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.
Meter auxiliary power is +85 ~ +264 VAC (277 VAC available).
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.

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 (W)→L(B).
Note: it must be in the same direction.
Connect the voltage input terminal N C BA. for PM-2133D, 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-2133D 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.
Current Input
1. The external CT’s are fragile, please handle with care.
2. The current input of PM-2133D 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-2133D 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-2133D 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 400A CT
9. The maximum current value cannot exceed the CT rating
