Installation of the instrument

The following procedures must be performed by specialized personnel

All connections must be made with the instrument switched off

Do not install the instrument near power equipment (motors, inverters, contactors, etc.) or
equipment that does not comply with EC standards for electromagnetic compatibility.

A network switch must be provided near the instrument in order to be able to remove the
power supply at any time.

The RS232 serial line must have a maximum length of 15 meters (EIA RS-232-C stand-
ards)
Power supply of the instrument

The instrument is powered through the power supply cable.

The power supply cable must be channeled separately from other power cables with dif-
ferent voltages, from the slots of the load cells

Supply voltage: 100 – 240 V
∼
50/60 Hz 20 VA
Connection of the load cell

The cell cable must not be channeled with other cables (e.g. outputs connected to contac-
tors or power cables), but must follow its own path.

Any extension connections of the cell cable must be shielded with care, respecting the color
code and using the cable supplied by the manufacturer. The extension connections must
be made by welding, or through support terminal boards or through the junction box sup-
plied separately.

The cell cable must have a number of wires no greater than those used (4). In the case of
a 6-wire cable, connect the reference wires to the respective polarity of the power supply
wires.
Up to a maximum of 8 350 Ohm cells in parallel can be connected to the instrument. The cell supply voltage
is 5Vdc and is protected against temporary short circuit. The measuring range of the instrument foresees the
use of load cells with a sensibility from 1 mV/V to 3.9 mV/V.
