Installing an FSO safety functions module (frame sizes R1i…R7i)
If you need to install multiple optional modules on the control unit, install the FSO
module first.
WARNING!
Obey the safety instructions given in ACS880 multidrives cabinets and
modules safety instructions (3AUA0000102301 [English]). If you ignore
the safety instructions, injury or death, or damage to the equipment
can occur.
If you are not a qualified electrical professional, do not do installation
or maintenance work.
1. Stop the drive and do the steps in section Electrical safety precautions (page 44)
before you start the work.
2. The FSO module comes with alternative bottom plates for mounting on different
control units. Replace the bottom plate of the FSO module if necessary.
3. Connect the data cable to connector X12 on the control unit.
4. Put the FSO module into its position on SLOT 2 of the control unit. Attach the
module by the bottom plate with four screws.
5. Torque the FSO module electronics grounding screw to 0.8 N·m (7.1 lbf·in).

7. To complete the installation, refer to the instructions in the user’s manual delivered
with the FSO module.
