UNINTERRUPTIBLE POWER SUPPLIES-MTS 3-Phase Inversion Power Supply

1. Brief description Handbook Page 1 (1) Precautions:

1. Firstly, please connect ground wire of main input power supply to the terminal wiring bar marked by “G” on inverter.

2. When input and output switches are opened, there are voltages inside of the inverter,

non-professional technical personnel and the inverter may be hurt and damaged if they move or open the front door of the inverter.

3. When it is needed to replace fuses, please use fuses of same types and specifications.

4. Please install strictly according to requirements in handbook.

2. Installation and connection (1) Installation environment

Ensure following indoor environment for installation

1. Indoor temperature shall be appropriate

Inverter shall be capable of working in the indoor environment with temperature from 0℃-40℃.

When it starts, the temperature shall be higher than 0℃, and the ideal temperature is 25℃. The installation environment needs a good heat exhausting system, and the following is a feasible method. (1)Natural ventilation system;

It is only suitable for low-heat capacious area.

(2)Man-made ventilation system;

When enclosure temperature (TA) is higher than external temperature (TE), you shall install an air-conditioner. When the two temperatures are close to each other, the air drawing system capacity shall be greater. Calculate air flow according to following equation: Q(m3/h) = 3.1 + Pdiss (Kcal) / (ta-te) (c). The heat Pdiss released from all installed equipments are denoted by Kcal, you can increase Pdiss by 10% to reduce energy loss. (2) Check before installation

Open package, take inverter out, and check whether inverter is damaged during transportation. Open front door, check whether all switches are open, including:

1. Guarantee card

2. Handbook;

(3) Installation area

Ensure following aspects:

1. The distance between inverter back and walls, any other objects≥40CM;

2. Nothing is allowed to be placed on the top of inverter;

3. Sufficient examination spaces shall be provided for the areas before and above the inverte; 4. Power supply wires shall be induced from button or back of inverter.

(4) Connection

1. Before the inverter is connected to main input power supply and load equipments, please open all switches.

Attention: first of all, please connect ground wire of main input power supply to the terminal wiring bar marked by “G”. The inverter cannot work when it is not connected to “Ground” system.

After connecting all input/output wires, please check following: (1) Check polarities of DC input wires are correct;

(2) Check input/output wires are connected to terminal wiring bar of inverter correctly.

3. Operating procedure Handbook Page 3 (1) Start up

1. When DC input is normal, close DC input switch, to turn on inverter. 2. When inverter is normally turned on, close output switch; 3. Close load switch.

(2) Normal shut-off 1. Open load switch;

2. Open inverter output switch; 3. Open inverter DC input switch; 4. Open main input power supply. (3) Emergency shut-off

In cases of emergencies, shut off inverter in following steps: 1. Open main load switch;

2. Open inverter main input power supply;

(4) Trial running

When inverter starts up normally, all LED(OUT,BATT) indicator lights on back control panel are on, and the green LED(IN) indicator light flashes (the indicator light is indication of AC bypass input, the equipment is only an inverter, so the light is invalid).

4. Inverter fundamental diagram Handbook Page 4

(1) Normal operation

When input power supply is normal, power supply of inverter is normal. See diagram 3 直流输入开关输出开关静 逆变器逆止二极管态 开负载 Diagram 3

直流输入开关：DC input switch 逆止二极管：inversion diode 逆变器：inverter

静态开关：static switch 输出开关：output switch 负载：load

(1) CPU

Controls all operating conditions of inverter.

(2) Inverter

关 Inverter is an output component, which transforms DC voltage into stable AC Sine voltage. In

normal cases, the inverter output part is powered by inversion unit.

(3) Inverter shuts off

In normal conditions, with overload, inverter will be shut off, without output from inverter.

7. Alarm Handbook Page 5 (1) Alarm 1: DC low voltage

When the inverter starts, the buzzing will start immediately. After approximately 2 minutes,

the buzzing will stop automatically (setting as 5=ON); when DC voltage drops to below the

threshold low-voltage protection limit of inverter, the buzzing will restart (setting as 5=ON).

(2) Alarm2: output overload

The load power is greater than rated output power, that is to say, the percent is greater than

100%, if peak current of load is too great, the inverter will start alarming. When inverter starts alarming, you need reduce load capacity, otherwise, the inverter will be shut off automatically. (3) Alarm 3: overheat or fan faults

When control system and inverter power module of inverter are overheated by environmental

temperature or fan faults, the inverter will be shut off automatically.

8. Control panel functions (1) General explanations Inverter control panel:

1. LCD screen of 2 lines, 40 words in one line;

2. LED alarm indication:

On control panel are 4 indicator light: 3 are green, 1 is yellow. And the indicator lights corresponding to signal IN, OUT, BATT and BY will be on, flash or be off, to provide important information of inverter.

(1) Green LED (IN): industrial power supply input indicator light LED (IN) signal:

On – when input voltage and bypass voltage are normal;

Flash – when one voltage is abnormal (input voltage or bypass voltage), input voltage is abnormal.

(Note: invalid on this inverter)

(2) Green LED (OUT): inverter output indicator light LED (OUT) signal:

on – inverter works in inverter output status;

off – when inverter output overload or inverter output is transferred to bypass power supply. (3) Yellow LED (BY): bypass output indicator light LED (BY) signal:

on – when inverter output is transferred to bypass, inverter works in bypass status; off – when bypass is transferred to inverter output power supply.

(Note: invalid on this inverter) (4) Green LED (BATT): battery indicator light LED (BATT) signal:

On – when battery power supply or input voltage is lower than normal value; Off -- input voltage to recharge battery. 2．Emits alarming sound
