Chapter 1 Introduction
1.1 Product Introduction
IPM3400 series are designed for general single phase or poly phase power measurement, with wide
range. it con be applied either on low voltage primary side or medium/high voltage secondary side for
its high accuracy (<1%, IEC62053-21) under 5A current. IPM3400 equipped with clip-on CT, standard
communication, small size and low cost.
Features：
1. True RMS energy and power parameters measurement in compact size。
2. clip-on CT, easy wiring for on-line installation。
3. RS485 communication support Modbus protocol。
4. Wh accuracy better than 0.5%(pf =1)。
5. Support Lon Talks (option)。
6. wild range of measurement with various size of CT , up to 200A(24Φmm) 。
7. LED pulse output。
1.2 Caution
1.2.1 Danger
The meter contains hazardous voltages. The meter should never be disassembled. Failure
to observe this practice can result in serious injury or death. Any work on or near energized
meters, meter sockets, or other metering equipment can present a danger of electrical
shock. It is strongly recommended that all work should be performed only by qualified
industrial electricians and metering specialist. IA Networks assumes no responsibility if your
electrical installer does not follow the appropriate national and local electrical codes.
1.2.2 PRODUCT WARRANTY & CUSTOMER SUPPORT
IA Networks warrants all products free from defects in material and workmanship for a
period of one year from the date of shipping. During the warranty period, we will, at our
position, either repair any product that proves to be defective. To report any defect, please
contact ：[phone] or [email protected]w.
Please have the model, serial number and a detailed problem description available when
you call. If the problem concerns a particular reading, please have all meter readings
available. When returning any merchandise to IA Networks, a return SN. is required.
1.2.3 LIMITATION OF WARRANTY
This warranty does not apply to defects resulting from unauthorized modification, misuse,
or use for reason other than electrical power monitoring. The supplied meter is not a
user-serviceable product.

Chapter3: Installation
3.1 Inspection
On receipt of the instrument and prior to installation, makes sure it has not been damaged
during shipment.
The instrument is no longer safe when,
a) shows clear signs of damage
b) does not work
c) long storage under extreme conditions
d) damage during shipment
3.2 Safety
Please use the soft dry clothes to clean the instrument.
Please do not use any chemical or detergent or volatile solvents to clean the instrument, in order to
avoid any possibility of the cover damage。

Dimension of this product is 99mm（length）× 32mm（wide）× 78mm（high）
Products come with external split type clip on CT’s. Use only the attached CT’s, and do not
disconnect CT’s from meter. and never direct connect the other CT’s from the secondary side。
Please read this operation manual carefully before using。
Please re-confirm the measure position。
IPM3400 can be installed as rail mounting mode or embedded, no need to drill a hole or screw to
fix it（rail mounting width can up to the length of 35 mm ）。
Meter auxiliary power for IPM3400 is DC 10V -30V。
3.4 Mounting and Dismounting
3.4.1 Mounting
Pull down the “latch” of meter, and mount the meter on to the rail and lock it, as shown in below picture.
Pull down
3.4.2 Dismounting
Wire Disconnection
1. Open the clicked CT first and remove CTS from lines，Do not disconnect CT from
terminals.
2. Disconnect the voltage input wires from terminals and wrap the wire tips with plastic
tape.
3. Disconnect the communication wires from terminal.
4. Disconnect the Aux power from terminal and wrap the wire tip with plastic tape.
Dismount
From the back to pull down the latch, then can release the meter

Voltage Input
This instrument can measure voltage up to a maximum 300V. Higher than 300V, please
add the PT in front to protect the instrument.
Confirm the voltage.
Current Input
The external CT’s are friable, please handle with care.
The current input for this instrument is in mA range. Only the attached CT’s can be
used. The normal CT’s from panel will damage the instrument due to its large current
(around 5A)
When more than one instrument will be installed, please do not disconnect the CT with
its instrument. Each instrument is calibrated with matching CT’s.
To install CT’s, confirm the lines with terminals and latch on the split CT with each cable.
(Detail will be found in next section)
CT bending area is quite frangible; please handle with extra care, especially when the
room between CT’s is limited.
The current direction must follow K-L marked on CT
Please select the right size CT for different size current cables.
The maximum current value can not exceed the CT rating.

IPM3400
Please first check the current input terminal, and follow the white black, white black, white black, white
black wired order（1S 1L 2S 2L 3S 3L 4S 4L）.After connection the CT’s, clip on CT’s. Make sure the
arrow sign on CT’s follow current flow direction（K→L）Note: it must in same direction。
Connect the voltage input terminal. For IPM3400, connect V2- V2+ and V1- V1+。
Then, Connect RS485 D+ D- ，LonTalks D+ D- (”－”, ”＋” sequence base on the top cover mark
showed)。And then, add the auxiliary power。DC10- 30V (+ - FG)

Appendix：Question and Answer
Q1. if the turn point of the split type clip on CT break, or inner iron -core break, how to settle
this condition?
（1）the measure data will be not accuracy as before, and can not use again。
（2）please do not use the tape to fix it and then re-use again。
Q2. if multiple set of meter are being installed，the split type clip on CT and set of meter are able
to take it apart and to mix use？
Please do not mix use，because the set of ct and meter from IA Networks, are all calibrate well and
