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
2
(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.
Probes have no connection polarity and can be extended using a normal bipolar cable (note that the extension
of the probes influences the electromagnetic compatibility - EMC - of the instrument: take great care with the
wiring).
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.
