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 .

Panel Mounting
Remove the locking ring from the operator and check that
the rubber gasket is in place. 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.
• • • • Notes for Panel Mounting
To prevent the XW emergency stop switch from rotating
when resetting from the latched position, use of an anti-rota-
tion ring (HW9Z-RL) or a nameplate is recommended.
Installing the Contact Block
First unlock the operator button. Align the small
on the edge of the operator with the small
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.

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.
