AGRITHERM T5 - electrical connections
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.
