Power supply of the instrument
Supply voltage: 24V cc, 5W
12-pole terminal block connection, 5.08 mm pitch
 The instrument is powered through terminals 1 (+ 24 V DC) and 2 (0).
 The power cable must be channeled separately from other power cables with different volt-
ages, from the load cell cables and the logic input / output cables.

The instrument is of insulation class II (double insulation) and the ground is not provided on
the terminals. The groudning is still necessary to connect the cable shields, therefore check
that there is a valid electrical protective grounding.
Connection of the load cell
 The cell cable must not be channeled with other cables (e.g. outputs connected to remote
switches or power cables), but must follow its own path.
 Any cell cable extension connections must be carefully shielded, respecting the color code
and using the cable of the type supplied by the manufacturer. The extension connections
must be made by welding, or through support terminal blocks or through the junction box
supplied separately.
 The cell cable must have a number of conductors not higher than those used (4 or 6). In
the case of 6-conductor cable, of which only 4 are used (power supply and signal), connect
the reference wires to the respective polarity of the power supply wires .
!
A maximum of up to 6 350 ohm cells can be connected in parallel to the instrument. The supply voltage of
the cells is 5 V DC and is protected against temporary short circuit. The measuring range of the instrument
allows the use of load cells with sensitivity from 1 mV / V to 3.9 mV / V.
