3.2 Components and Display

Figure 3.2.1: Front view of the EAMPDW-TY-63-B Smart Energy Meter and Protector. The display shows voltage (V), current (A), and kilowatt-hour (kWh) readings. Buttons for 'SET', 'Up/Down', and 'Power' are visible at the bottom. Input terminals (IN) are at the top, and output terminals (OUT) are at the bottom.

The device features a clear digital display showing real-time electrical parameters such as voltage (V), current (A), and accumulated energy consumption (kWh). It also indicates leakage current (mA). Control buttons ('SET', 'Up/Down arrows', 'Power') allow for parameter adjustment and device control.

4. Setup and Installation

Before installation, ensure the main power supply is turned off at the circuit breaker or fuse box. This device is designed for DIN rail mounting.

4.1 Wiring Diagram

Connect the incoming live (L) and neutral (N) wires to the "IN" terminals at the top of the device. Connect the outgoing live (L) and neutral (N) wires to the "OUT" terminals at the bottom of the device. Ensure all connections are tight and secure.

• IN (Top): Connect to the main power source.
• OUT (Bottom): Connect to the load (appliances/circuit).

Refer to local electrical codes and standards for proper wiring practices.

5. Operating Instructions
