Contents of this chapter
This chapter describes the wiring of the safety option done at the factory and contains
guidelines for making user connections (if any).
Wiring
There is an extension terminal block [X68] for the connections to the FSO module inside
the drive cabinet. The FSO module connectors [X113] and [X114] have been wired to [X68].
The tables below show the connections between the extension terminal block and the FSO
module.

X68
There is a separate user interface (terminal block [X965]) inside the drive cabinet.
ABB installs the FSO and FSE-31 modules and the wirings between the FSO module and
the user interface at the factory.
The user must wire the safety pulse encoder to the FSE-31 module on site. Obey the
instructions of the encoder manufacturer as well as the following rules:
•
Use a double-shielded, twisted pair cable.
•
The maximum allowed cable length between the safety pulse encoder and the FSE-31
module is 300 m (980 ft).
