1. Introduction
Congratulations on your choice of the Always “On N Series On-Line Uninterruptible Power
System (UPS). The N Series features the very latest, top of the line, microprocessor technology
and IGBT transistors for clean, highly regulated, PWM (Pulse Width Modulated) True Sine
Wave power.
For ease of use, the N Series utilizes an LCD display to indicate “load percentage”, “battery
capacity”, input voltage, output voltage, input frequency, output frequency, internal UPS
temperature and the mode of operation. It also provides self-diagnostics, a combination
On/Alarm Silence/Manual Battery Test button, a combination Off/Bypass button, and two
levels of alarms when the unit is operating on battery.
The N Series incorporates an interface port for communications between the UPS and a LAN
server or other computer system with various operating systems installed. This port provides
detailed operating information including voltages, currents, and alarm status to the host system
when used in conjunction with the shutdown software. Also available are the optional SNMP
Adapter to permit remote control, monitoring and notification of UPS conditions via a network
or the internet, and an AS-400 interface to allow for relay communications in PLC or contact
environments.
1.1. Modes of Operation
The N Series UPS is designed to operate as a continuously on-line dual conversion
system in the following modes:
Normal - The critical AC load is continuously supplied by the UPS Inverter. The
input Rectifier derives power from a utility AC source and supplies power to the
Inverter while simultaneously float-charging the storage batteries.
Back-Up - Upon failure of utility AC power, the Inverter obtains power from the
batteries without interruption. There are no interruptions in power to the critical load
upon failure or restoration of the utility AC source.
Recharge - Upon restoration of utility AC power after an outage, the Rectifier will
automatically restart and supply power to the inverter and battery charger.
Automatic Restart - Upon restoration of utility AC power, after an extended outage
and complete battery discharge, the UPS will automatically restart and resume
supplying power to the critical load. Also the battery charger will automatically
recharge the batteries.
Static Bypass - The bypass will provide an alternate path for power to the critical
load and is capable of operating in the following manner:
Automatic - In the event of the inverter overload capacity being exceeded or
should an internal failure occur, the UPS will perform an automatic transfer of
the critical AC load from the inverter to the bypass source.
Manual - Should the UPS need to be taken out of service for limited
maintenance or repair, manual activation of the bypass will cause an immediate
transfer of the criticalAC load from the inverter to the bypass source. The input
rectifier, inverter, and battery charging operations will be inhibited until the user
transfers the UPS back to normal operation.

2. Product Description
2.1. Theory of Operation
The UPS (Uninterruptible Power Supply) is designed to be installed between utility
(commercial supplied power) and your loads. It is used to protect your loads from
noticing any power fluctuations (eg. Blackouts, brownouts, over-voltage conditions).
The UPS will supply a sufficient amount of steady, constant AC power during these
power fluctuations, allowing the loads to be shutdown properly preventing possible
damage to both hardware and software.

2.3. Description of Each Block
Input Breaker: Prevents the breaker of the distribution panel from tripping when a
UPS fault or over-current condition occurs.
EMI/RFI Filter: This filter attenuates the electrical noise associated with the
polluted utility power to the UPS or noise (THD) generated by the UPS.
Rectifier / Power Factor Correction (PFC): During normal operation, the
rectifier/power factor correction (PFC) circuit converts the utility power (AC power)
to DC power, which in turn is used by the inverter, while ensuring that the waveform
of the input current used by the UPS is close to ideal. This type of conversion and
technology maintains two key objectives: the utility power is used as efficiently as
possible, and the amount of distortion reflected back to the utility is minimized
therefore providing cleaner power to other devices in the building not being protected
by the N Series.
PFC Control: By utilizing control circuits, the current drawn from the utility
power is in-phase with the input voltage. The control circuit also allows the
UPS to have a broader input voltage range (±25%).
Charger: During normal operation, it converts AC voltage drawn from utility power
into regulated DC voltage, which charges or maintains the batteries at the desired
level by a float charge.
Batteries: Sizes will vary in series and series-parallel configurations. Batteries are
Sealed Lead-Acid Valve regulated gel cells.
DC-to-DC Converter: The converter utilizes energy from the battery system and
raises the DC voltage to the DC Bus operating voltage for the inverter. This allows
the inverter to operate continuously at its optimum efficiency and voltage, thus
increasing reliability.
Inverter: The term inverter will denote the solid-state equipment and controls used
to convert power from the input rectifier or batteries to regulated pure sine wave AC
power for supporting the loads. The inverter will produce 50 or 60Hz (auto-
selectable) using Insulated Gate Bipolar Transistors (IGBT’s) switching at
approximately 18kHz, above the audible frequency range, and without low frequency
magnetic components. The inverter is of pulse width modulated (PWM) design
capable of providing the specified AC output with a very small tolerance (±2%), with
little to no distortion.
CPU/Control/User Interface: The CPU controller monitors and maintains all
systems within the UPS while permitting communication between the UPS, user and
peripheral devices.
Static By-pass: A static transfer switch and bypass circuit is provided as an integral
part of the UPS. The inverter has an overload rating of 125% rated load for one
minute, 150% rated load for 20 seconds, 200% rated load for one and a half cycles.
The static bypass will auto transfer to bypass if these overload conditions are
exceeded. The static transfer switch control logic will contain an automatic transfer
control that senses the status of the inverter logic signals, and operating and alarm
conditions. This control circuit will provide an uninterrupted transfer of the load to a
normal input source (or alternate bypass source). Transfers are made when an
overload or malfunction occurs within the UPS, without exceeding the transient limits
specified herein.

2.4. Special Features
Efficiency Optimizer function
The Efficiency Optimizer function adds cost effectiveness, minimizes power loss and
reduces power consumption. Alternating between bypass and on-line modes is
achieved automatically and in accordance with the conditions of the utility AC power.
On-line mode may be used during times of intermittent power, and bypass mode
when the utility is within selectable parameters in order to obtain greatest efficiency.
Irregularities can be detected in less than a second, and on-line mode reactivated
immediately. Switching back to on-line mode occurs when input voltage is outside
±10% of nominal (± 15% selectable), when input frequency is outside of ±3Hz or
when no input utility is present.
Although high efficiency is standard, the default operation is in on-line mode. The
bypass can be activated in the LCD panel, though on-line can be run permanently if
preferred.
Free Run Mode
The UPS operates in free run mode when input frequency is outside of the selected
Input Frequency Setting (Chapter 6.5). Free run mode is when output frequency does
not match input frequency. When starting the UPS, the frequency regulation detected
is 50 or 60 Hz ±0.25Hz. Please refer to chapter 6.5 if you want bypass available while
running in free run mode.
Diagnostic tests
When you start the UPS, a diagnostic test is automatically executed that checks
electronics, battery, and reports any problems on the LCD display.
An advanced battery management system always monitors the conditions of the
batteries sending any forewarnings if replacement is needed. Otherwise every 30 days
of normal operation, a battery discharge test is performed and, if a problem arises it
will be reported on the LCD display.
Other than during the initial 24 hours, after startup, or while the UPS is in charging
mode, diagnostic tests (please see chapter 6.5) can be performed manually from the
front panel at any time.
