Reinforced connecting cables
As an option, Endress+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 (NEMA 6P) standard 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.
