Image 3.3: This image illustrates the physical dimensions of the single-phase energy meter. Key measurements shown are 45mm width at the top, 79mm total width at the base, 66mm total height, and 43mm depth from the mounting surface.
4. Asennus ja asennus
The EVURU DDS662 meter is designed for 35mm DIN rail installation. Ensure the power supply is disconnected before proceeding with installation.
Asennusvaiheet:
- Mount the meter onto a standard 35mm DIN rail in your electrical panel.
- Identify the Live (L) and Neutral (N) wires of your single-phase AC supply.
- Connect the wires according to the wiring diagram provided below. The meter supports two wiring modes: upper input/lower output and lower input/upper output. Ensure correct polarity.
- Secure all wire connections firmly using appropriate tools.
- Kun johdotus on valmis ja tarkistettu, kytke virta takaisin piiriin.
Wiring Diagram (DDS662):

Image 4.1: This diagram illustrates the wiring connections for the DDS662 energy meter. It shows the Live (L) and Neutral (N) input connections at the top and corresponding output connections at the bottom, indicating the direction of current flow through the meter.
Wiring Diagram (DDS667):

Image 4.2: This diagram shows the wiring for the DDS667 energy meter integrated with circuit breakers. It details the connections of Live (L) and Neutral (N) wires from the main supply, through a circuit breaker, into the meter, and then out to another circuit breaker before reaching the load.
Wiring Diagram (DDS668):

Image 4.3: This image presents two wiring configurations for the DDS668 energy meter. The left diagram shows the standard upper input (N, L) and lower output (N, L) connections. The right diagram illustrates an alternative configuration with lower input (N, L) and upper output (N, L) connections.
5. Käyttöohjeet
Once installed and powered, the meter will automatically begin measuring. The LCD display will show various parameters, which can be cycled through using the manual button.
Näytön toiminnot:
- Kokonaisenergia (kWh): This value represents the cumulative energy consumption and cannot be reset.
- Tilapäinen energia (kWh): This value represents energy consumption since the last reset. It can be reset to zero.
- Real Voltage (V): Displays the instantaneous voltage piiristä.
- Real Current (A): Displays the instantaneous current flowing through the circuit.
- Todellinen teho (W): Displays the instantaneous active power consumption.
Painikkeen toiminta:
- Lyhyt painallus: Press the button briefly to cycle through the different display parameters (Total kWh, Temporary kWh, Voltage, Current, Power).
- Pitkä painallus (6 sekuntia): Press and hold the button for approximately 6 seconds to reset the Temporary Energy (kWh) to zero. The Total Energy (kWh) cannot be reset.
Pulse LED Indicator:
The pulse LED on the meter indicates active energy measurement. It will flash at a rate of 1000 pulses per kWh, providing a visual confirmation of energy consumption.
