    FSO-21 safety functions module (option +Q972) for the Prevention of unexpected start-up (POUS) safety function. ABB installs the FSO modules to the inverter units and sets default parameter values for the option at the factory. The user installs and wires an operating switch and an indication lamp (optional) on site.

  • Page 12: Summary Of Wirings And Settings

    The digital output of the FSO module to which the POUS indication lamp is connected, is selected as the output for the POUS completed signal. This is an FSO module parameter that ABB sets at the factory. The user must check the setting at the start-up. Additional wirings when safety pulse encoders are used: •...

    27, 28, 29, 30 There is a separate user interface (terminal block [X957]) inside the cabinet. ABB installs the FSO module and the wirings between the FSO modules and the inverter units at the factory. The FSO module has double terminals for the connection of the POUS switch.Wire the POUS switch to the appropriate terminals in the extension terminal block [X68].
