Instruction Manual

1.- VERIFICATION UPON RECEPTION
Check the following points when you receive the device:
a) The device meets the specications 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,
- 2 Retainers used to attach the device,
- 5 connectors.
If any problem is noticed upon reception, immediately contact the transport
company and/or CIRCUTOR's after-sales service.
2.- PRODUCT DESCRIPTION
The CVM-C10 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 5 versions of the device, depending on the type of current input:
CVM-C10-ITF, indirect current measurement with /5A or /1A transformers.
CVM-C10-ITF-IN, indirect current measurement with /5A or /1A transformers and an
input to measure the neutral current.
CVM-C10-MC, indirect current measurement with efcient transformers of the
MC1 and MC3 series.
CVM-C10-mV indirect current measurement with /0.333V transformers.
CVM-C10-FLEX current measurement through Rogowski sensors.
The device features:
- 3 keys that allow you to browse between the various screens and program the device.
- 3 indicator LEDs: CPU, ALARM and KEY.
- LCD display, displays all parameters,
- 2 digital inputs, used to select the tariff or detect the logic state of external signals.
- 2 digital outputs, fully programmable.

3.- UNIT 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 vari-
ous warnings indicated in this instruction manual.
The CVM-C10 device must be installed by authorised and qualied staff.
The power supply plug must be disconnected and measuring systems switched off before
handling, altering 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 measure-
ments.
Inspect the work area before taking any measurements. Do not take measurements in danger-
ous areas 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.

Instruction Manual
CVM-C10

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 DIN
43700). All connections are located inside the electric panel.
Terminals, opening covers or removing elements can expose parts that are haz-
ardous 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 tted 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.- CVM-C10-FLEX: ROGOWSKI SENSORS
The CVM-C10-FLEX model measures currents using exible sensors, based on the Rogowski
coil principle.
The exibility of the sensor allows it to measure an alternating current irrespective of the posi-
tion of the conductor.
The unit has 2 measurement scales with automatic changes,
Table 2:Rogowski sensors for current measurements.
Type Code Scale Accuracy(1) Full scale Length Diameter
FLEX-MAG70 M818110041500 0 ... 500 A~ ± 1% of the range 1000 A / 100 mV~ 2 m 70 mm
500 ... 1000 A ~ ± 1% of the range
FLEX-MAG120 M818120041500 0 ... 500 A ~ ± 1% of the range 1000 A / 100 mV~ 2 m 120 mm
500 ... 1000 A ~ ± 1% of the range
(1) The measurement accuracy is for the sensor in its optimal position, with no external electric or magnetic
elds and within the working temperature range.
