3.3 Assembly
Close to the main body is module A, which is superimposed
into module B and module C in turn.
Disconnect all power to the meter and equipment that has the meter installed:
1)Disconnect the voltage by disconnecting the fuse on the voltage transformer (PT secondary) or by cutting off
the voltage isolation switch.
2)Short-circuit the secondary output of the current transformer (CT).
3)Disconnect the meter control power supply and any power supply to the module.
4)Confirm that the power has been disconnected using a voltage measuring device of the appropriate measuring
range.
3.4 Engineering Construction Precautions
3.4.1 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
3.4.2 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!
3.4.3 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
1. Insert the connection terminal into the module
2. Using a cable with a diameter of 0.2 to 0.3 mm, strip 6
mm from the end of each wire and connect it to the terminal
and insert the wire into the corresponding position of the
connection terminal.
3. The locking torque of the terminal screw is:
0.56~0.79N·m.

from power cables or other strong electric-magnetic field.
3.4.4 Supply voltage
The conventional power supply voltage of the instrument:AC/DC 85-265V;supply voltage with P2 funcion:AC/DC 115-415V.
3.5 Wiring method
According to different design requirements, it is recommended to add a fuse (BS88 2A gG) to the power supply and voltage input
terminals to meet the safety requirements of the relevant electrical specifications.
3.5.1 Main part

DIDO record
DIDO closes the record, the instrument body stores up to
128 DIDO event records (when the main record is full,
the new data covers the old data; if the expansion module
MLOG is configured, the data can be synchronized to the
TF card, when the TF card data is full The customer
needs to manually clear the data in the TF card and clear
the TF card data. For details, see the 11-fault
troubleshooting analysis. The MLOG indicator of the
expansion module is not flashing properly.)
alarm record
At the current Alarm 1, 2 state, the instrument main body
stores up to 16 recent alarm records, and 13 types of
alarm types are 128. When the main record is full, the
new data covers the old data; if the expansion module
MLOG is configured, the data can be synchronized to In

No TF Card ：No TF card, please refer to 11 failure
analysis for details.
TF Error：The TF card is damaged, and the data in the TF
cannot be written or read. For details, please refer to 11
Failure Analysis.
TF Full ：The TF card storage is full and needs to be
manually cleared by the customer. For details, please
refer to 11 Failure Analysis.
Check Ini File：The APM800Config.ini configuration file
in the TF card is incorrect. For details, see 11 Failure
Analysis. The TF card storage is full and needs to be
manually cleared by the customer. For details, please
refer to 11 Failure Analysis.
The normal working status of the TF card is as follows:
Free Size:TF card remaining storage capacity
Total Size：TF card total capacity
Xx recording events are being stored, and the meter
displays that the recorded data is being synchronized to
the TF card.

4.5 Interface Introduction
4.5.1 Main interface
The instrument is displayed as the instrument model and version information, and then the overview interface is
displayed. The default main interface of the instrument is the overview interface. The main interface can be set. For
details, refer to the default interface settings of 7.11 system settings.
4.5.2 Menu interface
The main interface press Menu to enter the menu interface.
4.5.3 Vector interface
The main interface press Menu to enter the menu interface. Press ∨until “Power Quality”is highlighted and
press √to display the power quality. Press ∨until “Vector”is highlighted and press √to display the vector.
Press < or > to switch the voltage sequence component and current sequence component. Press Menu to return to the
menu interface.

5.1 Viewing event records
5.1.1 View DIDO records
On the main screen, press Menu to enter the menu interface, press ∨until “Event Log”is highlighted, and
press √to display the event log. Press ∨until “DIDO Record”is highlighted, press √to display the DIDO
record. Event records can be generated when the DI/DO status changes, and the instrument body can store up to 128
event records. If the MLOG expansion module (including the TF card) is configured, all DIDO record data will be
automatically synchronized to the TF card for storage.
Note: The stored records are in the first-in, first-out principle. If the main body 128 records are full, the new
records cover the old records.
5.1.2 View alarm information
On the main screen, press Menu to enter the menu interface, press ∨until “Event Log”is highlighted, and
press √to display the event log. Press ∨until “Alarm Record”is highlighted, press √to view the current
alarm status; press > to view the alarm event record, press ∧or ∨to view the latest 16 alarm records in
chronological order; press > to view each alarm category record , press ∧or ∨to view the last 128 alarm records

Special symbol, this symbol
indicates that the alarm is on. If the
meter has an alarm, it has this alarm
symbol in the time bar. You need to
check the alarm type on this
interface. For other special symbols,
please refer to Note in the version
information in 7.13.
