Signal Cable Termination
Solderless Lug
• Cable termination
Use solderless lugs for all the RIO I/O signals that are wired by terminal connection.
• Solderless lug specifications
The specifications of the solderless lug to use are determined by the nominal cross
sectional area of the power cable for which the lug is to be used, the lug screw, dimensions
and so on.

IMPORTANT
• For CENTUM CS 3000, spring lugs are used for connecting signals for RIO and for
connecting the RIO bus.
• Always use solderless lugs with insulated covering.
• Always use solderless lugs and crimp-on tool manufactured by the same manufacturer.
• The crimp-on tool must be matched to the wire thickness.
