When you use series Multi-Channels Circuit Metering system, be sure to
carefully read this user manual, and be able to fully understand the implications, the
correct guidance of operations in accordance with user manual, which will help you make
better use this DC Energy Meter, and help to solve the various problems at the scene.
1. Before the meter turning on the power supply, be sure that the p ower supply within the
provisions of the instrument;
2.When installation, the current input terminal must non -open, voltage input terminals must
Non-short circuit;
3.Be sure the instrument wiring consistent with the internal system settings;
4.When c ommunicating with the PC, instrument communication parameters must be consistent
with the PC

1. - SUMMARIZE
monitoring of building electrical loads with a low installation cost-p er-point by combining sub-
metering. The unit performs real-time metering, measures energy consumption, multi-tariff time-
of-use (TOU) and monitors power quality of 4 channels circuits for three phase circuits.
Advanced communications options including Modbus via RS485, I/O communications provide for
extensive reliable data exchange. Multiple units can be connected together to meter unlimited
departmental metering applications within office towers, condominiums, apartment buildings,
shopping centers and other multi-user environments.
Measurement Function
Voltage: Line Voltage; Phase Voltage
Current: Total Current; Current per channel
Power and Power Factor: Total power Reactive Power, Apparent Power, Power Factor and for
per channel
Frequency: System Frequency
Energy Function
Energy (kWh) measurement meeting international standards, accuracy is Class 1.0. It optional
Time of Use feature: 12 Seasons, 4 Tariffs record, max three-month data for each channel.
Over/Under Limit Alarming
Users can select parameters and set their set points. An alarm will be triggered when the set
point is reached, user can get the info from MODBUS reading.
Power Quality Analysis
Optional power quality parameters such as voltage and current THD, Odd harmonic distortion
(Total Odd HD), even harmonic distortion (Total Even HD), 2 ~ 21 times the harmonic content,
Current K-factor (KF), crest factor (CF), telephone interference factor (THFF), voltage and current
unbalance etc.
Communication and Network
Supports RS485 communication open protocol: Modbus RTU;

3.- INSTALLATION AND START-UP
The manual you hold in your hands contains information andwarnings that the user
should respect in order to guarantee a properoperation of all the instrument
functions and keep its safetyconditions. The instrument must not be powered and
used until its definitive assemblyis on the cabinet’s door.
Whether the instrument is not used as manufacturer’s specifications, theprotection of the
instrument can be damaged.
When any protection failure is suspected to exist (for example, it presentsexternal visible
damages),the instrument must be immediately powered off. In thiscase contact a qualified
service representative.
3.1.- Installation
Mounting
Instrument is to be mounted on35mm Din-rail. Keep all connections inside the cabinet.
Note that with the instrument powered on, the terminals could be dangerous totouch and cover
opening actions or elements removal may allow accessingdangerous parts.Therefore, the
instrument must not be used until this is completely installed.
Notes:
Auxiliary power:
85-265VAC/DC power interface for standard products. Please ensure that the auxiliary power
match meter access to prevent damage to the product.

Voltage sampling 7.62mm 4pin
AUX sampling 5.08mm 2pin
Digital output terminal 5.08mm 3pin
RS485 COMM 3.81mm 3pin
The current input pin need to access the CT, and output signal of CT is 0-100mA or 0~0.333V, CT
access have polarity to power direction. Please confirm your ordering meter types and prepare
related CT.
Digital output is passive load, inside relay can drive max 250 VAC(3A)/30VDC(3A) load, please
make sure connected load do not exceed this capacity.
Wiring diagram may be changed due to the special requirements of customers’ order, please
refer the label on the rear part.

Note that with the instrument powered on, the terminals could be dangerous to touching and
cover opening actions or elements removal may allow accessing dangerous parts. This
instrument is factory-shipped at proper operation condition.
7. - MAINTENANCE
or repairing action should be done when the instrument open and powered on, should those
actions are essential, high-qualified operators must perform them.
Before any adjustment, replacement, maintenance or repairing operation is carried out; the
instrument must be disconnected from any power supply source.
When any protection failure is suspected to exist, the instrument must be immediately put out
of service. The instrument’s design allows a quick replacement incase of any failure.
