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
• If using the device below IP68 degree of protection
Operation in zones of severe electrical interference
The measuring system meets the general safety requirements →  159 and EMC
specifications →  138.
Grounding is by means of the ground terminal provided for the purpose inside the
connection housing. The stripped and twisted lengths of cable shield to the ground
terminal must be as short as possible.
