Reinforced connecting cables
Reinforced connecting cables with an additional, reinforcing metal braid should be used
for:
• When laying the cable directly in the ground
• Where there is a risk of damage from rodents
Operation in zones of severe electrical interference
The measuring system meets the general safety requirements (→  145) and EMC
specifications (→  130).
