Reinforced connecting cables
As an option, Hauser can also deliver reinforced connecting cables with an additional,
reinforcing metal braid. Reinforced connecting cables should be used when laying the cable directly
in the ground, if there is a risk of damage from rodents or if using the measuring device below IP 68
degree of protection.
Operation in zones of severe electrical interference:
The measuring device complies with the general safety requirements in accordance with EN 61010
and the EMC requirements of IEC/EN 61326.

Caution!
Grounding is by means of the ground terminals provided for the purpose inside the connection
housing. Ensure that the stripped and twisted lengths of cable shield to the ground terminal are as
short as possible.
