Installing an FI5001 wind sensor - cable connection waterproofing

[QueenJane]

When installing an FI5001 wind sensor, the installation manual shows the cable assy. connection to the sensor with a loop (to prevent stress and maybe also as a drip loop) - but my question is why doesn't the manual recommend to wrap the connectors in shrink tubing?

Is this a good idea?

Are these connectors are already IP68 rated, so there is no need for shrink tubing?

Thanks.

It's a good idea to wrap any connections with exposure to the elements as a standard installation practice.
