6. Орнотуу
6.1 Монтаждоо
The energy meter is designed for 35mm DIN rail installation. Ensure a secure fit within your electrical panel.
6.2 CT Clamp Орнотуу
The Current Transformer (CT) clamps are crucial for current measurement. Each CT clamp has an arrow or 'P1→P2' / 'K→L' marking on its body or a sticker. This indicates the direction of current flow. The CT supports bidirectional sensing. If the current direction is opposite to the CT's marking, the power reading will be negative. Ensure the CT is applied to the correct cable and its direction is consistent with your measurement needs.

6.3 Электр зымдары боюнча нускамалар
Refer to the wiring diagrams below for proper connection. Connect the AC input lines to the appropriate terminals (L1, L2, L3, N) and the CT clamps to the respective phase cables. Ensure all connections are tight and secure.
Маанилүү эскертүү: A circuit breaker and a shunt trip device are required for the protection functions to operate. These are NOT included in the package and must be purchased separately if needed.
6.3.1 Energy Meter + Protector Wiring Diagram
Figure 6: Wiring for Energy Meter with Protector Functions
For the protector function with a shunt trip release:
- Connect the other wire of the shunt trip release to terminal 16 (Normally Open - NO).
- Connect the neutral wire (N) from the electric meter to the common (COM) terminal 15.
- Terminal 15 is the common contact (COM). Terminal 16 is the Normally Open (NO) contact, with a maximum load capacity of 5A.
Wiring Instructions for a Three-Phase Circuit Breaker with an Integrated 220V Shunt Trip Release:
Connect one wire of the shunt trip release to the C-phase (Phase C) point of the circuit breaker's output line. WARNING: This wire can only be connected with the circuit breaker output line, not the input line. If connected to the input line, the Shunt Trip Release will be burnt!

9. Колдонуучунун кеңештери
- Wi-Fi туташуусу: If you experience issues with the Wi-Fi function, ensure your router is broadcasting a 2.4GHz network. Check that the device is in pairing mode (blinking Wi-Fi indicator) and verify your Wi-Fi password in the app.
- Коргоо жөндөөлөрү: Carefully configure the over/under voltage and current limits to match your specific electrical system requirements to prevent nuisance tripping or inadequate protection.
- Энергия мониторинги: Utilize the app's energy statistics to track daily, monthly, and yearly consumption. This can help identify energy usage patterns and potential savings.
10. Кыйынчылыктарды
| Көйгөй | Мүмкүн себеп | Чечим |
|---|---|---|
| Wi-Fi function not working / Device won't connect to app | Incorrect Wi-Fi credentials, 5GHz network, device not in pairing mode, weak signal. | Ensure your Wi-Fi is 2.4GHz. Verify Wi-Fi password. Put the device into pairing mode (refer to app instructions for specific steps). Check Wi-Fi signal strength near the device. |
| Түзмөк күйбөй жатат | No power supply, incorrect wiring, internal fault. | Check main power supply. Verify wiring connections according to diagrams. If power is present and wiring is correct, contact support. |
| Incorrect energy readings | CT clamp installed incorrectly (reversed direction), faulty CT clamp, incorrect multiplier settings in app. | Check CT clamp direction (arrow should point towards load). Ensure CT clamps are securely closed. Verify voltage and current multiplier settings in the app. |
| Protection (e.g., over-voltage) not triggering | Protection function disabled, threshold set too high/low, no shunt trip release connected. | Enable the specific protection function in the app or via device buttons. Adjust the threshold to an appropriate value. Ensure a compatible shunt trip release is correctly wired if using protector features. |
| Device frequently trips/shuts off | Protection thresholds set too sensitively, actual load exceeding limits. | Review and adjust protection thresholds (e.g., over current, over voltage) to prevent nuisance tripping. Check actual load to ensure it's within the device's and CT's rated capacity. |
