ELECTRICAL CONNECTIONs

Attention! Make sure the machine is switched off before working on the electrical connections.
The instrument is equipped with screw or disconnectable terminal blocks for connecting electrical cables with a max.
diameter of 2.5 mm (one wire per terminal for power connections): for the terminal ratings, see the label on the instrument.

Do not exceed the maximum permissible current; in case of higher loads, use a suitably rated contactor.
Make sure the power supply voltage complies with that required by the instrument. NTC/PTC/PT100 probes have no
connection polarity and can be extended using a normal bipolar cable (Note that extending the probes burdens the
behaviour of the instrument in terms of EMC electromagnetic compatibility: specifically, if Pt100 probes with cable longer
than 3 mt are used, an extreme care must be taken during wiring operations).
Probe cables, power supply cables and the TTL serial cable should be routed separately from power cables.

CONDITIONS OF USE

Permitted use

For safety reasons, the instrument must be installed and used according to the instructions supplied and, in particular, parts
under dangerous voltages must not be accessible in normal conditions. The device must be adequately protected from
water and dust with regard to its application, and must only be accessible using tools (except for the front panel).
The device is suitable for use in household refrigeration appliances and/or similar equipment and has been tested for safety
aspects in accordance with the harmonised European reference standards.

Improper use

Any use other than that expressly permitted is prohibited. The relay contacts provided are of a functional type and subject
to failure: any protection devices required by product standards, or suggested by common sense for obvious safety
requirements, must be installed externally to the instrument.
