pollution level 2 according to EN 61010-1 standard.

SAFETY WARNINGS

To guarantee correct installation, proceed as follows:

1) The appliance should be installed by a qualiﬁed operator

2) The appliance should be installed in a panel in such a way as to guarantee that the

terminals are inaccessible after ﬁtting

3) A protection device against over-currents should be installed in the electrical system,

upstream of the energy meter

4) Connect the instrument as shown in the alongside diagrams

5) Before touching the connector terminals make sure that the wires to be connected or

already connected to the instrument are not live

6) Do not power or connect the instrument if any part of it is damaged

8) The instrument must be installed and activated in compliance with current electric

systems standards.

• Storage temperature: -20 ÷ +60 °C

• Relative humidity: 10% ÷ 90% non-condensing

• Connection type: direct for current conductors

• Signaling leds: green = power on

red = ﬂashing at 10Wh

• Accuracy: class 2 (EN 62053-21)

• Display: 6-digit mechanical counter

• Reading resolution: 0,1 kWh (full scale: 99999,9 kWh)

• Housing: 2 DIN, gray RAL 7035

• Protection degree: IP20/IP51 on the front

OPERATION

• In normal operation, the green led is on and the red led ﬂashes in proportion to the

active power (ﬂashing at 10Wh).

The meter counts the consumption of active power with a resolution of 0,1 kWh.

PHASE ERROR

• When the energy meter is turned on, a connection check-up is automatically carried out

to detect any connection errors: in case of improper connection, the red and green leds

ﬂash alternate and the meter is locked.

Warning: to restore correct meter operation after an error reading has been

showed, switch the meter off, invert connections of voltage or current

and turn on again.

Do you have a question about the Vemer Energy-230 LC and is the answer not in the manual?

The Vemer Energy-230 LC is a single-phase active energy meter designed for use in 230V systems. It is intended for environments with measurement category III and pollution level 2, adhering to the EN 61010-1 standard.

Function Description:

The primary function of the Energy-230 LC is to measure and display active energy consumption. It features a 6-digit mechanical counter for total energy readings and provides visual feedback through two LEDs: a green LED to indicate power-on status and a red LED that flashes in proportion to the active power consumption, with each flash representing 10Wh. The meter counts active power consumption with a resolution of 0.1 kWh.

Upon power-on, the device performs an automatic connection check-up to detect any wiring errors. In the event of an improper connection, both the red and green LEDs will flash alternately, and the meter will lock. To rectify such an error and restore normal operation, the user must switch the meter off, invert the voltage or current connections, and then power it on again.

Important Technical Specifications:

Power Supply: 230 V CA (-15%/+10%), 50/60 Hz
Maximum Power Consumption: 4 VA
Basic Current (Ib): 15A
Maximum Current (IMAX): 22.5 A
Starting Current: ≤ 50 mA
Current Circuit Consumption: < 2 VA
Operating Temperature: -10 ÷ +45 °C
Storage Temperature: -20 ÷ +60 °C
Relative Humidity: 10% ÷ 90% non-condensing
Connection Type: Direct for current conductors
Signaling LEDs:
- Green: Power on
- Red: Flashing at 10Wh
Accuracy: Class 2 (EN 62053-21)
Display: 6-digit mechanical counter
Reading Resolution: 0.1 kWh (full scale: 99999.9 kWh)
Housing: 2 DIN, gray RAL 7035
Protection Degree: IP20/IP51 on the front
Dimensions: 35.6 mm (width) x 87.5 mm (height) x 60 mm (depth)

Usage Features:

The Energy-230 LC is designed for straightforward installation and operation. It features a terminal block for direct connection of metering wires. The total energy consumed is displayed on a mechanical counter, ensuring readability even without power. The green LED provides an immediate visual confirmation that the device is powered on, while the red flashing LED offers real-time feedback on active power consumption. The compact 2 DIN housing allows for easy integration into electrical panels.

Maintenance Features:

The manual does not explicitly detail routine maintenance procedures. However, the device's robust design with an IP20/IP51 protection degree suggests minimal maintenance requirements in typical operating environments. The self-diagnostic feature for connection errors at power-on simplifies troubleshooting in case of installation issues. The warning regarding error correction (switching off, inverting connections, and restarting) provides a clear procedure for resolving common operational problems related to wiring. The device is designed for installation by a qualified operator, which inherently contributes to proper setup and reduces the likelihood of issues requiring extensive maintenance.
