Installing the product
Accommodate the meter on the panel cutout and fasten it using the side locks
Ⓕ. Panel’s cutout dimensions must be 92x92mm.
Power Supply Connection
Power Supply signal must be applied to the Ⓖ terminal block. Ikron-03’s power
supply working range is 85…265Vac / 100…350Vdc (universal source).
Universal Power Supply
85…265Vac / 100…350Vdc (without polarity)
ATTENTION
Pay extreme attention to the type of auxiliary power supply of your meter.
Incorrect cabling connection or applying a voltage signal above the specified
limits can damage it severely.
Voltage Input Connections
Connect phases and neutral references to the Ⓗ inputs, using the order
described below:
| Terminal Description | Signal to be Connected |
|---|---|
| 18 – Va | ‘Phase’ R |
| 17 – Vb | ‘Phase’ S |
| 16 – Vc | ‘Phase’ T |
| 15 – N | Neutro |
Measurement Range: 20 to 500Vac Ph-Ph
11,54 to 288,67 Vac Ph-N
Current Input Connections
Connect phase references to the Ⓘ inputs, using the order described below:
| Terminal Description | Signal to be Connected |
|---|---|
| 23 – Ia* | CT’s S1 – Phase ‘R’ |
| 24 – Ia | CT’s S2 – Phase ‘R’ |
| 21 – Ib* | CT’s S1 – Phase ‘S’ |
| 22 – Ib | CT’s S2 – Phase ‘S’ |
| 19 – Ic* | CT’s S1 – Phase ‘T’ |
| 20 – Ic | CT’s S2 – Phase ‘T’ |
Measurement Range: 20mA to 5Aac (Continuous Overload: up to 6Aac)
Accessing Operation Modes
Instantaneous Measurements: checking of V, A, W, VAr, VA, PF and Hz values.
To access this mode, press the MENU key until the Inst message appears in the
display. To navigate through menus use RIGHT or LEFT ERROW keys.
Energy Measurements: checking of kWh+, kWh-, kVArh+, kVArh-, kW and kVA values. To access this mode, press the MENU key until the Ener message appears in the display. To navigate through menus use RIGHT or LEFT ERROW keys.
Function (Configurations): configuration of constants for PT and CT, connection diagrams, integration time (demand), communication parameters and reset command (energies and demands). To access this mode, hold the MENU key for three seconds.
Configuring the Product
The first step is to access Function mode, by holding the MENU until the
message FunC appears in L1. Then, to navigate through menus use RIGHT or LEFT
ERROW keys. To enter a specific menu, use the key.
PT Configuration: Definition of Potential Transformer ratio.
Example: 440/220V, PT= 0002.00.
Use key to navigate through the digits and RIGHT or LEFT ERROW to increment or
decrement the value of the active digit. If no PT is used, PT ratio must be
0001.00
CT Configuration: Definition of Current Transformer ratio.
Example: 500/5A, CT = 0100.00.
Use key to navigate through the digits and RIGHT or LEFT ERROW to increment or
decrement the value of the active digit. If no CT is used, CT ratio must be
0001.00
CD Configuration: Definition of Connection Diagram, according to the circuit
measured.
Use key to navigate through the
digits and RIGHT or LEFT ERROW to increment or decrement the value of the
active digit. Please refer to the “Connection Diagrams” table for checking the
available CD options.
To confirm a configured value, press until all digits stop flashing, only the
LEDs ‘k’ and ‘M’ will be blinking in this situation.

FAQ – Frequently Asked Questions
-
The iKron 03 doesn’t turn on
Check if the connection to the terminal block Ⓖ was made as stated in step ❸ and also if the voltage magnitude applied is within the working range for meter´s power supply. -
Measurement values seem incorrect
Check if voltage and current connections are corresponding to each other, i.e., each meter’s channel with the same reference indication – Example: (Va, Ia – Ia) – must receive signals from the same phase, as stated in steps ❹ and ❺. Also check if the polarity of CTs is correct (Correct Installing, Primary side: (LINE) P1 P2 (LOAD)| Secondary side, S1 connected to Ix S2 connected to Ix). Also verify if PT,CT and CD configurations are correct. -
Which parameter should be read to check energy consumption?
To read energy consumption info, the user must verify the Positive Active Energy parameter (EA). This parameter is the first that appears when Energy Measurements mode is accessed. “EA” is a cumulative value, so, to obtain the energy consumption during a period of time, a prior reading must be subtracted from the current value.
