3. Install the drive, including the components of the ATEX-certified

motor thermal protection function, outside the potentially explosive
atmosphere.

4. For the sensor connection, ABB recommends to use shielded

twisted-pair cable. This type of cable decreases electromagnetic
interference in the sensor circuit.

5. Route the sensor cables away from the motor cable. Power cables

can cause electromagnetic interference in the sensor circuit.

6. Ground all sensor cable shields to a single grounding point

outside the potentially explosive atmosphere. 360-degree
grounding of the cable shields at the cable entry of the drive is
recommended. Do not connect the cable shields to ground at the
sensor end of the cable.
