Mechanical installation of an FSO-xx safety functions module
This procedure describes the mechanical installation of an FSO-xx safety functions
module onto the inverter control unit. (The FSO-xx can alternatively be installed beside the
control unit, which is the standard with factory-installed FSO-xx modules. For instructions,
see the FSO-xx manual.)
1. Fasten the module onto slot 3 of the inverter control unit (A41) with four screws.
4. Tighten the FSO-xx electronics grounding screw.
Note: The screw tightens the connections and grounds the module. It is essential for
fulfilling the EMC requirements and for proper operation of the module.
5. Connect the FSO-xx data cable between FSO-xx connector X110 and BCU-x2 connector
X12.
6. To complete the installation, refer to the instructions in the User’s manual delivered with
the FSO-xx.
