1. Introduction
ICP DAS brings the most powerful, cost-effective, advanced Smart Power Meters PM-3 000
series that gives you access to real-time electric usage for single-phase power measurement.
With its high accuracy (<0.5% , PF=1 ), the PM-30 00 series can be applied to both low voltage
primary side and/o r medium/high volt age secondary side and enables the users to obtain
reliable and accurate energy consumption readings from the monitored equipment 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 200 A). It operates
over a wide input voltages range 10 ~ 300 VAC which allow s worldwide compatibility. And with
2 channels relay output, it can be linked with sirens or lightings for alarm messages. It also
supports Modbus R TU, Modbus TCP or CAN bus protocols for easy integration.
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

3. Installation
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.
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-311x series is DC +12V ~+48V or DC +10V ~ +30V (For PM- 311x-
xxxC).

3.2. Voltage Input
1. PM-311x series: Input Voltage up to 300V. For any higher Input Voltage large than 300V, please
add the PT (power transformer), and Change PT RATIO setup.
Notice: Please check the L‐N connection of PM‐311x‐xxxC series or it will cause the damage. Please refer
the following diagram.
3.3. Current Input
1. The external CT’s are fragile, please handle with care.
2. The current input of PM-311x 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 meters (PM-311x series) are installed, please do not disconnect the CT
with its original meter and mix us e with each other. Since each set of smart meter (PM- 311x 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. (De tail 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. Plea se 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 60 A CT，Φ10～Φ16 use 100A CT，Φ16～Φ24 use 200A CT
9. The maximum current value cannot exceed the CT rating.
