Reinforced connecting cable
Use in the following situations:
• When laying the cable directly in the ground
• Where there is a risk of damage from rodents
Operation in zones of severe electrical interference
The measuring system meets the general safety requirements (
Grounding is by means of the ground terminal provided for the purpose inside the connection
housing. The stripped and twisted lengths of cable shield to the ground terminal must be as short
as possible.
