1. VERIFICATION UPON RECEPTION
Check the following points when you receive the device:
a) The device meets the specifications described in your order.
b) The device has not suffered any damage during transport.
c) Perform an external visual inspection of the device prior to switching it on.
d) Check that it has been delivered with the following:
- An installation guide,
- 1 retainer to secure the device to the DIN rail,
- 4 connectors.
- 2 terminal covers.
If any problem is noticed upon reception, immediately contact the transport com-
pany and/or CIRCUTOR's after-sales service.
2. PRODUCT DESCRIPTION
The CVM-E3-MINI device measures, calculates and displays the main electrical parameters of the
following networks: single-phase, two-phase, with and without neutral, balanced three-phase, with
ARON measurements or unbalanced.The measurement will be taken in RMS with the three AC voltage
inputs and three current inputs.
There are 6 versions of the device, in accordance with current input:
CVM-E3-MINI-ITF and CVM-E3-MINI-ITF-WiEth, indirect current measurement with/5A or
/1A transformers.
CVM-E3-MINI-MC and CVM-E3-MINI-MC-WiEth, indirect current measurement with effi-
cient MC1 and MC3 series transformers.
CVM-E3-MINI-FLEX and CVM-E3-MINI-FLEX-WiEth, current measurement through Ro-
gowski sensors.

3. DEVICE INSTALLATION
3.1.- PRIOR RECOMMENDATIONS
In order to use the device safely, it is critical that individuals who handle it follow the
safety measures set out in the standards of the country where it is being used, use the
necessary personal protective equipment, and pay attention to the various warnings
indicated in this instruction manual.
The CVM-E3-MINI device must be installed by authorised and qualified staff.
The power supply plug must be disconnected and measuring systems switched off before handling, al-
tering the connections or replacing the device. It is dangerous to handle the device while it is powered.
Also, it is critical to keep the cables in perfect condition in order to avoid accidents, personal injury and
damage to installations.
The manufacturer of the device is not responsible for any damage resulting from failure by the user
or installer to heed the warnings and/or recommendations set out in this manual, nor for damage
resulting from the use of non-original products or accessories or those made by other manufacturers.
If an anomaly or malfunction is detected in the device, do not use it to take any measurements.
Inspect the work area before taking any measurements. Do not take measurements in dangerous ar-
eas or where there is a risk of explosion.
Disconnect the device from the power supply (device and measuring system power
supply) before maintaining, repairing or handling the device's connections.
Please contact the after-sales service if you suspect that there is an operational fault
in the device.

CVM-E3-MINI
Instruction Manual

3.2.- INSTALLATION
The device must be installed on an electric panel or enclosure, attached to a DIN rail (IEC 60715).
The minimum recommended distance between rails for installing the CVM-E3-MINI device is 150 mm.
Terminals, opening covers or removing elements can expose parts that are hazardous
to the touch while the device is powered. Do not use the device until it is fully installed.
The device must be connected to a power circuit that is protected with gl (IEC 269) or M type fuses with
a rating of 0.5 to 2 A. It must be fitted with a circuit breaker or equivalent device, in order to be able to
disconnect the device from the power supply network.
The power and voltage measuring circuit must be connected with cables that have a minimum
cross-section of 1mm2.
The secondary line of the current transformer will have a minimum cross-section of 2.5 mm2.
The temperature rating of insulation of wires connected to the device will be at minimum 62ºC.
3.3.- PANEL MOUNTING ACCESSORY (72 x 72 mm)
Note: The 72 x 72 mm panel mounting accessory is an accessory that is sold separately.
CIRCUTOR has a panel mounting accessory of the CVM-E3-MINI equipment so that it can be installed
on 72 x 72 mm panels.
Figure 1: CVM-E3-MINI with panel mounting accessory.
Figure 2 shows the installation of the panel mounting accessory to the CVM-E3-MINI.
Disconnect all power supplies and measuring equipment from the device before carry-
ing out the installation of the panel mounting accessory.

3.4.- CVM-E3-MINI-FLEX: ROGOWSKI SENSORS
The CVM-E3-MINI-FLEX model measures currents using flexible sensors, based on the Rogowski coil
principle.
The flexibility of the sensor allows it to measure an alternating current irrespective of the position of
the conductor.
CIRCUTOR has 1 Rogowski sensor model that can be used with the CVM-E3-MINI-FLEX: FLEX-MAG.
Table 6 shows the connection of the sensors and Table 5 the maximum position error.
Note: For more information, consult the corresponding sensor guide.
