Note!
• When mounting the adapter directly on the field device, use the twin-core cable included in the
delivery. You can use a commercially available instrument cable for remote mounting. If severe
electromagnetic interference can be expected from machines or wireless devices, for instance, we
recommend the use of a shielded cable.
• Connect the shielding in accordance with local regulations. With regard to the shielding
connection, no special requirements must be met for the WirelessHART Adapter.
