CHAPTER 1 - INTRODUCTION
The 3-Phase UPS system provides the critical load (such as communication and data processing
equipment) with high-quality, uninterruptible AC power. The power from the UPS is free from
voltage and frequency variations and disturbances experienced at the mains AC input supply.
This is achieved through high-frequency double-conversion. Pulse width modulation (PWM)
associated with Digital Signal Processing (DSP) control, which features high reliability
and convenience.
As shown in Fig.1-1, the AC input mains source is supplied at UPS input and converted into a DC
source. This DC source feeds the inverter that converts the DC source into a clean and input
independent AC source. The battery powers the load through the inverter in case of an AC input
mains power failure. The utility source can also power the load through the static bypass.
When the UPS system needs maintenance or repair, the load can be transferred to maintenance
bypass without interruption and the power module and bypass module can be removed for
maintenance.

CHAPTER 1 - INTRODUCTION
1.1.1 Dual-Feed Input
Fig. 1-1 illustrates the 3-Phase UPS in what is known as the Dual-Feed configuration. In this
configuration, the static bypass and maintenance bypass share the same independent bypass
power supply and connect to the power supply through a separate switch. Where a separated
power source is not available, the bypass and rectifier input supply connections are linked.
1.1.2 Static Transfer Switch
The circuit blocks (labeled Static Transfer Switch in Fig 1-1) contain electronically controlled
switching circuits that enable the critical load to be connected to either the inverter output or
to a bypass power source via the static bypass line. During normal system operation the load
is connected to the inverter; but in the event of a UPS overload or inverter failure, the load is
automatically transferred to the static bypass line. To provide a clean load transfer between
the inverter output and static bypass line, the inverter output and bypass supply must be fully
synchronized during normal operating conditions. This is achieved through the inverter control
electronics, which makes the inverter frequency track that of the static bypass supply, provided
that the bypass remains within an acceptable frequency window.
A manually controlled maintenance bypass supply is incorporated into the UPS design. It enables
the critical load to be powered from the utility (bypass) supply while the UPS is shut down for
routine maintenance.
INOTICE When the UPS is operating in bypass mode or on maintenance bypass, the
connected equipment is not protected from power failures or surges and sags.
1.1.3 N+1 Internal Redundancy
The 3-phase UPS system can be configured for internal redundancy. When configured, the UPS
system automatically becomes redundant if the load is at or below the capacity of the power
modules minus the capacity of one power module. Under normal conditions, all the power modules
in the UPS system share the load equally. If one or more power modules become unavailable and the
load is at or below the capacity of remaining power modules, the remaining power modules supply
the load instead of transferring to bypass.

CHAPTER 1 - INTRODUCTION
1.1.4 Parallel UPS Systems
INOTICE Two UPS systems in a parallel system must have the same battery
configuration. Each UPS system requires a separate battery cabinet.
A parallel UPS system with multiple UPSs can be installed to provide a parallel capacity and/
or redundant system. This load sharing system provides more capacity than a single UPS, and
can provide redundancy, depending on the load and configuration. In addition, when one UPS is
taken out of service for maintenance or is not operating properly, a redundant UPS continues to
supply uninterrupted power to the critical load. A built-in Controller Area Network (CAN) provides
connectivity for system metering and operational mode control.
1.1.5 Battery System
The external battery cabinet provides extended emergency short-term backup power for the
SM-20kVA and SM-40kVA UPS to enhance the usability and reliability of the systems. The external
battery cabinet ensures connected equipment remains operational during power events, providing
cost-eective, extended battery runtime. Two compatible external battery cabinets are available, the
BCT3L9N125 and BCT6L9N225 and are equipped with valve-regulated lead-acid (VRLA) batteries.
BCT3L9N125
• Contains two or three battery strings to be used with the SM-20kVA UPS.
• Up to two external battery cabinets with a total of four or six battery strings can be paralleled
together to extend the run time. The 2nd battery cabinet is optional.
I
NOTICE One battery string has two battery modules. The two battery modules
must put into two adjacent bays on same layer.
To configure a BCT3L9N125 battery system with four strings, use two BCT3L9N125s,
each with two strings.

CHAPTER 1 - INTRODUCTION
BCT6L9N225
• Contains four to six battery strings to be used with the SM-40kVA UPS.
• Up to two external battery cabinets with a total of eight to twelve battery strings can be
paralleled together to extend the run time. The 2nd battery cabinet is optional.
I
NOTICE One battery string has two battery modules. The two battery modules
must put into two adjacent bays on same layer.
To configure a BCT6L9N225 battery system with eight strings, use two
BCT6L9N225s, each with four strings.
The external battery cabinet is housed in a single free-standing cabinet with safety shields for
hazardous voltage protection. Up to two external battery cabinets per UPS may be used to meet
application runtime needs. The cabinets match the SM-UPS cabinet in style and color.
Hot-swappable battery module is designed for the external battery cabinet that reduced installation
time and maintenance time. A DC-rated circuit breaker within each cabinet provides protection and
servicing isolation.

CHAPTER 1 - INTRODUCTION
1.2 Operating Mode
This 3-phase UPS is an online, double-conversion, reverse-transfer UPS that operates in
these modes:
• Normal mode
• Battery Mode
• Auto-restart mode
• Bypass mode
• Maintenance mode (manual bypass)
• Parallel redundancy mode
• ECO Mode
1.2.1 Normal Mode
The UPS inverter power modules continuously supplies the critical AC load. The rectifier/charger
derives power from the AC mains input source and supplies DC power to the inverter while
simultaneously FLOAT or BOOST charging its associated backup battery.
Fig 1-3: UPS Power Flow in Normal Mode

CHAPTER 1 - INTRODUCTION
1.2.2 Battery Mode
Upon failure of the AC mains input power, the inverter power modules, which obtains power from
the battery, supplies the critical AC load. There is no interruption in power to the critical load upon
failure. After restoration of the AC mains input power, the “Normal Mode” operation will continue
automatically without the necessity of user intervention.
Fig 1-4: UPS Power Flow in Battery Mode
1.2.3 Auto-Restart Mode
The battery may become exhausted following an extended AC mains failure. The inverter shuts
down when the battery reaches the End of Discharge voltage (EOD). The UPS may be programmed
to Auto Recovery after EOD after a delay time if the AC mains recovery. This mode and any delay
time are programmed by the commissioning engineer.

CHAPTER 1 - INTRODUCTION
1.2.4 Bypass Mode
If the inverter overload capacity is exceeded when in normal mode, or if the inverter becomes
unavailable, the static transfer switch will perform a transfer of the load from the inverter to
the bypass source, with no interruption in power to the critical AC load. Should the inverter be
asynchronous with the bypass, the static switch will perform a transfer of the load from the inverter
to the bypass with power interruption to the load. This is to avoid large cross currents due to the
paralleling of unsynchronized AC sources. This interruption is programmable but typically set to be
less than 3/4 of an electrical cycle, e.g., less than 15ms (50Hz) or less than 12.5ms (60Hz).
Fig 1-5: UPS Power Flow in Bypass Mode
Fig 1-6: UPS Power Flow in Maintenance Mode
1.2.5 Maintenance Mode (Manual Bypass)
A manual bypass switch is available to ensure continuity of supply to the critical load when the UPS
becomes unavailable e.g. during a maintenance procedure.

CHAPTER 1 - INTRODUCTION
1.2.6 Parallel Redundancy Mode (System Expansion)
For higher capacity or higher reliability or both, the outputs of several 3-phase UPS systems can
be programmed for direct parallel while a built-in parallel controller in each UPS system ensures
automatic load sharing.
1.2.7 ECO Mode
To improve UPS eciency, the 3-phase UPS system works in bypass mode under normal operating
conditions and the inverter is on standby. When utility power fails, the UPS transfer to battery mode,
and the inverter powers the load. The ECO system eciency is up to 97.5%.
NOTE: There may be a short interruption (less than 10ms) during the transfer from ECO mode to
battery mode, but the loads will remain powered.
