Regulations
Electromagnetic compatibility: The device conforms to Directive 2004/108/EC
Safety: The device conforms to Directive 2006/95/EC
Food Safety: The device complies with standard EN13485 as follows:
- suitable for storage
- application: air
- climate range A
- measurement class 1 in the range from -25°C to 15°C
(exclusively using Eliwell NTC probes)
NOTE: The technical specifications given in this document regarding measurement (range, accuracy, resolution, etc.) refer to the
instrument and not to any accessories provided, such as the probes. This means, for example, that the error introduced by
the probe must be added to the typical error of the instrument.
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.
