1. Summary

1.1Introduction

UPS(uninterruptible power supply) is a kind of power supply

equipment that provides uninterruptible, high quality and efficient

and reliable AC power to the loads, it also has functions of protection

and monitoring. The UPS plays a very important role in power supply

of computer and its network, communication, finance, electricity,

transportation, national defense, college, scientific research

institutes and so on.

This series of RT 1250VA(S/H),RT 2000VA(S/H),RT 3000VA(S/H)

products are designed as advanced ON-LINE UPS that provide the

multiple functions and good performance.

1.2functions and characteristics

1.Advanced IGBT modules are used in our UPS. The electronic components

we used can work normally for more than 300,000 hours.

2.Digital control technology with high efficiency and the most

reliable controller algorithm design are used to optimize the output

parameters of the machine.

3.Self-diagnose before start. It can find potential problems of the

UPS in time to avoid any losses.

4.Double conversion on-line topology which makes the output of the

UPS a pure sine wave electricity with constant frequency and voltage,

low noise and no interruption of the main power fluctuation. It

provides more comprehensive and perfect protection for the users’

equipments.

5.No transfer time for the output of the UPS when the main power fails

or restores. It meets the high standard and high request of the precise

instruments.

6.The bypass function. When UPS meets a fault, it can transfer to

bypass with no interruption to supply power to loads and provide alarm.

7.Advanced voltage compensation technology. It makes the input

voltage range from 115v to 295v which reduces the battery usage and

enhances the adaptive ability against the bad main power variation.

8.The AC input frequency is 50Hz/60Hz. Advanced wide frequency input

technology makes the input frequency range wider.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 a good compatibility with generator. It is

suitable for different types of single-phase generators.

9.The advanced PFC( power factor correction)technology on the input

of the UPS makes the input power factor more than 0.98. It increases

the power efficiency, removes the harmonic noise from UPS to utility,

lowers the UPS operational cost. It’s really an economic

environmental protection power supply.

10.Intelligent function without surveillance. When main power is on

blackout, the UPS will start battery mode to supply power to loads.

When battery voltage is low, UPS will protect itself and shut down

automatically. When main power restores, UPS will detect main power

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 restore normally.

11.Cold start function. When there is no main power, UPS can be started

by battery pack. It can meet the users’ emergency needs. The cold

start function is quite strong. UPS can be cold started under the full

load situation.

12.UPS protection function:

When the main 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, UPS has a

protection function.

13.Rack-Tower conversion LCD design. No matter what angel to watch

the display, only press 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 saw 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.

14.The UPS can communicate with the computer with intelligent UPS

monitoring software through the RS232 interface. All the parameters

clearly display on the communication interface. Computer can control

multiple functions of the UPS directly.

15.Via internal or external SNMP adapter, UPS can go on internet and

provide the latest information and power messages. You can monitor

and manage the UPS status through all kinds of network management

system.

16.Convenient USB communication. You can see the operation of the

machine completely. Even if the RS232 interface is occupied or

connected at the same time, it will automatically switch to USB

connection.

17.ECO function can help you save electricity. When the input mains

power is in a fixed range, the loads is supplied with power by mains

power directly, the inverter is on waiting; when input mains power

is abnormal, it transfers to inverter to supply power to loads at once.

18.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.

19.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.

2. Safety instruction

Abstract

This chapter mainly introduce the safety marks and notes of RT

1250VA(S/H),RT 2000VA(S/H),RT 3000VA(S/H) series on-line UPS. Read

this chapter carefully before operating on the equipment.

2.1 Safety instruction

There is dangerous voltage and high temperature inside the UPS. During

the installation, operation and maintenance, please abide the local

safety instructions and relative laws, otherwise, it will result in

personnal injury or equipment damage. Safety instructions in this

manual act as a supplementary for the local safety instructions.

Our company will not assume the liability that caused by disobey of

safety instructions. Please note the following:

1. Don’t use the UPS when the actual load exceeds the rated load.

2. There are high-capacity batteries in the standare type UPS. You

mustn’t open the enclosure or it will lead to electric shock. If

it needs internal maintenance or battery replacement, please send

it to the designated site.

3. Internal short-circuit of the UPS will cause electric shock or fire.

So don’t place the containers equipped with liquid on the top of

the UPS so as not to cause danger of electric shock and so on.

4. Don’t put the UPS in a place with high temperature or humidity as

well as the corrosive gas, much dust.

5. Keep good air circulation between in-vent on front panel and

out-vent on back panel.

6. Avoid direct sunlight or near heat-dispensed objects.

7. In case that the smoke appears on the UPS, please cut off the power

as soon as possible and contact the dealer service site.

4. Installation

4.1 Unpacking and inspection

1. Unpacking the UPS and check that whether it’s damaged during the

transportation. If damaged or some parts missing, don’t start the

machine and inform the carrier and franchiser.

2. Check the annex (please consult Appendix Table 1).

3. Check if the equipment is just what you wanted to purchase. You

can affirm through inspecting the model number on back panel of

the equipment.

4.2 Notes

1. Please place the UPS in a clean, stable environment, avoid the

vibration, dust, too humidity, flammable gas and liquid,

corrosive.

2. The ambient temperature around UPS should keep in a range of 0℃～

40℃. If UPS works above 40℃, it is required that the rated value

of the largest load decreases 12％ while the temperature increases

the 5℃ every time. The highest temperature cannot be more than 50℃

when UPS works.

3. UPS should be placed in a sufficiently ventilated place.

4.3 UPS input connection

Connect the UPS to the mains by input power cable which is equipped

with the UPS.
