General wiring instructions
1. For the STO circuit wiring, use the type of cable specified in the
applicable drive or inverter unit hardware manual. With an FSO
module, use the STO cable that is included in the FSO module
delivery.
2. Install only the sensor circuit into the potentially explosive
atmosphere.
The sensor circuit in the Ex Zone must comply with the
requirements for the applicable type of protection, such as:
•
Ex d (EN/IEC 60079-1)
•
Ex eb (EN/IEC 60079-7, Ex e in EN 60079-7:2007 and IEC
60079-7:2006)
•
Ex ec (EN/IEC 60079-7, Ex nA in EN/IEC 60079-15:2010).
3. Install the drive or inverter unit, 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
