2�- PRODUCT DESCRIPTION
The CVM-C10 unit 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 3 versions of the unit, 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 efcient transformers of the
MC1 and MC3 series.
CVM-C10-mV indirect current measurement with /0.333V transformers.
The unit features:
- 3 keys that allow you to browse between the various screens and program the unit.
- 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.
In order to use the unit 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-C10 unit must be installed by authorised and qualied staff.
The power supply plug must be disconnected and measuring systems switched off before han-
dling, altering the connections or replacing the unit. It is dangerous to handle the unit 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 unit 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 unit, do not use it to take any measurements.
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 unit from the power supply (unit and measuring system power
supply) before maintaining, repairing or handling the unit's connections.
Please contact the after-sales service if you suspect that there is an operational
fault in the unit.

3.2.- INSTALLATION
The unit 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 hazardous to the touch while the unit is powered. Do not use the unit until it is fully
installed.
The unit 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 unit 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.

4.3.- DISPLAY
The unit has a backlit LCD display showing all the parameters listed in Table 3.
The display is divided into four areas (Figure 14):
Figure 14: CVM-C10 Display areas
The area with data per phase displays the instantaneous, maximum and minimum
values of each phase being measured or calculated by the unit.
The total data area displays the totals of the values being measured or calculated by
the unit.
Analogue bar, displays the % of the current power of the installation.
Cos φ - PF Bar, displays the value of the system's Cos φ or power factor in real time.
4�3�1� COS φ - PF (POWER FACTOR) BAR
Figure 15: Cos φ - PF Bar
This bar displays the value of the installation's cos φ or power factor in real time.
The parameter that will be displayed is selected on the programming menu. ( “4.9.13. Selecting
the Cos φ - PF bar on the display”)
