Safety Precautions
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.
3. The wire insertion holes are 1.8 × 2.5 (H × W) mm on the
terminal block with M3 screws.
Direct Wire Connections with a Terminal Block with M3.5
Screws
(With a Terminal Block with M3 Screws)
Note: Round rod and blade crimp terminals are made by Nichifu.
Terminal Screw Tightening Torque
Select a tightening torque from the following table when
connecting wires or crimp terminals to the terminal block.
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.
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.
