6. SAFETY FOR THE CONNECTIONS
DANGER!
This warning indicates the possible
presence of voltage exceeding 1kV
(even for short periods) on the ter-
minals.
WARNING!
Electrical instrument connections
must be carried out by skilled tech-
nicians who are aware of the risks of
voltage presence. Before making any
connection, check if:
1. the instrument is grounded, following the pro-
cedure indicated in section 7.1
Warning! Each break or separation of the pro-
tection conductor on the inside or outside of
the instrument may jeopardise the operator’s
safety! Intentional breaking of the conductor is
strictly forbidden!
2. no voltage is in the lead wires.
3. the instrument is connected according to the
proper diagram (see section 7.6)
4. the power supply corresponds to the values on
the instrument label.
5. the instrument has been installed in a location
with no vibrations and with a suitable temperature
(see section 5.1).
6. once connected, the terminals are no longer
accessible.
7. the wiring is carried out in accordance with
the standards in force in the country where the
instrument is to be installed.

8
ENGLISH
8. an isolator and two over-current devices (eg.
fuses) are installed between the instrument and
the electrical system.
9. the connections are made respecting the
polarities (the instrument makes bi-directional
measurements)
Important: L1 of the voltage input = L1
of the current input
10. input and output polarities are respected when
voltage or current transformers (PT / CT) are
installed.
11. the connectors are fixed in such a way that they
cannot be accidentally detached.
7. ELECTRICAL CONNECTIONS
The connections are made on the back of the instru-
ment acording to the following order:
European version
USA version

ENGLISH
RS232 RS485
WARNING!
Before making any connections, che-
ck if the main control panel switch
is OFF.
1. Digital outputs. See section 7.4
2. Serial port. See sections 7.2 and 7.3
3. Slot available for optional boards. See section 7.5
4. Voltage inputs.See section 7.6
5. Current inputs. See section 7.6
6. Power supply. See section 7.7
7. Grounding. See section 7.1
7.1 Grounding
Connect the grounding cable and tighten the
screw. For direct current application, take care not
to connect the ground with the negative pole of the
power supply.
7.2 Rear Serial Port
The REAR serial port allows a connection with a
printer or a PC.
REAR port can also be configured as RS232 or
RS485 by means of the dip-switches shown in the
following illustration.
CONNECTIONS DIP SWITCHES
PIN 3 2 1 4 3 2 1
RS232 Gnd Tx Rx ON OFF ON OFF
RS485 + - COM OFF ON OFF ON
7.2.1 RS232
The RS232 interface allows connection between just
one instrument and a PC or other device.
The maximum recommended length for a connection
of this type is about 5 m.

10
ENGLISH
For the connection, uses a shielded cable with 3
conductors with a female DB9 or DB25 connector,
according to the following chart.
Terminal DB9F DB25F
Pin 1 - Rx Pin 3 - Tx Pin 2 - Tx
Pin 2 - Tx Pin 2 - Rx Pin 2 - Rx
Pin 3 - GND Pin 5 - GND Pin 7 - GND
Link pins 7 - 8 Link pins 4 - 5
Link pins 1 - 4 - 6 Link pins 6 - 8 - 20
The shield must be grounded only in one point.
7.2.2 RS485
The easiest and cheapest way to connect different
measuring devices in a network is the RS485 serial
line.
The RS485 standard interface allows a multi-
point connection. Between PC and the network,
it is required a Serial RS232 to RS485 Converter
(CV3285M).
If more than 32 instruments are to be connected,
insert a signal repeater (e.g. RPT85).
Each repeater can manage up to 32 instruments.
For the connection among the different modules, use
a cable with a twisted pair and a third wire.

11
ENGLISH
When there are strong electromagnetic distur-
bances, which may affect communication, a shielded
cable should be used.
The Rt termination resistance must be installed on
the PC and the last instrument connected along the
line. Thanks to these resistances, the reflected signal
along the line is reduced.
For a typical telephone pair, Rt can have values from
120 to 150 Ohm.
NOTE
The value of each resistance must not
be lower than 120 Ohm in order to avoid
an overload of line drivers.
The maximum recommended distance for a connec-
tion is 1200 m at 9600 Baud. For longer distances,
lower Baud Rates or low-attenuation cables or signal
repeaters are needed (RPT85).
7.3 Front Serial Port
A RS232 serial port connector is located in the upper
front part of the instrument.
It can be used to read the measurements, program
the instrument and transfer the recorded data to the
processing software (optional, see section 7 in the
Use and Programming manual).
To enable the communication, make the connections
using a standard DB5F-M serial cable, and select
FRONT serial port, as described in section 8.6 of
this manual.
The type of connection, shown in the following
picture, uses a third conductor to ensure that all the
devices on the network have the same reference
level and improve the reliability of communication.

12
ENGLISH
7.4 Digital Outputs
The basic instrument is equipped with two digital
outputs. Additional (input and / or output) boards can
be installed, on request, in the four available slots.
Standard single or multi-conductor cables can be
used for short-distance electrical connections.
For longer distances, the signal and power cables
must not be routed together.
If the signal and power cables cross, keep a 90° an-
gle to minimise the influence of the magnetic field.
ATTENTION!
Before inserting or removing the digital
output connector, make sure that the
instrument is not powered. The power
supply line, the measurement inputs
and any other voltage source must be
electrically disconnected.
7.4.1 Digital Output Connection
The digital outputs can be used, for example, to drive
alarm indicators or for pulse emissions. The needed
function is programmed through instrument setup.

7.6 Voltage and Current Inputs
Connect the voltage inputs by means of the supplied
4-pin connector. For current inputs, use the 6-pin
connector, to be fastened with the provided screws.
The following diagrams show some connection
examples.
WARNING!
Before switching ON the power, check if:
1. the 6-pin current connector is fastened with
screws.
2. in case of bi-directional measurements, the con-
nections are made respecting the polarities to
obtain correct values.
3. the connections are made according to the
diagrams in the following section, respecting the
cyclic order of phases. Important: L1 of the
voltage input = L1 of the current input.
4. input and output polarities are respected when volt-
age or current transformers (PT / CT) are installed.
5. the amperometric signal connector is adequately
fastened to avoid accidental disconnection.
6. a current input is never disconnected without prior
cutting off the load power supply.
If this is not possible, the secondary CT must be
short-circuited.
7. in case of three-phase measurements, all
parameters are shown only with the 3-phase,
4-wires, 3-CT wiring mode. In all other cases the
parameters without sense will not be displayed. By
wiring 3-wire,3-CT (without neutral) it is possible
to connect the N terminal to the ground. In such
a case it is possible to select the wiring 4-wire,
3CT displaying all parameters. It is recommended
an efficient ground to reduce the measuring error.
This suggestion cannot be applied for IT systems,
which are not referred to the ground.
