ø22 XW Series Emergency Stop Switches
• Turn off power to the XW series emergency stop switch before start-
ing installation, removal, wiring, maintenance, and inspection of the
relays. Failure to turn power off may cause electrical shock or re
hazard.
• For wiring, use wires of the proper size to meet the voltage and
cur rent requirements. Tighten the M3 terminal screw to a tightening
torque of 0.6 to 1.0 N·m. Failure to tighten the terminal screws may
cause overheating and re.
Removing the Contact Block
First unlock the operator button. Grab the bayonet ring and pull back
the bayonet ring until the latch pin clicks
, then turn the contact block
counterclockwise and pull out
.

Notes for removing the contact block
1. When the contact block is removed, the monitor contact (NO contact)
is closed.
2. While removing the contact block, do not exert excessive force, oth-
erwise the switch may be damaged.
3. An LED lamp is built into the contact block for illuminated push-
buttons. When removing the contact block, pull the contact block
straight to prevent damage to the LED
lamp. If excessive force is exerted, the LED lamp may be dam aged
and fail to light.
Panel Mounting
Remove the locking ring from the operator. Insert the operator from
panel front into the panel hole. Face the side without thread on the
operator with TOP marking upward, and tighten the locking ring using
ring wrench MW9Z-T1 to a torque of 2.0 N·m maximum.

Installing the Contact Block
First unlock the operator button. Align the small marking on the edge
of the operator with the small
marking on the yellow bayonet ring.
Hold the contact block, not the bayonet ring. Press the contact block
onto the operator and turn the contact block clockwise until the bayonet
ring clicks.

Notes for installing the contact block
Make sure that the bayonet ring is in the locked position. Check that the
two projections on the bayonet ring are securely in place.
Wiring
Solder Terminal
1. The applicable wire size is 1.25 mm
2
maximum.
2. Solder the terminal at a temperature of 310 to 350°C within 3 sec-
onds using a soldering iron. Sn-Ag-Cu type is recommended when
using lead-free solder. When solder ing, do not touch the enabling
switch with the soldering iron. Also ensure that no tensile force is
applied to the ter minal. Do not bend the terminal or apply excessive
force to the terminal.
3. Use a non-corrosive rosin flux.
4. Because the terminal spacing is narrow, use protective tubes or
heat shrinkable tubes to avoid burning of wire coating or short cir-
cuit.
PC Board Terminal
1. When mounting a contact block on a PC board, provide sufficient
rotating space for the PC board when installing and removing the
contact block.
2. When mounting an XW emergency stop switch on a PC board, make
sure that the operator is securely installed.
3. Do not solder by flow soldering. Otherwise, damage may be caused.
