Product Information
Full details
The Carlo Gavazzi EM340 series energy meter is designed for businesses and facilities requiring precise active energy measurement and cost allocation for up to 65 A applications. Its key benefit lies in its dual tariff management and ability to measure both imported and exported energy, offering flexibility in energy management. A potential caveat is its direct connection limit of 65 A, which may require external current transformers for higher loads. The meter features a backlit LCD, integrated touch keypad, pulse output, and self-power supply for straightforward integration and monitoring.

Extended Product Information
FAQs
What is the maximum current the EM340 can measure directly?
The EM340 series can measure active energy directly up to 65 A. For loads exceeding this, external current transformers (CTs) must be used.
Can this meter measure both imported and exported energy?
Yes, the EM340 is indicated for measuring both imported and exported energy. It can also be programmed to consider only imported energy if needed.
What does 'dual tariff management' mean?
Dual tariff management allows the meter to record energy consumption at two different rates, typically based on time of day (e.g., peak and off-peak hours), which is useful for cost allocation and optimizing energy usage.
Does the meter require a separate power supply?
No, the EM340 features a self-power supply, meaning it operates using the energy from the measured three-phase supply, simplifying installation.
What is the meaning of 'wrong current direction detection'?
This feature detects if the current is flowing in the opposite direction to what is expected, which can indicate incorrect wiring or unusual power flow, and typically triggers an alert.
What is the protection rating of the front display?
The front protection degree is IP51, meaning it is protected against dust ingress and vertically falling water drops.
How do I reset the meter readings?
Refer to the product manual for specific instructions on resetting meter readings. Typically, this involves a sequence of button presses or a specific configuration setting.
Troubleshooting
Meter not powering on
Verify that the three-phase supply voltage is correctly connected to the appropriate terminals and that the supply is active. Ensure all connections are secure.
Display shows error message or no reading
Check the wiring connections for correctness and security. Refer to the product manual for specific error code meanings. Ensure the current direction is not reversed if the detection feature is active.
Inaccurate energy readings
Confirm that the meter's current rating (e.g., 65 A direct or CT ratio) is correctly configured and matches the actual load. Double-check all wiring, especially for phases and neutral.
Pulse output not functioning
Ensure the pulse output terminals are correctly wired to your monitoring device. Verify that the meter is actively measuring energy, as the pulse output is typically generated based on energy consumption.
Pros and Cons
Pros
- Accurate measurement of active energy (imported and exported).
- Flexible configuration for dual tariff or single tariff usage.
- Easy to read backlit LCD display with touch controls.
- Direct connection capability up to 65 A simplifies installation in many scenarios.
- Pulse output for integration with external systems.
- Built-in detection for incorrect current direction.
Cons
- Direct connection limited to 65 A; higher loads require external CTs.
- Front protection degree of IP51 may limit use in very dusty or wet environments.
- Primarily focused on active energy; reactive energy measurement is not a stated feature.
- Configuration might require specific technical knowledge for advanced settings like dual tariffs.
Setup, Compatibility & Care
Setup: The EM340 is designed for DIN rail mounting. Ensure correct wiring according to the manual, paying close attention to the voltage and current input terminals. For direct connection, ensure the total load does not exceed 65 A. If higher currents are present, external current transformers (CTs) must be used and configured correctly within the meter's settings. The meter is self-powered, meaning it draws power from the measured supply.
Compatibility: The meter is compatible with standard three-phase electrical systems. The pulse output can be connected to most common energy monitoring or data acquisition systems that accept pulse inputs. Refer to the product manual for specific compatibility details regarding communication protocols if using advanced integration.
Care: Keep the meter clean and free from dust and moisture. The front panel can be cleaned with a slightly damp cloth. Avoid using abrasive cleaners or solvents. Ensure ventilation around the meter is adequate to prevent overheating. Regular visual inspection for any signs of damage is recommended.
