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 cables under
ground, in situations where there is the danger of cable destruction by rodents and if using a
measuring device with 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. Keep the stripped and twisted lengths of cable shield to the terminals as short as possible.
