￭ Installation of an FSO-xx safety functions module onto BCU
WARNING!
Obey the instructions in chapter Safety instructions. If you ignore them,
injury or death, or damage to the equipment can occur.
This procedure describes the installation of an FSO-xx safety functions module onto the
BCU 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. Stop the inverter unit and do the steps in section Electrical safety precautions (page 17)
before you start the work.
2. The FSO-xx comes with alternative bottom plates for mounting on different units. For
mounting on the BCU, the mounting points should be located at the long edges of the
module as shown. Replace the bottom plate of the FSO-xx if necessary.
3. Fasten the FSO-xx onto slot 3 of the BCU control unit [A41] with four screws.
