1.- VERIFICATION UPON RECEPTION
Check the following points when you receive the unit:
a)The unit meets the specifications described in your order.
b)The unit has not suffered any damage during transport.
c)Perform an external visual inspection of the unit prior to switching it on.
d)Check that it has been delivered with the following:
-An installation guide,
-2 Retainers used to attach the unit,
-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 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 efficient 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.
-2 digital outputs, fully programmable.
(Not available in the CVM-C10-ITF-IN model)
-2 alarm relays, fully programmable.
-RS-485 Communications, with two serial protocols: MODBUS RTU© and BACnet.

3.- UNIT INSTALLATION
3.1.- PRIOR RECOMMENDATIONS
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 qualified staff.
The power supply plug must be disconnected and measuring systems switched off before handling, 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 dangerous 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.

CVM-C10
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 2A. It must be fitted 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”)
