4. Operating Principle

The unit measures the active electrical energy consumed by the connected load, integrating power over time. The total consumed energy value is displayed in kilowatt-hours (kWh).

5. Connection Diagram (Description)

The unit is supplied with phase and neutral wire connections:

• L IN - phase input
• N IN - neutral input

The pulse output is via two separate terminals:

• PULSE +
• PULSE -

This output is electrically isolated via an optical coupler. Warning: Connections must be made exclusively by authorized personnel.

6. Installation Instructions

• Install on a 35 mm DIN rail inside the electrical panel
• Securely mount to prevent vibrations
• Connect according to the electrical wiring diagram
• After powering on, the LED display will begin indicating the accumulated consumption

7. Pulse Output

The pulse output allows:

• Monitoring consumption via external systems
• Integration with PLC or automation systems
• Recording real-time consumption data

This output is not Modbus, RS485, or WiFi. It is solely an optical pulse output.

8. Application Areas

• Residential electrical installations
• Industrial electrical panels
• Monitoring of specific circuit consumption
• Automation and BMS systems
• Commercial and administrative applications

9. Recommendations

• It is not recommended for use in circuits exceeding 30 A
• For higher currents, use a meter with a broader range
• Not intended for official billing measurements by energy suppliers
