inverter mode.
● In a dual-bus system, if one system is set to normal mode and the other system
is set to S-ECO mode, set the system in S-ECO mode to the master system.

Context
The dual-bus system consists of one master BSC system and one slave BSC system.
You can specify them (one UPS system cannot be set to both master and slave

6.4.2 Commissioning a Multi-Bus System

NOTICE

When the UPS works in S-ECO mode and BSC mode at the same time, if the
power supply is not synchronized, the UPS exits S-ECO mode and transfers to
inverter mode.

Context
A multi-bus system can be used in the DR or RR power supply architecture to
ensure high reliability. The multi-bus system consists of multiple independent UPS
systems. Each UPS system consists of one UPS or multiple UPSs connected in
parallel. One UPS system is the master system, and other UPS systems are slave
systems. The slave systems automatically synchronize data with the master
system. (Each system automatically competes for the master system so you do not
need to manually set the master or slave systems. However, a BSC system No.
needs to be set for each UPS system. The settings are complete during startup and
can be changed under the guidance of maintenance engineers.)

Procedure
Step 1 Connect BSC cables.

NOTICE

The BSC cable of the multi-bus system should be connected to the UPS with the
smallest ID in the parallel system. If the BSC cable is not connected to the UPS
with the smallest ID, an alarm will be generated, indicating that the BSC signal is
abnormal.

– The upper limit of the BSC system No. is 3 for a parallel system of six UPSs,
4 for a parallel system of five UPSs, or 5 for a parallel system of four or
fewer UPSs.
– If the BSC mode of a system is not set to multi-bus mode, the adjacent
systems that have been set to multi-bus mode will generate an alarm
indicating that the BSC signal is abnormal. The alarm will be cleared once
you set the multi-bus mode for the system.
– N BSC cables are configured for N buses. The length of each cable is
determined separately. The total length of communications cables must be
within 400 m.
– In multi-bus mode, if an adjacent system has a duplicate BSC system No.,
it will generate an alarm indicating that the BSC signal is abnormal. The
alarm will be cleared once you correct the BSC system No.
