2. 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.
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-4324 series is AC +100V ~+240V.
2.1. Voltage Input
1. PM-4324 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.
2.2. Current Input1. The external CT’s are fragile, please handle with care.
2. The current input of PM-4324 series is in mArange.
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-4324 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-4324 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. ，Φ16～Φ24 use 200A CT，Φ24～Φ36 use 300A CT or 400A CT。
9. The maximum current value cannot exceed the CT rating.

2.3. Connection
PM-4324 Series
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-4324, 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).
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.

2.7. Add the Bias Resistor on RS-485 Network for stable signal
The RS-485 master is required to provide the bias for PM-4324 series.

ICP DAS Co., LTD PM-4324 Series Quick Start V1.3 Page 8
Otherwise, the tM-SG4 or SG-785 should be added to provide the bias. All
ICP DAS controllers and converters provide the bias.
