Chapter 3 Installation

3.1 Inspection

The instrument is no longer safe when,

a) Shows clear signs of damage

b) Does not work

c) Long storage under extreme conditions

d) Damage during shipment

3.2 Safety

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.

3.2.1 Dimension and Latch

PM-3133-RCT User’s Manual v1.00 Last Revised: Mar. 2017 Page: 10

 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.

 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 is DC +12V ~+48V.

3.2.2 Mounting and Dismounting

 Mounting

Assembly: Place the PM-3133 on the DIN-Rail. Push the front of the PM-3133

toward the mounting surface until it audibly snaps into place.

Dismantling: Pull out the latch and then remove the PM-3133 from the DIN-rail.

 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.

PM-3133-RCT User’s Manual v1.00 Last Revised: Mar. 2017 Page: 12

3.2.3 Positional Accuracy

1. W Accuracy Better than 1% (PF=1; Input Current >50A; the “A” area).

2. Due to small variations in the winding density and coil cross-sectional area the

transducer output varies slightly depending on the position of the current within the coil

loop.

The diagram below shows the variation of accuracy throughout the coil. The variation is

greatest when the current is positioned near the junction of the connecting cable and the

coil, where there is some discontinuity, and the error here can be

typically 5%. Since in most applications the current is distributed

throughout a significant part of the area contained by the coil loop the

reading will be very close to the calibration value.

3.2.4 CT’s installation steps

Type

A

B

C

D

Accuracy 1% 3% 5% >5%

The current should not be positioned close to the

coil-cable junction (shown by the “D” area) since

the error for this region is greater.

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→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).

PM-3133-RCT User’s Manual v1.00 Last Revised: Mar. 2017 Page: 14

Voltage 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.

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. 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.

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 ＜Φ55 use 500A CT，Φ80 use 1000A CT，Φ105 use 300A CT.

9. The maximum current value cannot exceed the CT rating
