• Cable outer diameter: 5 to 9 mm (0.2 to 0.35 in) depends on the used cable gland (see
technical information)

When operating via a handheld terminal or via a PC with an operating program, a minimum
communication resistance of 250 must be taken into account.
5.2.5 Shielding/potential equalization
• A normal device cable suffices if only the analog signal is used. A shielded cable is
recommended if using the HART protocol. Observe grounding concept of the plant.
• When using in hazardous areas, you must observe the applicable regulations.
Separate Ex documentation with additional technical data and instructions is included with
all Ex systems as standard. Connect all devices to the local potential equalization.
