2. Installation
2.1.
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.
Meter auxiliary power for PM-3133i series is DC +12V ~+48V.

2.2.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.
2.3.Current Input
1. The external CT’s are fragile, please handle with care.
2. The CT input of PM-3133i-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).
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
，Φ24～Φ36 use 300A or 400A CT。
9. The maximum current value cannot exceed the CT rating.

2.4. 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.

3.2.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.
