2.2 Installation (unit: mm)

This series of products should be installed in a dry and dust free environment, and avoid

exposing to excessive heat, radiation and high electrical noise source. The meters can be

installed into a standard panel cutout of switch cabinet.

A. Remove the clips from the meter and insert the meter into the cutout from the front side.

Make sure that the screen is at the front of the panel.

B. Install clips on the back side of the meter and secures tightly to ensure the meter is

affixed to the panel.

2.4 Wiring

2.4.1 Voltage, current, input terminal wiring instruction

A Three-phase four-wire connection (3LN, 3CT)

The 3-Phase 4-Line wiring mode is commonly used in low voltage electric distribution power

systems. The UL(voltage wiring mode) parameter should be set as 3Ln, the IL(current

wiring mode) parameter should be set as 3C at the parameter setting interface.

B Three-Phase Three-Line open Delta Mode (2LL, 2CT)

2PT open delta wiring mode is often used in high voltage systems. For this mode, the UL

(the voltage wiring mode) should be set as “2LL”, and the IL (the current wiring mode)

should be set as “2C” at the parameter setting interface.

2.4.2 Power supply, communication interface, and Digital input

A. Power Supply

The power supply for this meter is AC 85-265V (45-55Hz) or DC 85-300V. Terminals for the

power supply are (L/+,N/-). The typical power supply wiring is as followed:

If the quality of power is poor or there is an EMI problem, it’s recommended to equip an

EMC filter in the auxiliary power supply loop. The mode of wiring is as followed.

B. Communication Interface

This meter support RS485 serial communication and the ModbusRTU protocol. Terminals

for wiring are 485A, 485B. The transmission medium of RS485 is shielded twisted pair

(STP). And the RS485 interfaces also can be used to the devices maintenance and

upgrading.

C. Energy Pulse Output Wiring Mode

Energy Pulse Output (Pulse Constant is 9600):

The terminal PE-/PE+ are used for active energy pulse output.

D. Digital Input

Digital Input (Extension function): wiring mode as shown below, the actual number of digital

input depends on the actual energy meter model.

Chapter 3 Meter Display and Basic Operation

There are four buttons on the front panel, labeled H, P, E and V/A from left to right. It can

be used for displaying different measuring data and setting parameters though the four

buttons.

Introduction: Perform the following button operation, the meter displays the measured

parameters. Different module of energy meters have different display items, even some

items won’t be displayed.

Therefore, the user should operate according to the specific conditions of the energy meters

during use.

3.1 Parameters Display

(1) Phase Voltage, Line Voltage and Current

Press button “V/A”, it will display the values of phase voltage, line voltage and current

circularly.

(2) Press button “E”, it will display the values of energy parameters circularly.

Total Active Energy Total Reactive Energy

(3) Press button “P”, it will display the values of power parameters circularly.

(4) Press button “H”, it will display the total harmonic distortion(THD) of voltage or current

circularly.

Press “H” or“E” , the meter will display the 2nd~31th HC(harmonic content). The harmonic

order will increase from 2nd to 31st by one each time P is pressed. And the harmonic order

will decrease by one each time E is pressed. And press “H” or“E”again, it will the parameter

display interface of voltage & current.

3.2 Parameters Setting Operation

3.2.1 System Parameter Setting

Press “H” and “V/A” simultaneously at any display interface of metering data, it will enter

the system setting interface.

At the setting mode:

The button “H” is used for digital shift. It can edit one digit shift left each time, and the digit

will be flashing.

The button “P” is used to plus 1, i.e., the flashing digit will be plus 1 when pressing "P"

each time.

If the flashing digit is 9, then press "P" and the digit will become 0.

The button "E" is used to minus 1, i.e., the flashing digit will minus 1 when pressing "E"

each time. If the flashing digit is 0, then press "E" and the digit will become 9.

The button “V/A” is used to confirm the setting and turn to the next setting interface.

If press “H” and “V/A” simultaneously at any setting interface, it will quit the setting

interface and turn to the display interface of metering data.

Password Inquiry

(1) Press “H” and “V/A” simultaneously at any display interface of metering data, it will enter

password setting interface. The default password is 0000. If the password is not co rrect,

press button“V/A”, the meter will be still in the password inquiry page, and an alarm icon (

) will flash in the lower-left corner. If the password is correct, it will enter the next setting

interface.

Password Input Interfaces

(2) Back-light Time Setting

”BL” interface is the page of backlight time setting. At this page, the user can see and set

the backlight time, the setting range is 1-999. After the setting, press ”V/A” to confirm and enter the next setting

interface.

Back-light Time Setting

(3) Meter ID Setting

At this page the user can see and set the address of meter, the range is 1-247, after setting,

press ”V/A” to confirm and enter the next setting interface.

Meter ID Setting

(4) Communication Parameters Setting

”CM ” interface is used for setting the RS485 communication parameters.

The default communication parameter setting is 9600-n81.

The baud rate can be set as 9600, 4800, 2400.
