Mounting
Installation
Do not use the Switch as a stopper.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 (1 to 3mm) of the base of the Operation Key.
Do not subject the Switch to a shock that exceeds the Switch's shock resistance of 1,000 m/s 2 .
Securing the Door
When the door is closed (with the Operation Key inserted), the Operation Key may exceed the set zone
because of, for example, the door's own weight, machine vibration, or the door cushion rubber. Also, it may
not be possible to pull out the Operation Key if there is weight placed on the Operation Key. Secure the door
with a stopper so that the Switch is not included as the locking member of the door.
Set zone:MA2 series operation manual
Appropriate Tightening Torque
• When loosening a screw with an electrical screwdriver or similar tool while pressing down on the screw
head, do not continue turning the screw past the point where the threads disengage.Doing so may strip
the end of the threads.
Switch and Operation Key Mounting
• Use M4 screws and washers to mount the Switch and Operation Key, and tighten the screws to a suitable
torque.To ensure safety, use screws that cannot be easily removed or another means to prevent the Switch and
Operation Key from easily being removed.
• Do not impose excessive force on the Operation Key while the Key is inserted into the Switch or drop the
Switch with the Operation Key inserted. Doing either of these may deform the Key or break the Switch.

Wiring
• Do not wire the Switch while power is being supplied. Doing so may result in electric shock.
• Do not let particles, such as small pieces of lead wire, enter the switch body when wiring.
• When connecting to the terminals via insulating tube and M3.5 crimp terminals, cross the crimp terminals
as shown above so that they do not rise up onto the case or the cover.
• Applicable lead wire size: AWG20 to AWG18 (0.5 to 0.75 mm 2 ).Use lead wires of an appropriate length.
Not doing so may result in excess length causing the cover to rise and not fit properly.
• Do not push crimp terminals into gaps in the case interior. Doing so may cause damage or deformation of
the case.
• Use terminals having the thickness of 0.5 mm or less to avoid the contact between the terminal and the
interior of the Switch case.

Operation Key
• Use only the designated Operation Key. The Head has been designed so that operation is not possible
with a screwdriver or other tools. Using anything other than the designated Operation Key may damage the
Switch or affect machine safety.
• Do not operate the Switch with anything other than the special NEWMAZZ Operation Key, otherwise the
Switch may break or the safety of the system may not be maintained.
• Do not impose excessive force on the Operation Key while the Key is inserted into the Switch or drop the
Switch with the Operation Key inserted. Doing either of these may deform the Key or break the Switch..MA2 series operation manual
Head Direction
• Remove the four screws of the head to enable changing the mounting direction of the head. The head can be
mounted in four directions. Ensure that no foreign material enters the interior of the Switch.
• Do not change the head direction with the cover removed.
• Do not insert or remove the Operation Key with the Switch head removed. Doing so may make it impossible
to insert the Operation Key.
Solenoid
• The solenoid will heat when it carries current. Do not touch it.
• DC solenoid has polarity. Confirm terminal polarity before wiring it.
Release Key
• The release key is used to unlock the Switch in case of emergency or if the power supply to the Switch
stops.
• If the release key setting is changed from LOCK to UNLOCK, the lock will be released and the safety door
can be opened(mechanical lock models only).
• When a Switch with a solenoid lock is in a locked state (i.e., when the solenoid is ON), do not change the
release key from the LOCK to the UNLOCK position. Internal parts may be damaged.
• The release key is set in the unlock position at the factory for the MA2-FAS, Key insertion,You need to
energize the solenoid or rotate the unlocking knob to the unlocking position to pull out the key.
• 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 0.5 N·m on the release key screws.The release key may be damaged and
may not operate properly.
•To prevent the release key from being used by unauthorized personnel, set it to LOCK and seal it with
sealing wax.
Attaching a Cover
• When attaching a cover, be sure that the seal rubber is in place and that there is no foreign material present.
If the cover is attached with the seal rubber out of place or if foreign material is stuck to the rubber, a proper
seal will not be obtained.
• Do not use any screws to connect the cover other than the specified ones. The seal characteristics may be
reduced.
Solenoid lock
The door is locked only when the solenoid is turned ON. This means that the door will be unlocked if there
is a power interruption and so this model cannot be used in systems that would maintain a hazardous state
(e.g., systems requiring toxic gases,high temperatures, or gears that would continue to turn due to inertia).
Processing the Conduit Outlet
•Use a cable gland with the length of the screw not exceeding 9 mm to avoid interference with the inside of
the Switch case..
•Attach a conduit cap to the unused conduit outlet when wiring and tighten it to a suitable torque. The conduit
cap is provided with the Switch.MA2 series operation manual
