Terminal Block Wiring Procedure
Spring-type connectors are used for SMARTSTEP Junior Servo Drivers. The procedure
for wiring these is described below.
CNA Connector
1. Remove the Terminal Block from the Servo Driver.
The Terminal Block must be removed from the Servo Driver before being wired.
The Servo Driver will be damaged if the wiring is done with the Terminal Block in place.
2. Strip the covering off the ends of the wires.
Prepare wires of the right sizes, according to the tables provided under
Terminal Block
Wire Sizes
above, and strip off 9 to 10 mm of the covering from the end of each wire.
9 to 10 mm
3. Open the wire insertion slots in the Terminal Block
There are two ways to open the wire insertion slots, as follows:
• Pry the slot open using the lever that comes with the Servo Driver (as in Fig. A).
• Insert a flat-blade screwdriver (end width: 2.5 to 3.0 mm) into the opening for Servo
Driver installation, and press down firmly to open the slot (as in Fig. B).
