Applications
MPR-3 Series devices are microprocessor-baseddevices which are designed to measure all parameters
of an electrical network, calculate the consumption values and display these on its LCD screen. Events
like interruptions, time and settings changes, reset operations will be recorded in real-time thanks to its
internal flash memoryand Real Time Clock chip. These events then can be accessed and monitored
remotely via RS-485 line with Modbus RTU protocol.

INSTALLATION
The device has shunts for current measurement element there for it must be used with external current
transformers.If the device will be use with other analysers on the same panel ,it is recommented that the
device will be the last point on the current measurement line.
Device has 5 different connection configurations. These configurations are explained with diagrams
below:
3P4W (3 Phase with Neutral) Connection
For this configuration, four voltage connections (including neutral line) and three current connections are
used.Voltage inputs should be connected with 100 mA fuses as shown below.

11
3P3W (3 Phase without Neutral) Connection
For this configuration, three voltage connections and three current connections are used.
Aron without Neutral Connection
For this configuration, three voltage connections and two current connections are used.

12
3P4W BLN (3 Phase Balanced with
Neutral) Connection
For this configuration, four voltage connections and one current connection is used.
The device shows the same current value, which is measured from the first phase, for the unconnected
phases.
3P3W BLN (3 Phase Balanced without
Neutral) Connection
For this configuration, three voltage connections and one current connection is used.
The device shows the same current value, which is measured from the first phase, for the unconnected
phases.

13
Connection Test
After finishing device connections, you can check the connection that you’ve done by using the
automatic test function.
When you press the BACK button for 3 seconds, it switches to test mode. During this mode, at least 20%
of the nominal voltage must be applied to the voltage measuring inputs, at least 10% of the nominal
current must be applied to the current measuring inputs and the angle difference between current and
voltage inputs must be less than 30 degrees. These test conditions must be met.
During connection test, the device controls the connections and it can correct them internally or it can
leave the physical correction to the user.
If there’s an error between voltage inputs, it can only be corrected by changing physical connections.
If you encounter Error 12, make sure that all connections are done and minimum current/voltage values
are applied to the device.
On the following table, possible connection errors that maybe encountered during connection test and
their corresponding error codes that are displayed on the device screen.
Test Error Code
Test Code Description
0
All connections are correct
1
Phase-1 current direction is reversed
2
Phase-2 current direction is reversed
3
Phase-3 current direction is reversed
4
Phase-1 and Phase-2 voltage connections are reversed
5
Phase-1 and Phase-3 voltage connections are reversed
6
Phase-2 and Phase-3 voltage connections are reversed
7
Voltage connection phase sequence will be changed as L1,L2,L3 - L3,L1,L2.
8
Voltage connection phase sequence will be changed as L3,L2,L1 - L3,L1,L2.
9
CT-1, CT-2 will be swapped.
10
CT-1, CT-3 will be swapped.
11
CT-2, CT-3 will be swapped.
12
Test conditions are not met.
Line Termination Resistor
Line termination resistors are used when communication line length is longer than 10 metres. Usage of
accompanying line termination resistor between A and B terminals can enhance communication
performance in case of multiple devices on the same network.
