6. Usage
6.1 schematic diagram

WIFI led indication, if you push the setting button last 5s, the WIFI led will flash 1s interval ,its means
meter enter into the status of waiting for WIFI distribution network . if WIFI led light on 5s , light off 0.1s ,it means
meter connect the WIFI successfully.
Impulse led indication: it will flash with different speed according the current load of the meter
Relay off signal : the signal display on LCD means relay switch off .
Down bond: you can push this button to check the different data display , it will reset the resettable
active energy to zero when you push this button last 5s ,but total active energy will not reset.
Setting button: if you push the setting button last 5s ,meter will enter into the status of waiting for WIFI
distribution network .if you want to reset status of WIFI distribution network, you also can push the setting button
last 5s.

Noting: for CT input type connection , the power consumed display in register is not fact power consumed. The
fact power= the power display in register of meterX CTrate. For example , the power display in the register is 0.5
kWh and the CT is 800/5 , the fact power consumed=0.5 kWh X 160=80kWh

6.2 Installation
The meter can be installed on a35 mmDIN rail
6.2.1The meter can not installed and used until it is checked goods and sealed before delivery
6.2.2The meter should be install in the water proof box indoor or outdoor . the meter's box should be fixed on
strong and flame-resistant wall with a recommended height of about1.8 m, where there is no corrosive gas
around .
6.2.3The meter should be install fully in accordance with connection diagram on the terminal cover, it is better to
use copper as the leading wire for connection. ll screws should be tightened.

7. Transportation and Storage
7.1 Heavy impact should be burdened to the products while transportation and unpacking.
7.2 The products should be stored in the original package and kept in place with temperature between-
40°+70°,the relative humidity less than 75% and no corrosive gas around .
7.3 Instorehouse , the meter should be placed on the shelf when kept in stock , there should not be more than 7
cartons piled up in vertical. Single-packed meters can not be piled up with more than 5 meters in vertical.
8. Warranty period
Within 12 months from the day of selling and provided that users operate correctly according to the requirement
of the user's manual , if the meter doesn't reach its technical specification. It can be repaired or replaced in free f

9.3 Energy meter register address
Note 1: one register address is store 2 byte data ,so the data length read as 4 byte when data number is 2 .
Note 2::you can use ID ID(0x00) to broadcast and got data when you do not know the meter ID. But this ways is
only for 1 pcs meter to connection on RS485 wire

. Meter input power
When the meter power on , you can push the setting button last 5s , meter enter into the status of waiting for
WIFI distribution network and the WIFI led will flash 1s interval .
its means meter enter into the status of waiting for WIFI distribution network . if WIFI led light on 5s , light off 0.1s
,it means meter connect the WIFI successfully.
. dd device
Please check firstly that your telephone have connected the available WIFI network , then click the add device
button .now the meter only used under 2.4GHz WIFI network , it can not use under 5GHz WIFI network .
Select the WIFI distribution network

Select the Plug
You can push the setting button last 5s , meter enter into the status of waiting for WIFI distribution network , then
click confirm button
Input the WIFI network account and password , then confirmed to next step

if WIFI led light on 5s , light off 0.1s ,it means meter connect the WIFI successfully.
Note: WIFI led status
1. flash1s interval : meter enter into the status of waiting for WIFI distribution network
2. light on 5s ,light off 0.5s : meter have connect the WIFI and login in cloud serve
PP Menu instruction
The meter will display online or offline after you add the device successfully .
You can click the device to check the meter detailed information
You will see the active energy data and remote control button and timing setting button in the menu

Control button : used for control on / off of meter output
Reset button: used for reset the total active energy to zero
Timing button: used for timing control on/off and time delay control on/off
1. time control :you can add the time which is control and which is control off ,if you do not select week , it will
save as single time control . if you select the week, it will save as cycle control .
2. time-delay control : you can set 1minute to 24hour max to time delay control. For example ,you can use
delay time control to control off theBatterycar charging after 2hours .
the meter do not have time clock internal ,the time control is decide to cloud serve, so make sure the meter
connect the available WIFI network.
3.Setting button : for protection value and unit price ,starting active energy value setting .
If you open prepayment function , you can purchase kWh energy and click save .

Then PP will write the balance kWh into the meter , when the meter balance value used up to zero. The meter
will cut off load automatic . when you closed the prepayment function . the meter will recover to normal function
using .
Voltage high limit(V): the overvoltage protection , it will cut off after high than this value.
Voltage low limit(V): the undervoltage protection , it will cut off after lower than this value.
The voltage high limit value must bigger than the Voltage low limit value .
Current high limit( ): the overload protection, it will cut off after high than this value.
For overvoltage/undervoltage/overload event , these status must last 3 s ,so the meter will cut off for
protection .it will delay 60s to confirm the voltage and current recover to normal status after cut off . it will switch
on automatically after confirmed the value recover to normal status.
Starting kWh value :this value is used for calculating the contrast active energy. If the user want to know the
power company meter have run how many after fixed time, you can input the current total active energy of the
power company in here ! for example ,the power company meter is display 50kWh, you can input the 50kWh in
the starting kWh value.
Meter price : how much price for each kWh
History kWh
It will show the last 7 days and 30 days total active energy consumption
nd total active energy cost .(only special order in some country)
Meter detail
It will show R.M.S value and bi-direction active energy and contrast active energy
Import active energy : it measure the total positive active energy
Export active energy : it measure the reverse active energy , such as solar power generation , reverse wire
connection , some power generator working .
Normally, the total active energy=| Import active energy | + | Export active energy |
Contrast active energy : it is used for contrast the kWh running with the power company meter or other kWh
meter .
R.M.S value all measure theCurrent instantaneous value
