5.2 Installation Steps
- Power Disconnection: Ensure all power to the installation area is completely disconnected at the main breaker.
- Mounting: Mount the device securely on a DIN rail within an appropriate electrical enclosure.
- Wiring:
- Connect the three-phase live wires (L1, L2, L3) to their respective terminals on the device.
- Connect the Neutral (N) wire to the designated neutral terminal.
- Ensure all connections are tight and secure to prevent loose contacts and overheating.
- Verification: Double-check all wiring against the diagram (Figure 5.1) before restoring power.
- Power Restoration: Carefully restore power to the system. The device display should illuminate.
6. Setup and Configuration
6.1 Parameter Settings
Figure 6.1: Setting parameter flow chart and Wi-Fi indicator status.
- Enter Settings: Long press and hold the Setting button (top right button with gear icon, visible in Figure 3.1) to enter the setting status display page. The data bits will flash.
- Adjust Value: Use the Up (second button from top right, visible in Figure 3.1) and Down (third button from top right, visible in Figure 3.1) buttons to set the content of the flashing data bit.
- Switch Bit/Parameter: Short press the Setting button to switch to the next setting bit or parameter.
- Confirm and Next: Short press the OK button (bottom right button, visible in Figure 3.1) to confirm the settings on the current page and jump to the next settings page.
- Exit and Save: Long press the OK button to exit the setting state and save all configured settings.
Refer to the "Specifications" section (Table 4.1) for the adjustable ranges and default values of each parameter, including voltage limits, current limits, and various delay times.

7.2 Protection Functions
The device automatically monitors the electrical system and activates protection mechanisms based on the configured settings:
- Over-Voltage Protection: If any phase voltage exceeds the "Upper Voltage Limit" for the "Over and Under Voltage Event Time Threshold", the device will trip and disconnect the load.
- Under-Voltage Protection: If any phase voltage drops below the "Lower Voltage Limit" for the "Over and Under Voltage Event Time Threshold", the device will trip and disconnect the load.
- Over-Current Protection: If the current in any phase exceeds the "Upper Current Limit" for the "Overcurrent Event Threshold Time", the device will trip and disconnect the load.
- High Temperature Alarm: An alarm will be triggered if the internal temperature exceeds the "High Temperature Alarm" threshold.
- Automatic Reconnection: After a protection event, the device will automatically attempt to reconnect after the respective recovery delay time (e.g., "Overcurrent Recovery Power-On Delay Time", "Over and Under Voltage Event Recovery Power-On Delay Time") has elapsed and the fault condition has cleared.
8. Maintenance
The EAEMP3-100-TY-W is designed for reliable operation with minimal maintenance. However, periodic checks are recommended:
- Visual Inspection: Regularly inspect the device and its wiring for any signs of damage, loose connections, or discoloration.
- Cleaning: Keep the device clean and free from dust. Use a soft, dry cloth for cleaning. Do not use liquid cleaners or solvents.
