Resolving Cable Length Concerns for PH 1 3 1711 in Hayward Sensor Units

Client:
Hi - it says the cable length of the PH 1 3 1711 is 5 metres - is that correct? If so that is much too long to fit in to the Hayward sensor unit.

Technical Advisor:
Hi, yes it is 5 m .just keep it rolled up and it works

Client:
Ok thanks Olivier
