Cable connection
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 is
extended by using a standard connection box or the optional IP67 connector kit for WSS.
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 installation 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.
Installation cable, e.g. UL2464 18AWG4C + AE, 4 x 0.75mm
2
screened, max. 300m, and max.
70nF capacity between the signal conductors. Suitable extension cable is available from DEIF.
