2.2 Naming Rules

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

 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-4324 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 +100 ~ +240 VAC.

3.2.2 Mounting and Dismounting

 Mounting

Assembly: Place the PM-4324 on the DIN-Rail. Push the front of the PM-4324 toward the mounting surface until it audibly snaps into place. Dismantling: Pull out the latch and then remove the PM-4324 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.

 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.

3.2.3 CT’s installation steps

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-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).

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.

Current Input

1. The external CT’s are fragile, please handle with care.

2. The current input of PM-4324 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-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. 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

Definition of the floating format of the Bits

Value = (- 1)S x (1.M) x 2

S represents the sign bit where 1 is negative and 0 is positive E is the two’s complement exponent with an offset of 127.

i.e. an exponent of zero is represented by 127, an exponent of 1 by 128 etc.

M is the 23-bit normal mantissa. The highest bit is always 1 and,

therefore, is not stored.
