Safety Precautions
Refer to the “Precautions for All Switches” and “Precautions for All Safety Door Switches”.
Installation Environment
Wiring
Electric shock may occasionally occur.
Do not use metal connectors or metal conduits.
• Do not use the Switch submersed in oil or water or in locations
• Do not switch circuits for two or more standard loads (250 VAC,
• Always attach the cover after completing wiring and before using
Injury may occasionally occur. Always check to make
sure that the safety functions operate correctly before
using the machine. The safety functions may not operate
correctly because of wiring mistakes, setting mistakes,
or Switch malfunction, causing some machines to
continue operating in situations where they should be
stopped.
Injury may occasionally occur. If the machine is used
with the release key in the UNLOCK position, the
electromagnetic lock may not operate, causing some
machines to continue operating in situations where they
should be stopped. Be sure to put the release key in the
LOCK position before using the machine. Also, check
the condition of the lock and safety circuits.
Injury may occasionally occur. Always ensure that the
release key is set to "UNLOCK" or that the Operation
Key is inserted before changing the direction of the head.
Not doing so may damage the Switch, causing some
machines to continue operating in situations where they
should be stopped. Refer to “Release Key” on page 15.
Injury may occasionally occur. When the
electromagnetic lock function or Switch function is
damaged, some machines may continue operating in
situations where they should be stopped. Do not use the
electromagnetic lock function of the Switch in place of a
door lock. Always provide a lock separate from the
Switch, attach a warning seal to prevent people from
using excessive force to open the door when it is locked,
or provide an indicator lamp to show the locked/unlocked
status of the door.
continuously subject to splashes of oil or water. Doing so may
result in oil or water entering the Switch. (The IP67 degree of
protection of the Switch specifies the amount of water penetration
after the Switch is submerged in water for a certain period of time.)

the Switch. Do not supply power when the cover is not attached.
Electric shock may occur if the Switch is used without the cover
attached.
Precautions for Safe Use
!CAUTION
DANGER
Installation
The Switch contacts can be used with either standard loads or
microloads. Once the contacts have been used to switch a load,
however, they cannot be used to switch smaller loads. The contact
surfaces will become rough once they have been used and contact
reliability for smaller loads may be reduced.
Release Key
Hinged Door
If an attempt is made to open the door beyond the lock position when
the Switch is used for a hinged door at a location near to the hinged
side, where the Operation Key’s insertion radius is comparatively
small, the force imposed will be much larger than for locations far from
the hinged side, and the lock may be damaged. Mount the Switch
close to the handle.
• Make sure the Switch is mounted securely to prevent it from falling
• Do not use the Switch as a stopper.
• Do not subject the Switch to a shock that exceeds the Switch's
• The release key is used to unlock the Switch in case of emergency
• If the release key setting is changed from LOCK to UNLOCK, the
• The release key is set in the unlock position at the factory for the
• Do not use the release key to start or stop machines.
• The auxiliary lock must only be released by authorized personnel.
• Do not impose a force exceeding 1 N·m on the release key screws.
• To prevent the release key from being used by unauthorized
off. Otherwise injury may result.
Be sure to install a stopper as shown in the following illustration to
ensure that the base of the Operation Key does not strike the
Head, and adjust the stopper to be within the setting zone (0.5 to 3
mm) of the base of the Operation Key.
