Operating instructions for emergency stop switch ES-XW/XN
Projection
SAFETY NOTE
Read this instruction sheet and the catalog for
the ES-XN/XW series emergency stop switches
to make sure of correct operation before starting
installation, wiring, operation, maintenance, and
inspection. Make sure that the instruction sheet
is kept by the end user.
Turn off the power to the ES-XN/XW before
starting installation, wiring, maintenance and
inspection of the ES-XN/XW. Failure to turn power
off may cause electric shock or fire hazard.
Use wires of a proper size to meet voltage and
current requirements. Tighten the M3 terminal
screws to a tightening torque of 0.6 to 0.8 Nm.
Improper wires and loose terminals during operation will cause overheating and fire hazard. Provide
a proper protection against electric shocks.
Removing/Installing Contact Block and
Panel Mounting
Removing
First unlock the operator button. Squeeze the latch
lever on the yellow bayonet ring and pull back the
bayonet ring with force until the latch pin clicks,
then turn the contact block counter-clockwise and
pull out.

(Squeeze)
(Pull)
Notes for removing the contact block
1) With the button in the locked position, do not
remove the contact block, otherwise the switch
may be damaged.
2) When the contact block is removed, the monitor
contact (NO contact) is closed.
3) While removing the contact block, do not exert
an excessive force, otherwise the switch may be
damaged.
4) An LED lamp is built into the contact block for
illuminated pushbuttons. When removing the
contact block, pull out the contact block straight
to prevent damage to the LED lamp. If an excessive
force is exerted, the LED lamp may be damaged
and fail to light.
Panel Mounting
Remove the locking ring from the operator and
check that the rubber gasket is in place. Align
the anti-rotation projection on the bezel with the
recess in the panel, insert the operator from panel
front into the panel hole and tighten the locking
ring using ring wrench ES-XN9Z-T1 to a torque
of 2.5Nm. Face the side without thread on the
operator with TOPmarking upward, and tighten
the locking ring using ring wrench ES-MW9Z-T1
to a torque of 2.0Nm.

Before installing the emergency stop nameplate,
break the projection on the nameplate using pliers.
Installing
First unlock the operator button. Align the small
▼ marking on the edge of the operator sleeve
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
1) With the button in the locked position, do not
install the contact block, otherwise the switch
may be damaged.
2) Make sure that the bayonet ring is secured in the
locked position.

Notes for Operation
When using the emergency stop switch for safetyrelated equipment in a control system, refer to the
safety satandards and regulations in each country
and region depending on the application purpose of
the actual machines and installations to make sure
of correct operation. Before using the emergency
stop switch, perform risk assessment to make
sure of safety.
Wiring
Tighten the terminal screws to a torque of 0.6 to 0.8 Nm.
Contact Bouncing
When the button is reset by pulling or turning, the NC
main contacts cause bouncing. When pressing the
button, the NO monitor contacts cause bouncing.
When designing a control circuit, take the bouncing
into consideration (reference value: 20 ms).
LED Illuminated Switches
The LED lamp is built into the contact block and
cannot be replaced.
Handling
Do not expose the switch to excessive shocks and
vibrations, otherwise the switch may be deformed
or damaged, causing malfunction or operation
failure.
Padlock Emergency Stop (ES-XN)
The padlockable emergency stop switches can
be reset by turning only, and cannot be pulled to
reset. Do not attempt to pull to reset, otherwise
damage or malfunction may result.

To prevent the ES-XW emergency stop switch from
rotating when resetting from the latched position with
excessive force, use of a nameplate (ES-HWAV-27) is
recommended. Align the side without thread on the
operator with TOP marking, the small ▲ marking
on the projection on the nameplate, and the recess
on the mounting panel.
