3. Cable connections
The wind sensor is supplied with 2 metres fixed cable. From factory,
the cable is connected to the sensor via a waterproof gland, and this
must not be replaced by another cable. The cable can be extended by
using the connection box kit or the IP67 connector kit (both optional).
In order to protect the wind sensor and the personnel in the best
possible way from lightning strokes, use a lightning rod installed with
the tip at least one metre above the wind sensor. The lightning rod
must be properly grounded in compliance with all applicable safety
regulations. The wind sensor cable screen and the extension cable
screen must be connected.
For further protection of the cable between the wind sensor and the
connection box, as well as the installation cable between the
connection box and the interface box, it is recommended to use a
metal conduit pipe. If the instrument is installed in a metal panel, this
panel has to be carefully earthed, as well as the instrument itself.
Suitable extension cable is available from DEIF. Alternatively, an
installation cable, for example UL2464 1 AE, 4 × 0.75 mm
2
screened, can be used. The maximum length is 300 m, and maximum
70 nF capacity between the signal conductors.
