6.1 Voltage input

The input voltage should not exceed 120% of the rated input voltage of the product (100V or 110V or 400V or 690V). Otherwise, the PT should be used; a 1A fuse must be installed on the voltage input; the wiring method of the product must be set according to the PT wiring of the product. The wiring method is as follows: Wiring method Selection

2 elements 3P3W

3 elements 3P4W

6.2 Current input

The standard rated input current is 1A or 5A. It requires the use of an external CT (recommended to use a wiring strip, not directly

connected to the CT, in order to facilitate disassembly); ensure that the input current corresponds to the voltage, the phase sequence is consistent and the direction is consistent; if There are other meters connected in the CT circuit used, the wiring should be connected in

series.Before removing the current input connection of the product, be sure to disconnect the CT primary circuit or short the secondary

circuit!

6.3 Communication Wiring

The meter provides asynchronous half-duplex RS485 communication interface, using MODBUS-RTU

protocol, various data information can be transmitted on the communication line. Theoretically, up to 128 power meters can be connected simultaneously on a single line. Communication

address of each power meter can be set. When wiring, keep communication lines away from power cables or other strong

electric-magnetic field

7.5.4 Voltage ratio setting refers to current ratio setting

For example: If the current input is connected by external CT and the rated value is 40A/5A, set the rated value of primary side

current to 40A, the scale value to 1, and the rated value of secondary current to 5A. Neutral current setting is the same. If the voltage

input is connected by external PT and the rated value is: 6000V/400V, then set the rated value of the primary voltage to 6000V, the

scale value to 1, and the rated value of secondary voltage to 400V. 7.5.5 Pulse constant setting (Only APM801 can be set)

When the pulse constant is set to 0, the default is 8000 when the rated value of the secondary side current is 1A, and the default

is 4000 when the rated value of the secondary side current is 5A. When the pulse constant is set to non-zero, the actual pulse constant

is the setted value*100. For example, if the set value is 50, the actual pulse constant is 5000.

Note: For high alarm types, the recovered value must be less than the alarm value. For low alarm types, the recovered value must be greater than the alarm value. The following is a schematic of how the meter handles alarm parameters.

Alarm description: The meter has two groups of alarms. Each group of alarms can detect a variety of alarm conditions, including changes in the

inputs of the electronic parameters, phase loss, reverse phase sequence, unbalance, and harmonics. The switch input and reverse phase

sequence only need to set the enable bit, and other alarms need to set the alarm condition. 7.5.7 Alarm Type Description

7.5.7.1 Electric parameter alarm

Overcurrent: Zero alarm setting does not apply to overcurrent alarm. When the single phase current is greater than or equal to the

action value and meets the set action delay time, the single phase overcurrent alarm starts; when the single phase current is lower than

the set recovered value and meets the delay time. The single phase overcurrent alarm is released. Undercurrent: When the single phase current is lower than or equal to the action value and meets the set action delay time, the

single phase undercurrent alarm starts; when the single phase current is greater than the recovered value and meets the delay time, the

single phase undercurrent alarm is released. Note: When undercurrent alarm and zero alarm is enabled, single phase current is equal to 0, the alarm is valid; when

undercurrent is enabled and zero alarm is forbidden, when single phase current is equal to 0, the alarm is invalid. 7.5.7.2 Phase current loss alarm When any current (not all current) is equal to or lower than the action value and meets the delay time, phase A current loss alarm

occurs; and when any of the following conditions occurs, the alarm is released: The three-phase current is greater than the recovered value and meets the delay time The three-phase current is lower than the phase loss action value. 7.5.7.3 Reverse phase sequence alarm: The values of action and recovery and delay time are not applicable to the reverse phase sequence alarm. When the phase

sequence is not ABC normal phase sequence, an inverse phase sequence alarm is generated. 7.5.7.4 DI alarm When the DI state changes from the initial state, an alarm is generated. Examples are as follows: Set Phase A overcurrent alarm of the first group of alarm enabled. Action value: The action value is a primary value. For example, if the alarm value is set to 5.500A, when Phase A current value exceeds 5.500A, the alarm condition is triggered and the timer starts. Action delay time: When the alarm condition is triggered, if Phase A current value exceeds 5.500A, an alarm record will be generated after the setted delay time (accurate to the second), Alarm group (alarm 1), alarm type (Phase A overcurrent), alarm time

(eg: 2017-5-12 14:15:20) will be recorded. If DO is associated with this alarm, the DO acts (see DO settings). Recovered value: The recovered value is a primary value. For example, if the recovered value is set to 5.400A, after Phase A

overcurrent alarm has occurred, when Phase A current value is lower than 5.400A, the released alarm condition is triggered and

the timer starts. . Recovered delay time: When the triggered alarm condition is released, if Phase A current value has been lower than 5.400A, the released alarm record will be generated after the setted delay time (accurate to second), and the alarm group (Alarm1), alarm

type (Phase A overcurrent), the released alarm time (eg 2017-5-12 14:17:20) will be recorded. If DO is associated with this alarm, the DO returns to its initial state. It can be calculated that the alarm duration is 2 minutes. Note: The alarm is invalid when both the action value and the recovered value are zero. 7.5.8 Demand setting

1. Press ◀▶ until you select dMd and press the Enter key. 2. Set the window time (Wid) (1, 2, 3, 5) and press the Enter key. 3. Set the demand period (Pd) (1-60), which must be set to an integral multiple of the sliding window time and press the Enter key. 4. Press the SET button to return.

Demand calculation method: APM series meters use the sliding window method to calculate the demand. In the sliding window calculation cycle, select a

calculation period (Period) and a sliding window (Width). The calculation cycle of sliding window must be divided equally. For example, three 5-minute sliding windows (Wid = 5, Pd = 15) are set in a 15 minute calculation cycle. Refresh the current demand at

the end of each sliding window. The schematic diagram is as follows:

subclass, press the Enter ke.Select whether to enable,press the Enter key. A DO can select multiple alarms for combined alarms. 2) If communication (COM) control is selected, modify the delay (DLY)time ranged 0-9999, unit 1 second. When it is set to 0, it is a

level control. When it is not 0, it is a pulse mode control,and it is disconnected after the delay time is set. 7. Press the SET button to return. Note:① When the output control mode of do1 is selected as ALM (ALM1 or ALM2), and is not associated (DISABLE)with

any alarm of ALM or associated with all alarms (ENABLE), When any alarm of this group (ALM1 or ALM2)is

generated , do1 will act. ② When the output control mode of do1 is selected as ALM (ALM1 or ALM2) and associated (ENABLE) with Phase A

overcurrent alarm and Phase A overpower alarm and not associated (DISABLE) with the other alarms. After the

setting is completed, do1 acts when Phase A overcurrent or Phase A overpower alarm occurs. ③ Before selecting the alarm type associated with do, make sure that the alarm type is enabled in the alarm setting. If it

is not enabled, the do does not act when this alarm condition occurs. DO number

8.1 Ethernet Parameter Modification

8.1.1 Modification by Button Refer to 7.5 Network Settings of System Settings 8.1.2 Modification by Modbus Communication

Follow these steps to modify the Ethernet parameters: 1) Send the command 0xABCD to the register with the address 29 to enter the Ethernet setting mode; Send the command 0 to

the register with the address 29 to exit the Ethernet setting mode, and the modified parameters are not saved at this time. 2) The new value can be written to the register after entering the Ethernet setting mode. If the Ethernet mode is not entered, the modification is invalid. 3) Send the command 0XABCD to the the register with the address 37 to save the changes. After it is written successfully, the Ethernet module enters the restart mode. After the Ethernet module restarts successfully, the host can read the Ethernet

parameters correctly. 8.1.3 Modification by Web Pages Local network settings Firstly, enter the operating system (take win7 as an example), use the mouse to click on the network icon on the bottom right corner, click on "Open Network and Sharing Center", click on the change adapter settings, right-click the local connection, click

properties, double-click Internet Protocol Version 4 (TCP / IPv4 ), you will see the page shown below. Please follow the instructions, select "Use the following IP address", and fill in the IP address 192.168.1.110 (the same subnet), the subnet mask 255.255.255.0, the default gateway 192.168.1.1 (The DNS part can be left blank). Click OK on the page and click OK on the Local Area Connection Properties page to wait for system to complete configuration.

Connect the Ethernet module and the computer with a twisted-pair B cable, power the meter. If the local connection on the bottom right corner of the computer monitor is connected at this point, you can continue to the next step. Otherwise, power off the meter, check the network cable and network settings. WEB page configuration Open Internet Explorer, enter the Ethernet IP address in the address bar (http://192.168.1.150/, factory default setting), and the

Click Setup to enter the Ethernet & TCP/IP configuration interface, as shown below:

After the modification is completed, click Apply to wait for it to take effect. 8.2 Extension of RS485 Communication

Extended 485 communication does not support the DLT-645 protocol and only supports the Modbus-RTU protocol. 8.2.1 Extending RS485 Communication as a Modbus Slave Station When the second communication serves as a slave station, as the first channel RS485 communication, only supports the 0x03

command and does not support the 0x10 command. Refer to Chapter 8 for the address table. 8.2.2 Modbus TCP communication (Using ModScan software)

When using the Ethernet Modbus_TCP protocol, it supports 0x01 (read coil status), 0x02 (read input status), 03 (read hold

register), 0x05 (write single coil). (Note: When using the 01, 02, and 05 commands, they all correspond to the APM8xx meter's own

information. DI1 and DO1 correspond to the starting address 0.)

The contents of the following address table are for Modbus TCP operation only. (Related to the slave information read by the user)

Modbus-TCP/IP

1. General communication architecture

A communicating system over MODBUS TCP/IP may include different types of device: A MODBUS TCP/IP Client and Server devices connected to a TCP/IP network. The Interconnection devices like bridge, router or gateway for interconnection between

the TCP/IP network and a serial line sub-network which permit connections of MODBUS Serial

line Client and Server end devices.

Figure 1: MODBUS TCP/IP communication architecture）

The MODBUS protocol defines a simple Protocol Data Unit (PDU) independent of the

underlying communication layers. The mapping of MODBUS protocol on specific buses or

networks can introduce some additional fields on the Application Data Unit (ADU). The client that initiates a MODBUS transaction builds the MODBUS Application Data Unit. The function code indicates to the server which kind of action to perform.

Figure 2: General MODBUS frame

2. MODBUS On TCP/IP Application Data Unit

This section describes the encapsulation of a MODBUS request or response when it is

carried on a MODBUS TCP/IP network.

Figure 3:MODBUS request/response over TCP/IP

A dedicated header is used on TCP/IP to identify the MODBUS Application Data Unit. It is

called the MBAP header (MODBUS Application Protocol header)

Figure 4:The diffrences of modbus frame between Modbus TCP/IP and Modbus RTU

3. MBAP Header descriptio

The MBAP Header contains the following fields:
