CVM-C11

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,
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-C11 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 meas-
urements or unbalanced. The measurement will be taken in RMS with the three AC voltage inputs and
four current inputs.
There are 4 versions of the device, depending on the type of current input:
CVM-C11-ITF-IN-485-ICT2 and CVM-C11-ITF-IN-ETH-ICT2 model measures current through/5A
or/1A transformers.
CVM-C11-FLEX-IN-485-ICT2 current measurement through Rogowski sensors.
CVM-C11-MC-IN-485-ICT2 indirect current measurement with efficient transformers of the MC1
and MC3 series.
The device features:
- 3 keys that allow you to browse between the various screens and program the device.
- 2 indicator LEDs.
- LCD display, displays all parameters.
- 2 digital inputs, used to select the tariff, detect the logic state of external signals or to gen-
erate a synchronism pulse to calculate the maximum demand.
- 2 digital outputs, fully programmable.
- 2 alarm relays, fully programmable.
- RS-485 Communications, with two serial protocols: MODBUS RTU© and BACnet.
- Ethernet Communications (CVM-C11-ITF-IN-ETH-ICT2 Model), with two serial protocols:
MODBUS TCP and BACnet IP.

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-C11 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.
3.2.- INSTALLATION
The device will be installed on a panel (92+0.8 x 92+0.8 mm panel drill hole, in compliance with IEC 61554).
All connections are located inside the electric panel.
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 type gL (IEC 60269) or class M
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.

3.3.- CVM-C11-FLEX-IN-485-ICT2: ROGOWSKI SENSORS
The CVM-C11-FLEX-IN-485-ICT2 model measures currents using flexible sensors, based on the Ro-
gowski 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-C11-FLEX-IN-485-ICT2: MFC-
FLEX.
Note: For more information, consult the corresponding sensor guide.
