Connecting The Transmitter; Protective Ground Connection - Endress+Hauser Proline Prosonic Flow 93 Brief Operating Instructions

Proline Prosonic Flow 93
5.1.2 Grounding Prosonic Flow P DN 15 to 65 (½ to 2½")
The Prosonic Flow P DN 15 to 65 (½ to 2½") is grounded via the cable gland.
Procedure
1. Guide the connecting cables through the cable gland.
2. Position the connecting cables in such a way that the heat shrink tube ends at the edge of
the cable gland (the stripped part of the connecting cable is thus in the correct position).
3. Tighten the nut of the cable gland (this twists the pins in the cable gland against the
shielding of the connecting cable and establishes grounding).
5.1.3 Cable specification for connecting cable
Only use the connecting cables supplied by Endress+Hauser.
Operation in areas with strong electrical interference
The measuring system complies with the general safety requirements in accordance with
EN 61010, the EMC requirements of IEC/EN 61326 "Emission as per Class A requirements"
