Safety instruction

Transporting

1. Disconnect all power cables if necessary.
2. Be carefully 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).

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℃

Installation

1. The UPS must be connected to distribution box which have the earthed shockproof and the protection against electric current.
2. Do not connect the secondary power equipment in distribution box to the UPS.

Operation

1. 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.
2. Ensure that no fluids or other foreign objects can enter the UPS system.

Maintenance and service

1. Caution – risk of electric shock.
   Even after the UPS is disconnected from the mains power supply, 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 voltage is present.

2. Only persons adequately familiar with UPS and with the required precautionary measures may exchange batteries and supervise operations.
   Any unauthorized persons do not open cover for maintenance.

3. The UPS with high voltage may cause electric shock and have a high short-circuit current. Please take the precautionary measures specified below and any other measures necessary when maintenance the UPS:
   – remove wristwatches, rings and other metal objects
   – use only tools with insulated tools and insulated gloves.

UPS description

DIN RAIL UPS ( LED , 500VA/1KVA)

1. Plug AC power: To indicate the AC power is applied to the UPS input ( AC output is available at this time). Green LED flashing, but without alarm sound (beep). Battery LED : Green LED flashing and the alarm sounds(beeps). The buzzer stops alarm sounds (beeps) after alarm sounds 7 times
2. Power (on): Press Power (on/off) button at least 3 seconds, the UPS will start up after two beeps and green LED lights up to finish startup procedure.
3. Power (off): Press Power (on/off) button at least 3 seconds under operation mode, the UPS will shut down after two beeps and put out the LED, then the LED light flashes to finish shutdown procedure.

Cable connection

Inspection

1. The UPS may be installed and wired only by qualified electricians in accordance with applicable safety regulations.
2. When installing the electrical wiring, please note the nominal amperage of your incoming feeder.
3. Inspect the packaging carton and its contents for damage. Please inform the supplier should you find signs of damage.

Connection

1. UPS input and output connection Connect AC input wires and wires of load to terminal block of the UPS. (About the terminal block, please refer to page 7)

UPS operation

Check prior to start up

1. Ensure the UPS is in a suitable positioning.
2. Check input cord is secured.
3. Make sure the load is disconnected or in the “OFF” position.
4. Check if input voltage meets the UPS rating required.

Operation procedure

Please follow the instructions below for the UPS operation.

1. Once the AC source is connected, the LED is flashing immediately to indicate charging (AC output exits). LED is blinking if the AC source is abnormal.
2. By pressing the Power (on/off) button at least 3 seconds until the buzzer beeps twice, the UPS will start up and LED lights up to finish startup procedure and the UPS is under Line mode.

Storage instruction

Disconnect input power in rear panel if you will not use it for long period. If the
UPS is stored over 3 months, please keep supplying power to the UPS for at least 24 hours to ensure battery fully recharged.

Trouble shooting guide

The following guideline may be helpful for basic problem solving

turn on the UPS successfully.
2| AC source is normal, but the UPS is overload up to 110%.
LED is flashing and alarm sound (beeps) once every 0.4 seconds. LED put out the light after 15
Seconds and the alarm sound (beeps) continuously.| Please reduce the load to <100%.
3| AC source is normal, but the UPS is overload up to 120%. LED put out the light and the alarm sounds (beeps) immediately.| Please reduce the load to <100%.
4| AC source fails. The load is supplied by battery power. LED is flashing once every 2 seconds and the alarm sound (beeps) once every 2.5 seconds. The alarm sound stops beeping after 7 times.| If AC source fails, reduce the load in order to extend backup time. If it is not abnormal power failure, please check the rated input voltage or connected line.
---|---|---
5| AC source fails. The UPS is under battery mode and battery power is approaching low level. The LED is flashing and buzzing once every 0.4 seconds.| The UPS will shut down automatically. Please save data soon.
6| AC source fails and battery runs out. The UPS has shut down automatically.| The UPS will restart up when AC source is restored. If AC source failure is more than 6 hours, please follow storage instruction.

Operation modes

UPS system block diagram

Normal operation

There are two main loops when AC power is normal: the AC loop and the battery charging loop. The AC output power comes from AC power input and passes through output replay to support power to load. The battery charging voltage comes from AC power input and converted by AC/DC charger to support battery- charging power.

AC source failure

The AC output comes from battery, passing through DC/AC inverter and static switch within the battery backup time.
