Installing optional modules on the control unit
￭ Installing an FSO-xx safety functions module (frame sizes R1i…R7i)
In case you need to install multiple optional modules on the control unit, install the FSO-xx
first.
WARNING!
Read the safety instructions given in Safety instructions for ACS880
multidrive cabinets and modules (3AUA0000102301 [English]). 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 57) before
you start the work.
2. The FSO-xx comes with alternative bottom plates for mounting on different units. For
mounting on the ZCU-14, the mounting points should be located at the short edges of
the module as shown. Replace the bottom plate of the FSO-xx if necessary. For mounting
on the ZCU-12, the mounting points should be located at the long edges. Replace the
bottom plate of the FSO-xx if necessary.
3. Connect the data cable to connector X12 on the control unit.
4. Put the FSO-xx into its position on slot 2 of the control unit.
5. Tighten the FSO-xx electronics grounding screw to tightening torque 0.8 N·m.
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.
6. Attach the module by the bottom plate with four screws.
