WARNING!
Input and output connectors are not watertight until mated. Open connectors should be mated to
each other or plugged with appropriate watertight caps.
Les connecteurs d’entrée et sortie ne sont pas étanches jusqu'à ce qu’ils soient accouplés. Les
connecteurs doivent être accouplés ou fermés avec des terminaux étanches.
