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:
• There is clearly visible damaged.
• The instrument no longer functions.
• After lengthy storage in unfavorable conditions.
• 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.7
MODE 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 Considers also the 2 following registers of the selected one
in “MEAS”. It operates on a fi xed max or min threshold with
delay and applicable hysteresis. If one of the three registers
exceeds the threshold the alarm goes ON. “AVG” parameter
is not used.
3-OF-3 Considers also the 2 following registers of the selected one
in “MEAS”. It operates on a fi xed max or min threshold with
delay and applicable hysteresis. When all the three registers
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 diff ers 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 Considers 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 diff erent 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.
TYPE MAX Alarm setting in excess or in decrease compared with the
predefi ned conditions.
With the exception of “UNBAL and UNBAL%”.
MIN
MEAS Indicates which register (measure) the alarm is related to.
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 be-
comes a percentage.
NOTE n.8
HYST Hysteresis, ie the cycle between alarm value and alarm
return value. It is a particularly useful function to avoid
unwanted oscillations and / or alarms. Example: Alarm on
current set at 100 A Max with 5% hysteresis. The alarm is
activated at 100 A and is deactivated at 95 A
DEL Delay time (between 1 sec and 99 min) for activation.
Delay time (between 1 sec and 99 min) for deactivation.
AVG Parameter to be used in “DERIV” mode only. Moving window
width (in secs) used to create a reference value with which
to compare the instantaneous data
OUT NORMAL Alarm remains active during the duration of the event. It
restores automatically.
HOLD Alarm remains active until the manual reset via Modbus.
PULSE-L Generates a 500ms impulse when the alarm goes on.
PULSE-S Generates a 100ms impulse when the alarm goes on.

LAN 10/100 ETHERNET PORT
DIP-SWITCH CONFIGURATION
EXPBUS PORT
The instrument is equipped with a Ethernet Lan 10/100 Auto-MDI/MDIX
port.
For the connection can be used a data cable straight or crossover.
Note: the port is not a PoE (Power over Ethernet = device power supply
via the Lan port) type. The connection of the device to a PoE port is
anyway accepted. The power supply anyway must be always provided
by an external power supplier.
The ExpBus port, confi gurable via Ethernet port on web pages:
- uses a multicast communication rated at 250kb/sec with collision
management
- max cable length : 10 meters
- manages up to 16 modules (but technically can manage up to 126)
- uses the UTP cable, 4 wires used:
2 for the power supply at 9 Vdc
2 for the bidirectional communication
The modules will also power supply the ExpBus port
The cable must be connected in in-out modality (multidrop) as per the
RS485 Bus.
Use cables with max cross-section of 2,5 mm2 if stranded, 4 mm2 if rigid and connect them
to the terminals marked VOLTAGE INPUT on the instrument according to the applicable
diagrams that follow.
VOLTAGE CONNECTION CURRENT CONNECTION
Use only the CTs supplied with the instrument. Connect the CTs to the terminals marked
with I1, I2, I3, I4 (current input) according to the diagrams.
N.B. Failure to comply with the connection diagrams results in measurement errors. Do
not extend the CT cables.
The instrument is equipped with a separate power supply. The power supply terminals
are numbered (17) and (18). Use cables with max cross-section of 2,5 mm2 if stranded,
4 mm2 if rigid.
