CSM_XW2R_DS_E_2_1
Many Variations in Connectors and
Number of Poles
• Models available with Phillips screw, slotted screw, push-in, or
e-CON connections.
• The terminal arrangement enables smoother wiring work.
• Push-in terminals simplify wiring and make the Terminal Blocks
even easier to use. (In comparison to the OMRON XW2F.)
• Mounting to DIN Track is possible.

Wire Preparation
3. Insert a flat-blade screwdriver
into the release hole and
gently reset the lever. You
should hear the operation
lever reset.
Use the strip gauge on the
front panel and strip 7 to 8 mm
of the insulation. If you use
stranded wires, twist them
several times.

4. Finally, check the following items.
• Make sure the operation lever has been
reset.
• Check the items given in step 2 again.
(Pull lightly on the wire to see if it is held
firmly in place.)

Disconnection Procedure
1. Press in the operation level, confirm
that the operation lever is locked into
place, and then pull out the wire.
2. After you remove the wire, always
reset the operation lever. However, if
you are going to connect another wire
to the same terminal, you do not need
to reset the operation lever and can
immediately connect the other wire.

Safety Precautions
Precautions for Correct Use
Wiring Precautions
• Do not perform wiring work, remove connectors, or connect connectors while power is being supplied.
Electric shock or damage to the device may result.
• Double-check all wiring before turning ON the power supply.
• After wiring, route the cable so that force is not applied directly to the connections.
Wires for Terminal Blocks
• Do not damage the cores when stripping the insulation from them.
• Always twist stranded wires together before connecting them.
• Do not presolder wires. It may not be possible to connect them or remove them.

Precautions for Safe Use
• Do not press the flat-blade screwdriver straight into the release hole. Doing so may break the terminal block.
• When you insert a flat-blade screwdriver into a release hole, press it down with a force of 30 N max. Applying excessive force may damage the
terminal block.
• Do not tilt or twist the flat-blade screwdriver while it is pressed into the release hole. Doing so may break the terminal block.
• Make sure that all wiring is correct.
• Do not bend the cable forcibly. Doing so may sever the cable.
