1) Before connecting the instrument to the supply,
make sure that the line voltage corresponds to
that indicated on the rating plate.
2) To avoid electric shock, connect the power line at
the end of the wiring procedure.
3) For supply connections use No 16 AWG or larger
wires rated for at least 75°C.
4) Use copper conductors only.
5) Do not run input wires together with power line
cables.
6) For 24 V AC/DC the polarity does not matter.
7) The power supply input has NO fuse protection.
Please, provide a T type 1A, 250 V fuse externally.
8) The safety regulations for equipment
permanently connected to the mains require
that there is a switch or circuit breaker in the
building electrical system and that this:
- is near the device and can easily be reached by
the operator;
- is marked as the device ON/OFF device.
NOTE NOTE NOTE NOTE NOTE: A single switch or circuit-breaker can drive
more than one instrument.

These instruments can detect the opening of the
input circuit (TC or RTD). This failure is displayed
as an overrange condition.
For the thermocouples only one can select, by
means of jumpers SH1 and CH1 indicated in Fig.
9, the type of indication to be obtained when the
thermocouple is open (see table at the bottom of
the page).
To gain access to the jumpers the instrument
must be taken out of its case.
