pany and/or CIRCUTOR's after-sales service.
2. PRODUCT DESCRIPTION
The line-CVM-D32 is a device that measures, calculates and displays the main electrical parameters
in single-phase mains, two-phase mains with and without neutral, and balanced three-phase mains
with ARON measurement or unbalanced. Measurement is performed at true RMS value, using three
AC voltage inputs and three current inputs.
Current measurement is performed indirectly through/5A,/1A transformers or efficient MC1 and MC3
series transformers (/0.250A).
The device features:
-Display to display parameters.
- 3 keys to browse through the different screens and program the equipment.
-2 digital transistor outputs.
- RS-485 communications, with MODBUS RTU© protocol.

3. INSTALLATION OF THE DEVICE
3.1.- PRELIMINARY RECOMMENDATIONS
In order to use the device safely, personnel operating it must follow the safety meas-
ures that comply with the standards of the country where it is to be installed; operators
must wear the required personal protective equipment (rubber gloves, approved facial
protection and flame-resistant clothing) to prevent injuries from electric shock or arcs
caused by exposure to current-carrying conductors, and they must heed the various
warnings indicated in this instruction manual.
The line-CVM-D32 device must be installed by authorised, qualified personnel.
The power supply plug must be disconnected and measurement systems switched off before handling,
altering the connections or replacing the device. It is dangerous to handle the device while it is pow-
ered.
Cables must always be kept in perfect condition to avoid accidents or injury to personnel or installa-
tions.
Restrict the operation of the device to the specified measurement category, voltage or current values.
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.
Do not use the device to take any measurements if an anomaly or malfunction is detected.
Check the surrounding environment before starting to take measurements. Do not take any measure-
ments in hazardous or explosive environments.
Before carrying out maintenance, repair or handling of any of the device's connections,
the device must be disconnected from all power sources, both from the device's own
power supply and the measurement's.
Contact the after-sales service if you detect that the device is not working properly.

Instruction Manual
3.2.- INSTALLATION
When the device is on, its terminals, opening covers or removing elements may ex-
pose the user to parts that are hazardous to touch. Do not use the device until it is
fully installed.
The device must be installed inside a medium or low voltage electric panel or enclosure, with DIN rail
mounting (IEC 60715).
The minimum recommended distance between rails to install the line-CVM-D32 devices is 150 mm.
The device must be connected to a power supply circuit protected by gl type (IEC 269) or M type fuses,
between 0.5 and 2A. It must be fitted with a circuit-breaker or equivalent device to disconnect the
device from the mains supply.
The power supply and voltage measurement circuits must be connected with a 1mm² minimum
cross-section cable.
The current transformer's secondary line must have a 2.5 mm2minimum cross-section.
The insulation temperature of the cables connected to the device must be at least 62°C.
The device has an internal clock that has to be configured correctly before
measurements can be taken, see “6.3.- DEVICE CLOCK SETTING”.
3.3.- PANEL ADAPTER 72 x 72 mm
Note: The 72 x 72 mm panel adapter is a separately sold accessory.
CIRCUTOR has a panel adapter for the line-CVM-D32 devices and their expansion modules for their
installation in 72 x 72 mm panels.
Figure 1 illustrates how the panel adapter connects to a line-CVM-D32.
Before installing the adapter, the device must be disconnected from all power and
measurement supplies.

3.5.- EXPANSION WITH OTHER DEVICES
The line-CVM-D32 devices can be expanded with other devices in the Line range, and with the line-
EDS and line-M expansion modules .
The line-EDS and line-CVM devices enable up to 2 expansion modules to be directly connected to their
right-hand side(1).

(1) Expansion module types: line-M-4IO-R, line-M-4IO-T, line-M-4IO-RV, line-M-4IO-A, line-M-20I and line-TCPRS1.
The line-M-3G module can only be connected on the left side of line-EDS devices. If the line-EDS has
a line-M-3G connected to it, only 1 expansion module can be connected on its right side.
In installations with line-EDS devices,a total of up to seven devices may be connected to their right-
hand side.
