6. Setup

6.1 Installation

1. Power Disconnection: Before beginning installation, ensure that the main power supply to the circuit is completely disconnected at the service panel.
2. Mounting: The EAWCBT-P is designed for 35MM DIN rail installation. Snap the device onto the DIN rail securely within your electrical panel.
3. Wiring:
   • Connect the incoming Neutral (N) and Live (L) wires to the 'N IN' and 'L IN' terminals at the top of the device, respectively.
   • Connect the outgoing Neutral (N) and Live (L) wires to the 'N OUT' and 'L OUT' terminals at the bottom of the device, respectively, leading to the load.
   • Ensure all wire connections are tight and properly insulated.
4. Verification: Double-check all connections for correctness and security before restoring power.

6.2 APP Connection (Remote Control)

To utilize the remote control and advanced monitoring features, download the compatible mobile application (refer to product packaging or manufacturer's website for specific APP name). Follow the in-app instructions to pair your device. This typically involves:

1. Ensuring your mobile device is connected to a 2.4GHz Wi-Fi network.
2. Placing the circuit breaker in pairing mode (often indicated by a flashing LED, refer to APP for specific steps).
3. Following the APP's prompts to connect the device to your Wi-Fi network.

7. Operating Instructions

7.1 Basic On/Off Operation

• Manual Control: Press the large circular power button on the front of the device to manually switch the circuit breaker ON or OFF.
• Remote Control: Once connected to the APP, you can remotely switch the device ON or OFF from anywhere.

7.2 Setting Protection Thresholds via APP

The EAWCBT-P allows you to set various protection thresholds to safeguard your electrical appliances. Access these settings through the connected mobile application:

• Current Limit: Set the maximum allowable current (1-63A). If the real-time current exceeds this value, the device will trip.
• Power Limit: Set the maximum allowable power (1-26KW). If the real-time power consumption exceeds this value, the device will trip.
• Overvoltage Protection: Define the upper voltage limit (220-265V). The device will trip if the voltage goes above this setting.
• Undervoltage Protection: Define the lower voltage limit (76-240V). The device will trip if the voltage drops below this setting.
• Temperature Protection: Set a temperature threshold (40-150°C). The device will trip if its internal temperature exceeds this value, preventing overheating.

When a threshold is reached, the connected appliance will automatically shut down to prevent damage. You can reset the breaker manually or via the APP after addressing the cause of the trip.

7.3 Energy Monitoring

The APP provides real-time energy consumption data. You can:

• Monitor current, voltage, and power consumption.
• Track kilowatt-hour (kWh) usage over time.
• Set electricity prices within the APP to calculate electricity costs.
• Download historical data to a table for analysis.

7.4 Timer and Schedule Functions

Utilize the APP to set schedules and timers for automated operation:

• Schedule: Program the device to turn ON or OFF at specific times on specific days.
• Timer: Set a countdown timer for the device to turn ON or OFF after a set duration.
• Recurring Timer: Configure repetitive ON/OFF cycles.

7.5 Power-on Response

Configure the device's behavior after a power outage and subsequent restoration:

• Restore Previous State: The device will return to its ON or OFF state prior to the power interruption.
• Always ON: The device will always turn ON when power is restored.
• Always OFF: The device will always remain OFF when power is restored.

8. Maintenance

The NGDOLAOV EAWCBT-P Intelligent Circuit Breaker requires minimal maintenance.

• Cleaning: Periodically wipe the exterior of the device with a dry, soft cloth. Do not use abrasive cleaners or solvents. Ensure power is disconnected before cleaning.
• Inspection: Regularly inspect the wiring connections for any signs of loosening or damage.
• Firmware Updates: Check the mobile application periodically for any available firmware updates for the device to ensure optimal performance and security.
