the Hardware Manual of the drive.
Mechanical installation
• Insert the RETA-02 into its specified slot in the drive (SLOT2 for 
ACS550, SLOT1 for ACS800).
• Fasten the two screws.
Electrical installation
• Connect the Ethernet network cable (RJ-45 connector) to the 
RETA-02 module. Standard CAT 5 UTP or STP cables can be
