a = signal cable, b = coil current cable (cross-section: max. 2.5 mm

)

1 = core, 2 = core insulation, 3 = core shield, 4 = core jacket, 5 = core strengthening,

6 = cable shield, 7 = outer jacket

Optionally, Endress+Hauser also supplies reinforced connecting cables with an additional, metal strenghtening

braid. We recommend such cables for the following cases:

• Cables laid underground

• Danger of rodent attack

• Device used with ingress protection IP 68

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.

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.
