2 Safety
This instrument was manufactured and tested in compliance with IEC 1010 class 2 standards and in
accordance with VDE 0110 group B insulation 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 X3M-D and Flash-D 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 Wiring diagrams
4.1 Power supply
The instrument is fitted with a separate power supply with extended operating
range. The power supply terminals are numbered (10) and (11).
Use cables with max cross-section of 2,5 mm
2
.
4.2 Measurement connections
4.2.1 Voltage connection
Use cables with max cross-section of 2,5 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 2,5 mm
2
.
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 LEADS TO SEVERE MEASUREMENT ERRORS.

4.3 Outputs connection
The instrument is equipped with two opto-isolated transistor outputs rated 27 Vdc, 27 mA (DIN 43864
standards).
The outputs working mode is set by default to operate as pulse output proportional to the Active energy
(output 1) and to the Reactive energy (output 2). They support an output rate of 1.000 pulses per kWh (or
kvarh) referred to the instrument input range without any CT and PT multiplier.
In order to calculate the energy value of each pulse the following formula must be considered.
