3. Informazzjoni dwar is-Sigurtà

Jekk jogħġbok osserva l-prekawzjonijiet ta' sigurtà li ġejjin biex tevita ħsara lill-apparat jew korriment personali:

• Tagħbija Rated: Ensure that the electrical load connected to the circuit does not exceed the rated power capacity of the meter (22000W) or the current transformer (100A).
• Wiring korrett: Always follow the provided wiring diagram precisely. Incorrect wiring can lead to device malfunction, electrical shock, or fire.
• Użu fuq ġewwa biss: This product is designed for indoor use in dry environments. Do not install or operate this device outdoors or in damp kundizzjonijiet.
• Installazzjoni professjonali: If you are not familiar with electrical wiring, seek assistance from a qualified electrician for installation.
• Skonnettjar tal-Enerġija: Dejjem skonnettja l-enerġija miċ-ċirkwit qabel ma twettaq kwalunkwe installazzjoni, wajers, jew manutenzjoni.

5. Setup u Installazzjoni

Follow these steps for proper installation of the power meter:

1. Skonnettja l-Enerġija: Before starting any wiring, ensure that the main power supply to the circuit is completely disconnected to prevent electrical shock.
2. Mount the Meter: Choose a suitable indoor location for the meter. The meter is designed for panel mounting.
3. Qabbad il-Provvista tal-Enerġija: Connect the AC 80-260V power supply to the meter's input terminals as shown in the wiring diagram. Ensure correct polarity if applicable, though for AC, line and neutral are typically interchangeable for the meter's power input.
4. Installa t-Trasformatur tal-Kurrent (CT):
   • Identify the load wire (live wire) of the circuit you wish to monitor.
   • Open the CT clamp and pass only the load wire through the center hole of the CT. Ensure the arrow on the CT points in the direction of current flow (from source to load).
   • Connect the two wires from the CT clamp to the CT input terminals on the meter.
5. Ivverifika l-Konnessjonijiet: Double-check all wiring connections against the diagram to ensure they are secure and correct.
6. Irrestawra l-Enerġija: Once all connections are verified, restore power to the circuit. The meter display should light up.

6. Istruzzjonijiet Operattivi

The meter is designed for straightforward operation. Once powered on, it will immediately begin displaying real-time measurements.

6.1. Kontroll tad-dawl ta 'wara

To control the display backlight:

• Ixgħel/Itfi: Briefly press the button located on the front panel. Each press will toggle the backlight state.
• Iffrankar tad-Data: The meter automatically saves measurement data regardless of the backlight status.

6.2. Overload Alarm Setting

To set or adjust the current overload alarm threshold:

1. Idħol fil-Modalità ta' Setting: Press and hold the button for approximately 3 seconds until the current alarm threshold value starts flashing on the display.
2. Adjust Threshold: While the value is flashing, briefly press the button to increase the threshold value. The value will cycle through available settings.
3. Issejvja l-issettjar: Stop pressing the button. After 3 seconds of inactivity, the meter will automatically save the new threshold and exit the setting mode.

When the measured current exceeds the set threshold, the backlight will flash to alert you of an overload condition. The flashing will stop once the current drops below the threshold.

6.3. Energy Data Reset

To clear the accumulated energy consumption (kWh) data:

1. Ibda Reset: Press and hold the button for 5 seconds until the energy consumption number starts flashing. Then release the button.
2. Ikkonferma Irrisettja: Briefly press the button again. This action will clear the energy data and stop the flashing.
3. Cancel Reset: If no button operation occurs within 5 seconds after the number starts flashing, the reset will be canceled, and the energy data will remain unchanged.
