Direct connection
This method must be adapted depending on the diameter of wire used.
In the case of small-diameter wire (0.4mm²), the previous method is the most reliable.
After having prepared the wire, pinch it at more or less 12 mm from the end, and insert it in the connector.
3.7 BOOT
This signal must NOT be connected, NOT used. The use of the BOOT function is strictly

The use of the BOOT signal must be done through a transistor assembly or via dry contact.
The integrator has the responsibility to protect the input from electrical perturbations and to
respect the functioning parameters values.
