Installing option modules
￭
Mechanical installation of I/O extension, fieldbus adapter and pulse
encoder interface modules
See hardware description for the available slots for each module. Install the option
modules as follows:
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur.
1. Stop the drive and do the steps in section Electrical safety precautions (page 21)
before you start the work.
2. Open the door of the auxiliary control cubicle (ACU).
3. Remove the shrouding at the top of the cubicle.
4. Locate the inverter control unit (A41).
5. Insert the module carefully into its position on the control unit.
6. Fasten the mounting screw.
Note: The screw secures and grounds the module. It is essential for fulfilling the
EMC requirements and for proper operation of the module.

Installation of an FSO safety functions module onto BCU
WARNING!
Obey the safety instructions of the drive. If you ignore them, injury or
death, or damage to the equipment can occur.
This procedure describes the installation of an FSO safety functions module onto the
BCU control unit. As an alternative, the FSO module can be installed adjacent to the
control unit, which is the standard method for factory-installed FSO modules. For
instructions, refer to the applicable FSO module user's manual.
1. Stop the drive and do the steps in section Electrical safety precautions (page 21)
before you start the work.
2. The FSO module comes with alternative bottom plates for installation onto
different control units. For installation onto a BCU control unit, the mounting
points should be located at the long edges of the module as shown in the
illustration below. If necessary, replace the bottom plate of the FSO module.
