1. INTRODUCTION

2. SAFTY INSTRUCTION

1.1 General Description

The continuity of electrical power is an essential requirement for critical load
operations .The Uninterruptible Power System (UPS) is designed to meet the
user‘s need of present computer, server and the equipment of office
automation that make the UPS more compact and less noisy.
To choose the UPS as your equipment protector is a wise investment
because it supplies reliable, pure and stable power at affordable price.

1.2 Key features

1. Multiple microprocessor and double-conversion design base.

2. Wide input range designed to operate under harsh environment.

3. High input power factor and DC-start function.

4. LED and LCD display for detail status and data; real-time alarm silence.

5. Enhanced protections against light, surges, and disturbance etc.

6. Remote monitoring with SNMP intelligent slot and RS-232 interface.

7. Light weight and compact size, easy to transport and place.

1.3 Important Notices

To be sure that the UPS will be operated correctly, the following items should
be noticed:

1. Read instructions carefully before operating the UPS.

2. UPS power connect instruction should be followed.

3. Please don‘t open the case to prevent danger.

4. If the UPS will be stored for long period, the battery must be charged once
every 90 days.

5. Retain the load within the rating of UPS to prevent faults.

6. Handle unusual events according to the trouble-shooting guide.

2.1 Transporting

1. Disconnect all power cables if necessary.

2. Be careful not to damage the UPS while transporting.

3. Don‘t move the UPS upside down.

4. Please transport the UPS system only in the original packaging (to protect
against shock and impact).

2.2 Positioning

1. Do not put the UPS on rugged or declined surface.

2. Do not install the UPS system near water or in damp environments.

3. Do not install the UPS system where it would be exposed to direct sunlight

or near heat.

4. Do not block off ventilation openings in the UPS system’s housing and don’t

leave objects on the top of the UPS.

5. Allow a minimum distance of 10 cm in the rear and two sides of the UPS for

ventilation.

6. Keep the UPS far away from heat emitting sources.

7. Do not expose it to corrosive gas.

8. Ambient temperature : 0 - 40

2.3 Installation

1. Connect the UPS system only to an earthed shockproof socket outlet.

2. Do not connect domestic appliances such as hair dryers or office equipment

which would overload the UPS system (e.g. laser printers) to UPS output
sockets.

3. Place cables in such a way that no one can step on or trip over them.

7. Keep the UPS clean and dry.

3. SYSTEM DESCRIPTION

1. Do not disconnect the mains cable on the UPS system or the building wiring
socket outlet during operations since this would cancel the protective
earthing of the UPS system and of all connected loads.

2. The UPS has its own internal power source (batteries). The output terminals
may be live even when the UPS is not connected to the AC supply.

3. Ensure that no fluids or other foreign objects can enter the UPS system.

2.5 Maintenance and Service

1. Caution - risk of electric shock.

Even after the unit is disconnected from the mains power supply (building
wiring socket outlet), components inside the UPS system are still connected
to the battery and are still electrically live and dangerous. Before carrying out
any kind of servicing and/or maintenance, disconnect the batteries and verify
that no current is present.

2. Only persons adequately familiar with batteries and with the required
precautionary measures may exchange batteries and supervise operations.
Unauthorised persons must be kept well away from the batteries.

3. Batteries may cause electric shock and have a high short-circuit current.

Please take the precautionary measures specified below and any other
measures necessary when working with batteries:

- remove wristwatches, rings and other metal objects

- use only tools with insulated grips and handles.

4. When changing batteries, install the same number and same type of
batteries.

5. Do not attempt to dispose of batteries by burning them. This could cause
battery explosion.

6. Do not open or destroy batteries. Escaping electrolyte can cause injury to
the skin and eyes.

1. Line LED (green): To indicate the AC power is applied to the UPS input.
In case this LED blinks, it means the main AC source is out of tolerance.

2. Bypass LED (yellow): To indicate the load is powered via the bypass.

3. Battery LED (yellow): To indicate the UPS is in battery backup mode
when the mains power has failed.

4. Inverter LED (green): To indicate the UPS is powered through inverter.

5~9. Load & Battery Capacity LEDs:

time to disable the buzzer.

(a) No. 5 to 8 LED is green color and No. 9 (used as warning LED for

overload or battery low) is yellow.

(b) These LEDs show the load % of the UPS if the mains power is

available (in normal operation). LEDs light up to indicate the following
information.

No. 5 LED: 0-35 % No. 5&6&7&8 LEDs: 76-95 %
No. 5&6 LEDs: 36-55 % No. 5&6&7&8&9 LEDs: 96-105%
No. 5&6&7 LEDs: 56-75 %

(c) In the battery operation, the LEDs indicate the capacity (%) of the

batteries. LEDs light up to indicate the following information.

No. 9 LED: 0%-25 % (battery low level)
No. 8&9LEDs: 26%-50 % No. 6&7&8&9 LEDs: 76%-95 %
No. 7&8&9 LEDs: 51%-75 % No. 5&6&7&8&9 LEDs: 96-100 %

10. Fault LED (red): To indicate the UPS is in fault condition because of
inverter shutdown or over-temperature

11. On/Test/Mute key: It should be pressed with the control key (see the
following item 12) simultaneously to do UPS auto test and turn off the
buzzer when in battery operation.

12. Control Key:

(a) When this key is pressed with the On/Test/Mute key simultaneously

for 3 seconds, the UPS will be switched on after two beeps.

(b) When UPS is in operation, press this key and On/Test/Mute/ key

simultaneously, the UPS will do auto battery test. And the Battery LED
will blink if the battery may have problem. Besides, in battery operation
(buzzer beeps), press this key and the On/Test/Mute key at the same

(c) When UPS is in operation this key is pressed with the Off key

simultaneously for 3 seconds, the UPS will be switched off after two
beeps

13. Off key: It should be pressed with the control key (see the above item 12)
simultaneously to switch off the UPS.
