Sto Cable And Data Cable Between Fso Module And Drive; Power Supply Connection/Cables; Ensuring The Emc Compatibility; Selecting Control Cables - ABB FSO-12 User Manual

Note: You can use calculation software to assist in selecting the appropriate
architecture that will meet the safety integrity requirements for a particular application.
Use, for example, ABB's Functional safety design tool, see Functional safety design
tool user's manual (3AXD10000102417 [English]).



Power supply connection/cables

The system must be protected against over-voltage and over-current.
The length of the cabling between the FSO and its power supply must be
three meters or shorter, or a sufficiently low interference level must be otherwise
guaranteed.
Note: The 24 V DC power supply should be equipped with a supply disconnecting
device to enable an easy start-up of the FSO module.
Note: The FSO module power input (X112) is protected against over-voltage, under-
voltage and over-current, and it has a reverse polarity protection. FSO module enters
Fail-safe mode if any of these protections trip. The module enters Fail-safe mode also
if output voltages of the internal power supply are outside specified limits due to
supply input over-voltage.
Note: If you de-energize the FSO module, you cannot operate the drive.


Ensuring the EMC compatibility

The system must only be used in the EMC environment it is designed for, or
necessary mitigations must be applied.


Selecting control cables

For the control cables to on-field devices, it is recommended that shielded cabling is
used. Double-shielded cable is the best alternative for low-voltage digital signals but
single-shielded twisted multi-pair cable is also usable.
