1. Make sure the positive wire is connected to pin 1 and the negative wire is connected to pin 2.

   Open

   

2. Make sure the power supply is 12 volts DC.

3. On the AC meter side, make sure the cable is not broken.

1. The AC meter's LEDs should be blinking and the power supply should be on.

2. Check that RS485 A and RS485 B cables are connected correctly (RS485 A = pin 14, RS485 B = pin 15).

3. Ensure the communication cables (RS-485) is in good condition and not broken or overly long (up to 15 meters).

4. Make sure the baud rate of the meter is 19200 and the device ID is according to your wiring diagram.

    

5. Verify that Port 1 on the Elara is “host”.

A negative reading is obtained because the power source cable passes through the current ring in the wrong direction

1. As shown in the picture below, make sure the phase direction is correct
   
   

    

The phases cables of the AC ring connected to the wrong pins in the AC meter

1. Verify you connect the cables from the CT ring to the AC meter according to the relevant phases.
   
   Pin 4 > Phase 1 Current [+] > Red cable
   Pin 5 > Phase 1 Current [-] > Black cable
   Pin 6 > Phase 2 Current [+] > Red cable
   Pin 7 > Phase 2 Current [-] > Black cable
   Pin 8 > Phase 3 Current [+] > Red cable
   Pin 9 > Phase 3 Current [-] > Black cable
