Precautions for Correct UsePrecautions for Correct Use
Always use the specified crimp tool to attach the crimp terminals. If a crimp tool is not used, the
cable will not be crimped properly, which may cause the cable to become detached from the ter-
minal.
The following crimp tools are available.
3 Connecting Cables
Use the following procedure to connect cables to the connection terminals.
(1) Orient the connector properly, and then insert the signal lines fully into the back of
each terminal hole in the connector, as shown in the following diagram. (The signal
lines are secured in this way, without requiring the use of a tool.) If crimp terminals
are not used on the signal lines, use a small flat-blade screwdriver to press down on
the orange tab to insert the signal lines.
