PM-3133 Quick Start
1. Shipping Package
This shipping package contains the following items
1 x PM-3133 module 1 x Quick Start Screw Driver x 1 CD x 1 Cable ties x 3
2. PM-3133 introduction
ICP DAS offers PM-3133 family in a full range of Single-phase and Three-phase smart power meters for power
monitoring. The products offer a rich feature set combined with easy-to-int egra te c ommunications.
With its high accuracy (<0.5%, PF=1), the PM-3133 series products can be applied both on low voltage primary
side and/or medium/high voltage secondary side and enable the users to obtain in real time the reliable and
accurate energy consumption readings from the monitored equipments while in operation. These compact size
and cost effective Power Meters are equipped with revolutionary wired clip-on CT (various types support input
current up to 200A) and standard Modbus communication RS-485 protocol for easy deployment. It works with
input voltages ranging 10V ~ 500V, supporting a wide range of applications.
2.1. Caution & Warning
The meter contains hazardous voltages, and should never be disassembled. Failing to follow
this practice will result in serious injury or death. Any work on or near energized meters,
meter sockets, or other metering equipment could induce a danger of electrical shock. It is
strongly recommended that all work should be performed only by qualified industrial
electricians and metering specialist. ICP DAS assumes no responsibility if your electrical installer does not follow
the appropriate national and local electrical codes.
ICP DAS assumes no liability for any damage resulting from the use of this product. ICP DAS reserves the right to

3.1.
Dimension: 127mm（length）× 33mm（wide）× 105mm（high）
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.
Reconfirm the RST (ABC) phase sequence of the power system.
PM-3133 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 for PM-3133 series is DC +12V ~+48V.
3.2. V oltage Input
1. PM-3133 series: Input Voltage up to 500V.
For any higher Input Voltage large than 500V, please add the PT (power transformer), and Change PT RATIO
setup.
2. Confirm the RST (ABC) phase sequence.
3.3. Current Input
1. The external CT’s are fragile, please handle with care.
2. The current input of PM-3133 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. The current input of PM-3133-xxxP series is in mV 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 or mA).
4. When more than one smart meter (PM-3133 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-3133 series) and its attached
split type clip-on CT are calibrated set by set. The mix use may cause wrong measurements.
5. 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)
6. 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.
7. Please handle with extra care, especially when the operation space of CT’s is limited.
8. The current direction must follo w K -L marked on CT’s.
9. 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
，Φ24～Φ36 use 300A or 400A CT。
10. The maximum current value cannot exceed the CT rating.

3.4. Connection
PM-3133
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-3133, 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).
3.5. 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 the CT and then close
the CT clip.
Installation steps finished.

5.2. Add the Bias Resistor on RS-485 Network for stable signal
The RS-485 master is required to provide the bias for PM-31xx series. Otherwise, the tM-SG4 or SG-785
should be added to provide the bias. All ICP DAS controllers and converters provide the bias.
