To ensure compliance with the safety standards, the electrical system must be fitted with a suitable switch or disconnector (compliant with standards IEC 60947-1
and IEC 60947-3), located near the appliance.
If the appliance is used in a manner that is not specified by the manufacturer, the protection featured for the appliance may be compromised and the appliance may be
seriously damaged.
Avoid assembling the controllers in environments with the following characteristics:
- relative humidity greater than 90% non-condensing;
- strong vibrations or knocks;
- exposure to continuous water sprays;
- exposure to aggressive or pollutant atmospheres (e.g. sulphur or ammonia fumes, saline mist, smoke) so as to avoid corrosion and oxidisation;
- strong magnetic and/or radio interference (for example, near transmitting antennae).
Observe the following warnings when connecting the controllers:
The incorrect connection of the power supply may seriously damage the system.
Use cable ends suitable for the corresponding terminals.
Loosen each screw and insert the cable ends, then tighten the screws and slightly tug the cables to check that they are sufficiently tight;
To tighten the screws, do not use automatic screwdriver, or alternatively adjust to a torque of less than 50 Ncm. If spring terminals are used, compress the spring
using a screwdriver, insert the stripped wire then release the spring and slightly tug the cables to check that they are sufficiently tight.
Separate as much as possible (at least 3 cm) the signal cables from the cables carrying inductive loads and power cables to avoid possible electromagnetic
disturbance.
Never insert power cables (including the electrical cables) and probe signal cables in the same conduits.
Do not install the probe cables in the immediate vicinity of power devices (contactors, circuit breakers or similar). Reduce the path of the probe cables as much as
possible, and avoid spiral paths that enclose power devices Remember that the NTC temperature probes do not have polarity, and therefore the order the ends are
connected is indifferent.
Cleaning the instrument.
When cleaning the instrument do not use ethyl alcohol, hydrocarbons (petrol), ammonia and derivatives.
Use neutral detergents and water.
