Three-phase four wire power supply：1) Power supply mode

This product uses three-phase four wire system power supply, power

supply, we must ensure that the normal power supply N and L1, in

order to make the equipment work normally, when L2, L3 any phase

power, do not affect the normal operation of the equipment.

2) Power supply voltage

Rated voltage of working voltage of this product：220VAC/380VAC；Operating error ：-20% ~ +20%；Allowable deviation：-6% ~ +2%；

3) Spare battery

The interrupt of power supply, can be maintained by the built-in

battery data concentrator and the clock, holding time of a month.

Power recovery, the preservation of the data is not lost, the normal

operation of the internal clock.

17


4) Power consumption

When the product in the non communication state, three-phase

power supply, the operating power is less than 3W, as the power is

less than 5va. When the communication state of concentrator

three-phase power supply, power is less than 6W, the apparent

power is less than 10va.

4. SIM card installation

SIM card slot in the concentrator side will have launched GPRS

services in the SIM card slot into the concentrator as shown, and

note that the SIM card insertion direction cannot be inserted. There

are external concentrator antenna location, concentrator through

GPRS communication, must be connected to the antenna.

18


5. Antenna installation

The side of the product is provided with an external antenna

interface.

Advice note:

The signal strength of the installation position should be confirmed

before antenna installation. The antenna should be placed in an open

position, and an external antenna is recommended.

In the use of electromagnetic shielding applications, should use

an external antenna, and the antenna should be placed in a

shielded area.

19


Long connecting line should be set into a ring and fixed to the

safety, the antenna is not too large angle.

Poor environmental signals (such as the basement, tunnel),

should contact the local operators to solve the problem of signal

coverage.

6. Connection of electric meter

This product through the RS-485 interface data acquisition of

three-phase digital ammeter, can measure power three-phase

voltage, current, power, power frequency power parameter, but

also has accumulated power, electric energy pulse, alarm, switch

input and output, analog quantity output and the loose network

communication function. The meter has a friendly man-machine

interface. Electric wiring diagram and wiring diagram as shown in

the concentrator:

20


Be careful： Voltage input ：When direct input, the rated input voltage input

voltage should be not higher than the meter (400V), you should

consider the use of voltage transformer (PT). 1A fuses must be

installed at the voltage input.

Current input: Standard rated current is 5A, when the input

current is more than 5A, you must use the external current

transformer (CT).

To ensure that the input voltage, input current corresponding to

the same order, the line and the direction of the line is

consistent, otherwise there will be a number of measurements

21


and symbol error.

The electric meter input connection mode according to the

number of the current mutual inductor, in the case of external 2

current transformers, select three-phase three wire connection

mode. In the case of external 3 current transformers, select the

three-phase four wire connection mode.

The specific use of electricity meters, please refer to the

instructions for the use of electricity meters.

五、 Installation and debugging

1. Matters needing attention

Be careful： Please operate strictly in accordance with the relevant provisions

of the electricity sector;

No power leads off the concentrator charged in the case, in order

22


to avoid danger;

The installation site should take careful safety measures to

prevent personnel from electric shock;

Please make sure that you have read the instructions carefully

before the operation;

2. Construction preparation

1. In the installation of concentrator before at least need to install a

fixed IP address of the cloud server and can run normally. In order

to speed up the progress of the installation and configuration of IP

and the port number of the concentrator best done in the office.

2. Prepare a SIM GPRS card, in order to connect to the use of the cloud

server.

3. To prepare all kinds of wire, such as voltage wiring, current wiring,

RS-485 communication line, switch control line, Ethernet cable,

sensor access lines, etc.

23


3. Installation method
