TERMS OF WARRANTY
The warranty is valid 3 years starting from the manufacturing date, as evidenced on the receipt
of the calibration certificate, for the period indicated on the package.
The warranty covers the free repair or substitution of equipment parts which are recognized as
faulty due to manufacturing defects.
The warranty does not cover those parts which result defective due to negligent or improper use,
incorrect installation or maintenance, operation by unauthorized personnel, damage during
transportation, or which in any case do not indicate manufacturing defects of the equipment. Also
excluded from the warranty are technical interventions regarding the installation of the equipment.
Also excluded from the warranty are technical interventions regarding the installation of the
equipment to the electrical system.
The manufacturer declines any responsability for eventual injury or damage to persons, animals
or things as result of failure to follow the instructions in the Instructions Manual or caused by
improper use of the equipment.
The warranty covers equipment returned ex works. The expenses of transport as well as the relative
risks of same, both to and from the place of repair, will be the sole responsability of the User.
This warranty expires after the date of purchase and any assistance required after said date
including spare parts, labor, transport of personnel and materials will be charged to the User
basated on the tariffs in force for Technical Assistance Service at the time of such requested service.
In any case the substitution of the equipment as well as the extension of the warranty after such
breakdown is excluded.
The packaging of each instrument bears a "CE" mark of conformity.

SAFETY
This instrument was manufactured and tested in compliance with class 2 IEC EN61010 and VDE
411 standards, in accordance with group C VDE 0110 standards for operating voltages up to 500
VACrms. Quality and accuracy are guaranteed by an ISO9000 certified production structure
which utilizes the latest surface mounting techniques, therefore the instrument left the factory in
perfect condition regarding technical safety.
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 beginning installation, check that it is still intact and no
damage was incurred during transport.
Before mounting, ensure that the operating voltage and mains voltage set are the same, and then
proceed with installation.
The instrument unit is double insulated and does not require an earth connection. The power supply
must be connected to phase and neutral as shown in the relevant diagram.
A 50 mA T type HBC fuse should be installed in the power supply circuit to the instrument.
The power supply must be connected before the measurement circuit.
Before any maintenace and/or repairs, whenever the instmrument must be opened, it must be
disconnected from all power sources.
The instrument’s capacitors may still be charged even after it has been disconnected from all
power sources.
Maintenance and/or repairs must be carried out only by qualified, authorized personnel.
If there is ever the suspicion that safe use is no longer possible, the instrument must be taken out
of service and precautions taken against accidental use.
Operation is no longer safe when:
- There is clealy visible damage.
- The instrument no longer functions.
- After lengthy storage in unfavorable conditions.
- After serious damage incurred during transport.
2.1
OPERATOR SAFETY

POWER SUPPLY
The instrument must have a power supply with voltage ranging from 200 ÷ 240 VAC 50/60 Hz
(100 ÷ 120 VAC 50/60 Hz is also available on request) using max. cable gauge 4 mm
2
and
attached to the power supply terminals (see Fig.1).
The instrument’s power supply does not need an earth connection.
The instrument requires the installation of an external 50 mA type HBC fuse in the power supply
circuit.
3.1
VOLTAGE MEASUREMENT CONNECTIONS
For the voltage measurement connection use wires with max gauge 4mm
2
. Insert the wires in
the screw terminals for the voltage measurement connection.
3.1.1 3 wires delta connection (

)
The diagram in Fig.2 indicate how to connect the terminals to the phases on unbalanced three-
phase systems without neutral (DELTA).
3.1.2 4 wires STAR CONNECTION (

)
The diagrams in Fig. 3 indicate how to connect the terminals to the phases on unbalanced three-
phase systems with neutral (STAR).
The detailed wiring diagrams to the network are given in chapter 3.
3.2
CURRENT MEASUREMENT CONNECTIONS
The instrument is equipped with three wire passages through which the current wires must be
passed without having to interrupt them. Insert the wires as indicated in Fig.4 (instructions as
to how to insert the current wire are also found on the instrument’s label in correspondence with
the wire passages). The P1 and P2 indications identify the correct direction of the current.
Wires with max. 7 mm external diameter are permitted.
Advanced Function:
If the instrument has been programmed for Cogeneration functioning, it
is absolutely essential that the sense (orientation) of the current direction be observed.
