Ferrules and
Solid Wires
If a wire is difficult to connect because it is too thin, use a flat-blade
screwdriver in the same way as when connecting stranded wire.
Connecting Stranded Wires
Use the following procedure to connect the wires to the terminal block.
1. Hold a flat-blade screwdriver at an angle and insert it into the
release hole. The angle should be between 10° and 15°.
If the flat-blade screwdriver is inserted correctly, you will feel the
spring in the release hole.
2. With the flat-blade screwdriver still inserted into the release hole,
insert the wire into the terminal hole until it strikes the terminal
block.
3. Remove the flat-blade screwdriver from the release hole.

Checking Connections
• After the insertion, pull gently on the wire to make sure that it will
not come off and the wire is securely fastened to the terminal block.
• To prevent short circuits, insert stripped part of a stranded or solid
wire or the conductor part of a ferrule until it is hidden inside the
terminal insertion hole. (See the following diagram.)
