Converter classication: class I, IP65 for housing in self-extinguishing pc / abs,
overvoltage category II, degree 2 of nominal pollution.
INPUTS / OUTPUTS INSULATION
Inputs * and outputs are isolated from each other up to 500V
The 4-20mA outputs, the digital outputs and the RS485 bus share the same 24V
references (they are not isolated from each other). Note *: 3V power supply for
using the battery inputs is not isolated.
The instrument is suitable for indoor and outdoor climatic conditions
Altitude: from -200m to 5000m
Humidity range: 0-98%, 0-85% without condensation (IP65)

The variations in the mains voltage must not exceed ± 10% of the nominal voltage.
Inputs and outputs are isolated from each other up to 500 V *.
** The 4-20mA output (optional) is electrically connected to the outputs ON / OFF and to
the supply voltage (24V ) of the outputs.
Version LV / LLV: inrush current <20A
Version HV : inrush current < 25A
* Isolation on the digital inputs is excluded using the battery power supply
** The 4-20mA outputs (optional) are electrically connected with the ON / OFF outputs, with
the supply voltage (24V) of the outputs and with the power supply of the RS485 network
(where present).

FRONT VIEW
All cables used for the connections must be of a shielded type; the screen
must be connected to the ground.
The length of the cables must be between 3m and 30m.
The ow measurement can be done in 2 ways:
analog: through a 4-20mA signal.
factorized volume pulses (frequency).
The temperature is measured by means of a pair of PT thermoresistances (RTD), preferably
with 4 wires (MANDATORY version for MID instruments); the selectable values are:
PT100, PT500 and PT1000.

ELECTRICAL CONNECTIONS POWER
Before connecting the power supply, check that the power supply voltage is within the
limits indicated on the nameplate.
For the connection use only approved cables with reproof properties.
The power supply line must be equipped with an external protection against over currents
(fuse or magneto thermal).
In close proximity to the instrument, install an easily accessible and clearly identied switch
to cut o the power supply.
If the PoE energy version, to guarantee the isolation required by IEEE for ethernet, the external
power supply must be protected at least 1500Vac with respect to a ground and any other
connection.
