5.2 WALL OR DIN RAIL MOUNTING VERSION “B/E”
• Installation must be only performed by qualified personnel and in accordance with local governing regulations.
• Make sure that the housing material is compatible with environmental conditions. In case of outdoor installation it is
recommended to protect the unit from the direct sunlight and from the rain.
• An improper use of the unit can cause serious injuries to operators and damages to the product and to the connected
equipments.

6.3 TERMINAL CONNECTION VERSION “B”
1) Separate the power cables of the Agritherm T5 from the signal cables
2) Remove the plugs of the cable glands and open the lid unscrewing the screws.
3) Insert the cables into the transmitter through the cable glands.
4) Close the lid and tighten the cable glands.
6.4 HUMIDITY INFILTRATIONS
In order to avoid humidity infiltrations inside the enclosure it is recommended:
- to use a cable with outer diameter of 6÷12mm and to fully tighten the M20 cable glands.
- to close the lid well
- to position the cable so that it forms a downward curve at the M20 output; in this way the
condensate and/or the rain water will tend to drip from the bottom curve.

7.2 TEMPERATURES DISPLAY
The temperatures detected by the probes are automatically and cyclically shown on the display.
The system automatically scrolls the pages every 20 seconds.
The values in yellow indicate that the average temperature has been exceeded and the values in red
indicate that the maximum temperature has been exceeded.
Scrolling notices (in yellow and red) indicate which probe is detecting a temperature alarm.
