Safety Precautions
Precautions for Correct Use
● Wiring
• Always turn OFF the power supply before wiring.
Otherwise, cables or other conductors can short the
terminals and cause the Unit to fail.
• Do not connect or disconnect Connectors with the power
turned ON. Otherwise, it may cause malfunctions.
● Wiring Terminal Blocks
• Direct Wire Connections with a Terminal Block with M3
Screws
1. Use a wire size between 0.3 and 1.25 mm2 (AWG22 to
AWG16).
2. Prepare the end of each wire as shown in the following
diagram.
● Terminal Screw Tightening Torque
• Select a tightening torque from the following table when
connecting wires or crimp terminals to the terminal block.
Terminal Block
Tightening torque
N⋅m
With M3 screws
0.40
With M3.5 screws

● Mounting Units to and Removing Units from DIN Track
• For terminal blocks with M3 screws, use a flat-heat
screwdriver like the one shown in the following diagram.
2.9- to 3.5-mm blade
6 mm
Screw slot width: 0.7
3. The wire insertion holes are 1.8 × 2.5 (H × W) mm on the
terminal block with M3 screws.

• XW2B Connector-Terminal Block Conversion Units can be
mounted side-to-side on DIN Track. The flanges for
mounting screws are located on each side at the bottom of
the XW2B.
• Secure both ends of the XW2B with End Plates.
• When removing the Unit from a DIN Track, insert a flat-head
screwdriver into the slider and pull the lock out.
