2 Safety
This instrument was manufactured and tested in compliance with IEC 61010 class 2 standards for operating
voltages up to 250 VAC rms phase to neutral.
In order to maintain this condition and to ensure safe operation, the user must comply with the indications
and markings contained in the following instructions:
• When the instrument is received, before starting its installation, check that it is intact and no damage
occurred during transport.
• Before mounting, ensure that the instrument operating voltages and the mains voltage are
compatible then proceed with the installation.
• The instrument power supply needs no earth connection.
• The instrument is not equipped with a power supply fuse; a suitable external protection fuse must be
foreseen by the contractor.
• Maintenance and/or repair must be carried out only by qualified, authorized personnel
• If there is ever the suspicion that safe operation is no longer possible, the instrument must be taken
out of service and precautions taken against its accidental use.
• Operation is no longer safe when:
1) There is clearly visible damage.
2) The instrument no longer functions.
3) After lengthy storage in unfavorable conditions.
4) After serious damage occurred during transport
The instruments must be installed in respect of all the local regulations.
2.1 Operator safety
Warning: Failure to observe the following instructions may lead to a serious danger of death.
- During normal operation dangerous voltages can occur on instrument terminals and on
voltage and current transformers. Energized voltage and current transformers may generate
lethal voltages. Follow carefully the standard safety precautions while carrying out any
installation or service operation.
- The terminals of the instrument must not be accessible by the user after the installation. The
user should only be allowed to access the instrument front panel where the display is
located.
- Do not use the digital outputs for protection functions nor for power limitation functions. The
instrument is suitable only for secondary protection functions.
- The instrument must be protected by a breaking device capable of interrupting both the
power supply and the measurement terminals. It must be easily reachable by the operator
and well identified as instrument cut-off device.
- The instrument and its connections must be carefully protected against short-circuit.
Precautions: Failure to respect the following instructions may irreversibly damage to the instrument.
- The instrument is equipped with PTC current limiting device but a suitable external protection
fuse should be foreseen by the contractor.
- The outputs and the options operate at low voltage level; they cannot be powered by any
unspecified external voltage.
- The application of currents not compatible with the current inputs levels will damage to the
instrument.

4.2 Measurement Connections
4.2.1 Voltage connection
Use cables with max cross-section of 4 mm2 and connect them to the terminals marked VOLTAGE INPUT
on the instrument according to the applicable diagrams that follow.
4.2.2 Current connection
It is necessary to use external CTs with a primary rating adequate to the load to be metered and with a 5A
secondary rating. The number of CTs to be used (1, 2 or 3) depends upon the type of network.
Connect the CT output(s) to the terminals marked CURRENT INPUT of the instrument according to the
applicable diagrams that follow.
Use cables with cross-section adequate to the VA rating of the CT and to the distance to be covered. The
max cross-section for the terminals is 4 mm
N.B. The CT secondary must always be in short circuit when not connected to the instrument in order to
avoid damages and risks for the operator.
Warning: THE PHASE RELATIONSHIP AMONG VOLTAGE AND CURRENT SIGNALS MUST BE
CAREFULLY RESPECTED. ALL DISREGARD OF THIS RULE OR OF THE WIRING DIAGRAM

The value is expressed in minutes in a 1 to 60 min. range.
The instrument supports two average values: one calculated by using the sliding window method and the
other one calculated on a fixed time basis. The time setting that is programmed by keyboard is the average
demand integration time with the sliding window method. The Maximum Demand too is calculated on the
sliding window basis.
The integration time on a fixed time basis is used for storing the energy data however this setting is available
only as a MODBUS register via serial port setting.

The first page is the following:
This page enables the setting of respectively:
- communication speed
- number of data bits
- parity
- stop bits
All these data are correlated depending upon the stop bit value.
Additional parameters regarding the MODBUS communication protocol may be
set in the next page:
- Mode: it may be configured to RTU or to ASC (ASCII) mode.
- Slave Address
- Transmission delay; it stands for the time delay the instrument will wait prior
to reply to a data query. It is expressed in milliseconds, the default value is
100 msec and a 0 setting is also possible.
5.1.2.3 Output Configuration
The instrument is equipped with 2 digital outputs that are set by default to operate as pulse outputs
proportional to P
instrument range without any CT and PT multiplier.
The operating mode of digital outputs may be changed to operate as alarm output or as remote output
device controlled by the Modbus protocol.
When operating on the Modbus protocol, in order to ensure a protection to the outputs in case of
communication failure, it is possible to configure a watchdog timer (programmable from 0 to 60 minutes; 0 =
disabled).
The following entry fields are prompted (example for output 1):

5.1.2.5 Alarm Configuration
The Instrument is equipped with two alarms that are triggered by a programmable threshold on anyone of
the measured parameters.
The types of alarm available are: maximum, minimum and 1-of-3.
A minimum alarm is triggered when the selected parameter is lower than the alarm threshold.
A maximum alarm is triggered when the selected parameter exceeds the alarm threshold.
A 1-of-3 alarm is triggered when anyone of the phase readings, whichever the phase involved, trespasses
the alarm threshold – this alarm can be either maximum or minimum. On a 1-of-3 current alarm, the
threshold is expressed as percentage (rather than a value) that stands for the unbalance between the
phases. The alarm therefore triggers when the percent difference between two of the three phases exceeds
the threshold; it is calculated as 100 x (I
All alarms allow also the setting of an hysteresys and a delay time.
The hysteresys (in percent) sets the difference between the triggering threshold and the end threshold (this
prevents repeated alarm triggering when the reading oscillates around the trigger value). Example: a 5%
hysteresys on a threshold of 100, triggers the alarm when the reading exceeds 100 but it will switch off the
alarm when the reading becomes lower than 95.
The delay time sets a time delay for triggering on the alarm after its actual occurrence (or triggering off after
its actual end).
The alarm setup procedure is activated from the output configuration screen or at the end of page

5.1.2.7 Clock calendar configuration (for X3M-D only)
The X3M-D is equipped with a clock/calendar with internal battery having a 15 years life time.
The clock/calendar supports the time zone handling functions and the automatic change from Standard Time
to Daylight Saving Time and vice versa.
The instrument is set by default to the Europe/Rome time and time zone.
The clock/calendar setting is covered by the last two SETUP pages.
Clock format
The following Time formats are foreseen:
Coordinated Universal Time (UTC): commonly known as GMT (Greenwich Mean Time): it is the
universal time, applicable to any place on earth.
Standard Time: it is the local time of a specific time zone, based on the sun cycles (known as Solar
Time
Daylight Saving Time it is the local time of a specific time zone when an offset on standard time is
applied (DST offset). The introduction of this offset allows to increase the availability of hours with
natural light in the summer evenings.
Wall time: it is how we refer to the clock time in each time zone. The Wall time actually coincides with
the Daylight Saving Time or the Standard Time depending whether an offset Solar time is
occurring or not.
The difference between Standard Time and UTC time is called GMT offset.
Summarizing:
GMT offset = UTC – Standard Time
Wall Time = Standard Time + DST offset = UTC + GMT offset + DST offset
The instrument RTC supports the following time information:
• UTC Date/time
• Time zone identification
Starting from the UTC time, the instrument automatically calculates the local time (Wall Time) of any place
on earth
The pertinent time zone is entered to the instrument by a numeric index (time zone index) either on the set
up procedure or on a MODBUS register.
NOTE:
The clock is updated by using the local time or “wall time” that the instrument converts in UTC, consequently,
if the time zone is wrong, the clock will be wrong too.
The instrument clock operates in UTC, therefore a correct time zone attribution is essential. Check
whether the time zone entry is correct before modifying the clock. Otherwise a wrong time setting
could be involuntarily programmed
