The voltage to be applied is given by the following formula:
V = (R-250) x 0.027
(Eg. with an impedance of 1 ohm, the voltage to be applied
is:
(1000-250) x 0.027= 20.25 Vdc
For loads with impedance less than or equal to 250 ohms follow the diagrams below.
For loads with higher impedance of 250 ohms it is necessary to include in series an
external power supply.

SAFETY
This instrument was manufactured and tested in compliance with IEC 61010-1 CAT III -
300V class 2 standards for operating voltages up to 300 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 qualifi ed, 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 damaged.
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.
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 identifi ed 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 outputs and the options operate at low voltage level; they cannot be powered by
any unspecifi ed external voltage.
• The application of currents not compatible with the current inputs levels will damage
to the instrument.

NOTE n.3
NORMALE Classic Alarm with reference to a fi xed threshold or to maximum and
minimum delay and applicable hysteresis. “AVG” parameter is not used.
1-OF-3 Consider also the 2 following registers of the selected one in “MEAS”.
Works on a fi xed max or min threshold with delay and applicable
hysteresis. If one of the three register exceed the threshold the alarm goes
on. “AVG” parameter is not used.
3-OF-3 Consider also the 2 following registers of the selected one in “MEAS”.
Works on a fi xed max or min threshold with delay and applicable hysteresis.
When all the three register exceed the threshold the alarm goes on. “AVG”
parameter is not used.
DERIV “THRE” parameter becomes a % value, “AVG” parameter is used. The
instant value applied to the alarm on “MEAS” is compared with its value
mediated obtained on the basis of the time set on “AVG”. When the
instantaneous value combined alarm differs in more (setting “Max”) or less
(setting “MIN”) from the average value (“ AVG “) of the percentage set on
“THRE” the alarm goes on. With delay and applicable hysteresis.
UNBAL Consider also the 2 following registers of the selected one in “MEAS”.
“THRE” parameter becomes a % value. Alarm goes on when one of the
three register is different from the percentage set on “THRE” comply with
the higher value of the three read register if “MAX” is set on “TYPE”, or
comply with the lower value of the three register if “MIN” is set on “TYPE”
With delay and applicable hysteresis.
NOTE n.4
MAX Alarm setting in excess compared with the established conditions.
With the exception of “UNBAL”.
MIN Alarm setting in decrease compared with the established conditions.
With the exception of “UNBAL”
NOTE n.5
MEAS Indicates which register (and thus measure) the alarm is related.
See table n.1 input register.
THRE Alarm threshold in absolute value, with the exception made for “DERIV”
and “UNBAL” in which the value inserted becomes a percentage.
NOTE n.6
AVG Parameter to be used only in “DERIV” mode. Is the duration of the refe-
rence (in seconds) used to create a reference value for the istantaneous
readings.
NOTE n.7
NORMAL Physical output of the alarm excited during the duration of the alarm. It
restores automatically
HOLD Output remains excited until manual reset made via Modbus
PULSE-L Output generate a 500ms impulse when the alarm goes on.
PULSE-S Output generate a 100ms impulse when the alarm goes on.

The instrument is fi tted with a separate power supply. The power supply terminals are
numbered (17 e 18). Use cables with max cross-section of 2,5 mm2 if stranded, 4 mm2 if
rigid.
POWER SUPPLY AND SERIAL LINE CONNECTION
Voltage connection: Use cables with max cross-section of 2,5 mm2 if stranded 4 mm2 if rigid and connect them to the clamps marked VOLTAGE INPUT on the instrument according to
the applicable diagrams that follow.
Current connection: It is necessary to use external CTs with a primary rating adequate to the load to be measured and with a 5A or 1A secondary rating. Connect the CT output(s) to
the terminals marked I1, I2, I3 (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 mm2 if stranded and 4 mm2 if rigid.
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.
Scrupulously respect the matching of phase between the voltage signals and current signals (RTD) and the direction of insertion of CT (P1-P2 and S1-S2). Failure to comply with this
correspondence and connection diagrams gives rise to measurement errors. (*) The grounding of S2 must be close to the CT and not near the instrument.
