As an option, E+H 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 and NE 43.

Caution!
Grounding is by means of the ground terminals provided for the purpose inside the con-
nection housing. Keep the stripped and twisted lengths of cable shield to the terminals
as short as possible.
