Chapter 1 Introduction
1.1. PM-3133i introduction
ICP DAS brings the most powerful, cost-effective, advanced Smart Power Meters PM-3133i
series that gives you access to real-time electric usage for three-phase power measurement.
With its high accuracy (<0.5%, PF=1 ), the PM-3133i series can be applied to both low
voltage primary side and/or medium/high voltage secondary side and enables the users to
obtain reliable and accurate energy consumption readings from the monitored equipments in
real time under operation. These compact size and cost-effective power meters are
equipped with revolutionary wired clip-on CT (various types, support input current up to 400
A). It operates over a wide input voltages range 10 ~ 600 VAC which allows worldwide
compatibility. Built-in AC isolator protection, this means total isolation between the AC
measurement side and the control side.
Application with Inverter:

Chapter 3 Installation
3.1 Inspection
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.
Products come with external split type clip-on CT’s. Disconnect the CT’s or use
other CT’s is highly prohibited.
Please read this operation manual carefully before using.
Please re-confirm the measure position.
PM-3133i series 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 is DC +12V ~+48V.

3.3.1 Mounting and Dismounting
Mounting
Assembly: Place the PM-3133i on the DIN-Rail. Push the front of the PM-3133i
toward the mounting surface until it audibly snaps into place.
Dismantling: Pull out the latch and then remove the PM-3133i from the DIN-rail.
Wire Disconnection
1. Open the CT clip to detach the CT, do not remove the CT terminal lines if
possible
Note: if you need to remove the terminal lines, always detach the CT before
removing the CT terminal lines. Otherwise the CT may develop open-circuit
secondary voltages which may be hazardous to personnel or damaging to the
CT or equipment connected in the secondary circuit.
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 auxiliary power from terminal and wrap the wire tip with plastic
tape.

3.3.2 CT’s installation steps
At the bottom of the CT, there is a
“K→L” mark.
Open the CT clip.
Make sure the power current
direction follow the “K→L” mark on

Chapter 4 Wiring Diagrams
4.1 Connection
Please firstly check the current input terminal, and then in white black, white black,
white black wire sequences (CT1-K, CT1-L, CT2-K, CT2-L,CT3-K,CT3-L). Then
connect the CT’s, and close the CT clip. Make sure the arrow direction sign on CT’s
follows current flow direction（K→L）
Note: it must be in the same direction.
Connect the voltage input terminal N C B A. for PM-3133i, in the three phase order
as follows on N C B A.
Attention please!! For 3P3W-2CT, connect in N C A phase sequence, do not
connect phase B (Check the diagram).

Voltage Input
1. PM-3133i series: Input Voltage up to 600V.
For any higher Input Voltage large than 600V, please add the PT (power transformer), and Change PT
RATIO setup.
2. Confirm the RST (ABC) phase sequence.
Current Input
1. The external CT’s are fragile, please handle with care.
2. The current input of PM-3133i series is in mA range. Only the ex-factory attached CT’s can be used.
The other CT’s, for example, from panel will damage the instrument due to its large current (around
5A)
3. When more than one smart meter (PM-3133i series) are installed, please do not disconnect the CT
with its original meter and mix use with each other. Since each set of smart meter (PM-3133i series)
and its attached split type clip-on CT are calibrated set by set. The mix use may cause wrong
measurements.
4. To install CT’s correctly, please ensure the CT lines sequences is right before clip the CT’s onto the
power cable of the monitoring equipment. (Detail will be found in next section)
5. When measuring the current, the secondary circuit of a CT should never be
opened when a load is passing through its primary. Make sure you always open
the CT clip to detach the CT before removing the terminal lines. Otherwise, it will cause severe
injury.
6. Please handle with extra care, especially when the operation space of CT’s is limited.
7. The current direction must follow K-L marked on CT’s.
8. Please select the right size CT’s for different size of monitoring equipment cables:
power cable diameter ＜Φ10 use 60A CT，Φ10～Φ16 use 100A CT，Φ16～Φ24 use 200A CT,
，Φ36 use 300A CT，Φ36 use 400ACT
9. The maximum current value cannot exceed the CT rating
