As an option, Hauser can also deliver reinforced connecting cables with an additional,
reinforcing metal braid. We recommend such cables for the following cases:
• Directly buried cable
• Cables endangered by rodents
• Device operation which should comply with the IP 68 standard of protection
Operation in zones of severe electrical interference
The measuring device complies with the general safety requirements in accordance with
EN 61010, the EMC requirements of EN 61326/A1, and NAMUR recommendation NE 21.

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.
