1. Summary
1.1 Introduction The Hypertec Uninterruptible Power Supply (UPS) provides uninterrupted,
high quality, efficient and reliable AC power to loads It also has functions for protection and monitoring of the UPS operation.
This series of 1KVA-3KVA products are designed as advanced ON-LINE
UPS that provide the multiple functions and good performance.
1.2 functions and characteristics
1.2.1 Digital Control Technology: Utilising high efficiency and high reliability controller algorithm design are used to optimize the output parameters of the UPS.
1.2.2 Self-Test diagnosis: A self test occurs before starting to find potential problems with the UPS to avoid any downtime.
1.2.3 Double conversion on-line topology: Makes the output of the UPS a Pure Sine Wave with consistent frequency and voltage. Other benefits are low noise and no interruption because of the main power fluctuation, hence providing more comprehensive protection for the attached equipment.
1.2.4 Intelligent function without surveillance: Output power is supplied automatically from the batteries when main power has failed. There is no transfer time when switching the output of the UPS when the main power fails or restores.
1.2.5 Bypass function: When the UPS meets a fault, it can transfer to bypass with no interruption to supply power to loads and provide alarm.
1.2.6 Advanced voltage compensation technology: This makes the input voltage range from 115v to 295v which reduces the battery usage and enhances the adaptive ability against inconsistent line power variation.
1.2.7 Advanced wide frequency input technology: The AC input frequency is 50Hz/60Hz making the input frequency range wider to allow load equipment of 60Hz specifications to be powered by the UPS. When the output frequency is 50Hz, the range of the AC input frequency is 45Hz-55Hz, When the output frequency is 60Hz, the range of the AC input frequency is 55Hz-65Hz.The UPS has good compatibility with a generator as the mains source and is suitable for different types of single-phase generators.
1.2.8 Advanced Power Factor Correction Technology (APFCT): With APFCT on the input of the UPS, the input power factor that can be achieved is greater than 0.98. It increases the power efficiency, removes the harmonic noise from UPS to utility and lowers the UPS operational cost. It really is an economical and environmentally friendly UPS.
1.2.9 ECO Function: This function can help you save electricity. When the input mains power is in a fixed range, the loads are supplied with power directly from the line source, while the inverter is on standby. If the input power becomes abnormal, the UPS will automatically transfer to backup to supply power to loads without
7
interruption.
1.2.10 Cold Start Capacity: When battery voltage is low, the UPS will protect itself and shut down automatically. When main power restores, the UPS will detect the main power and monitor it to determine whether the voltage and frequency are normal. If normal, UPS will turn on automatically to supply power to loads; if abnormal, UPS will start charger to charge the battery. The UPS will not turn on to supply power to loads until the voltage and frequency of the main power has been restored to normal conditions.
1.2.11 Emergency Start Function: When there is no main power, the UPS can be started by using a battery pack. It can meet the users’ emergency needs. The emergency start function is quite strong. In this scenario, the UPS can be started under a full load situation.
1.2.12 UPS Self - Protection Function: When the line power input/output voltage is too high or too low, overload, short-circuit, inverter temperature is too high, low voltage and overcharge of battery, network surge and so on, the UPS has inbuilt self protection mechanisms to prevent it being damaged.
1.2.13 Rack-Tower conversion LCD design. No matter what angle the display is to be viewed from, by simply pressing the key slightly can meet your perspective needs. The content displayed on the interface is rich. The capacity of the loads and the battery can be seen directly and the FLASH pictures and fan rotating icon can be displayed when charging. So it is easy to know it’s operation. When UPS fails, it can show the fault code, the machine can be maintained as soon as possible by inquiring fault code table.
1.2.14 The UPS can communicate with the computer using the included intelligent UPS monitoring software through either the USB or RS232 interface. All the parameters clearly displayed on the communication interface. The computer can control multiple functions of the UPS directly. With USB communication, the operation of the UPS can easily be monitored, even if the RS232 interface is occupied or connected at the same time. USB communications has priority.
1.2.15 Network monitoring: Via internal or an external SNMP adapter, UPS can go on the internet and provide the latest information and power messages. You can monitor and manage the UPS status through all kinds of network management systems.
1.2.16 In order to ensure the power of the important loads can last for a long time, you can plug the important loads into the second power down socket. When the battery voltage is below the predetermined value, only the first cut-off power socket is broken off, the second power down can keep on supplying power until the battery voltage reaches protect point and shut down.
1.2.17 Adopt international standard rack-mounted size. Whether you want to put it on the office desk or in the rack-mount as a system to manage, It can present your personal style with corresponding components.

LED indications on the front panel when in bypass mode are as follows:
The BYPASS yellow LED is on and the buzzer beeps once every 2 minutes. The warning red LED is also on when beeping. The exact load and battery capacity are displayed.
Changing to bypass mode occurs under the following two conditions:
Turn off the UPS in line mode while start the bypass output. Overload in line mode.
NOTE: When the UPS is in bypass mode, there is no backup in the case of a mains fault.
30
4.5.2 Line mode
LED indicators on front panel in line mode are as follows:
The inverter green LED is on.
When the input AC mains meets the conditions for normal operation, the UPS will work in line mode.
4.5.3 Battery mode
LED indicators on the front panel in battery mode are as follows:
Both the inverter green LED and battery yellow LED are on, the buzzer beeps once every 4 seconds. The warning red LED is also on when beeping.
When the input mains fails or fluctuates out of the range allowed by the UPS, the UPS will automatically change to battery mode. The UPS will alarm when battery voltage is low and the UPS will shutdown once it has reached its minimum threshold to protect the batteries. The time before shutdown when in battery mode is dependant upon the state of charge of the batteries and the load attached to the UPS.
4.5.4 ECO mode
LED indicators on the front panel when in ECO mode are as follows: Both the inverter green LED and bypass yellow LED are on.
When the input mains meets the input range of the ECO the UPS will begin ECO mode operation. If input mains exceeds the range of ECO several times in a row in a minute but stays in inverting input range, UPS will change back to inverting mode automatically.
4.5.5 Fault mode
LED indicators on the front panel when in fault mode are as follows:
31
Fault mode(Display interface on which the fault code displays)
The UPS goes into fault mode if an overload fault, inverting fault and/or over-temperature fault occurs. The UPS cuts off the output and fault codes will be displayed. At that moment, you can press the mute key to make the buzzer stop beeping temporarily to wait for maintenance. You can also press the ON/OFF key to shut down the UPS until confirmation that there is no serious fault. NOTE: For information regarding fault codes, please refer to Fault Code Information Table in section 7.2.
5. Maintenance Only minimum maintenance is required for this series of UPS. The battery is a sealed lead acid battery and is maintenance free. It only needs to be kept charged to obtain the expected lifetime. The battery charger operates regardless of whether or not the UPS has been turned on, so long as the input power cord is plugged into a working socket outlet. This automatically maintains the state of charge of the batteries and provide protection for over-charging and deep discharging.
5.1 Battery maintenance
o It is recommended that the batteries are manually discharged and then
charged at least once every three to four months if UPS has not been
used for a long time or the mains input source has not had an
interruption. The battery will need to be fully discharge to low-voltage
protection shutdown. This then needs to be fully charged.
o In high ambient temperature areas, batteries should be manually
charged and discharged once every two months. The process is the
same as that described above.
o Under normal operation, the battery working life is about three years. If
you find that the battery does not operate correctly and is shortening
32
the backup time or the battery voltage fluctuates, then the UPS
batteries should be checked, and possibly replaced, as soon as
possible. This must only be performed by qualified personnel.
o When replacing the batteries, it is recommended to change all the
batteries rather than changing the batteries individually on separate
occasions. Failing to do this, may result in permanent damage to your
charging circuit due to the variances in battery performance.
NOTICE：
Before replacing batteries, ensure to turn off the UPS and turn off or
disconnect the mains supply. Remove any metallic jewellery on your hands
such as rings, watch, bracelets and so on as a safety precaution.
When replace batteries, please use the screwdriver with insulating handle.
Do not lay the tools or metallic goods on the battery.
Never revert or short circuit between the battery anode and cathode.
