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
• Danger of rodent attack
• Device used with NEMA 6P (IP 68) ingress protection
Operation in areas 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 con-
nection housing. Keep the stripped and twisted lengths of cable shield to the terminals
as short as possible.
