Applicable panel thickness
The applicable panel thickness is 1 to 6mm.
However, a ø30
switch mounted with their adapters should have an applicable
panel thickness of 1 to 4.5mm.
If a legend plate is used, the panel should be made thinner
by subtracting the thickness of that component.
Note: If a legend plate or s
imilar is
used between the switch and
the fitting surface of the panel, the thickness of the legend panel should be
1.6mm or less. If the thickness exceeds the value of 1.6mm, it may prevent
the fixing function of the switch.

• Caution at the removing process of the contact unit from the operator
(1) When the contact unit is removed from the operator, at the process, “NO”
contact of the unit is turned into “ON” position.
(2) At the process when the contact unit is removed from the operator, don’t
give excessive force to the unit. It may cause the switch to break or to go
into maloperation.
●
Mounting the operator on the panel
Remove the tightening nut and washer from the packaged
state of the operator, checking the packing whether it is
placed properly on to the fitting surface of the front side
of
the panel, insert the operat
or while
keepin
g the
mark
at
the top position into the installation hole of the panel.
The
operator penetrates the panel through the installation
hole
to the rear side of the panel. It is fixed at the rear
side of
the panel with the tightening nut turned by the
tightening
wrench.
Note 1 : The proper tightening torque is 1.0 to 1.5N·m for AR22, and 1.5 to 2.5N·m
for AR30.
Note 2 : The tightening nut has two faces, convex and concave. Face the concave
side of it to the panel when it tightens up the operator at the rear side of
the panel. If it is used in the opposite face, the operator will not be fixed
properly there.
Note 3 : Check the tightening nut regularly whether it tightens the operator
properly. If it seems that tightening is not sufficient, do not forget to
tighten the screw increasingly.
Note 4 : Do not use pliers or other improper tools to tighten the nut, and do not
tighten it excessively, or the nut may be damaged or the switch may
malfunction.
●
Mounting the contact unit
Meet the mark on the contact unit to the same mark
on the operator, insert the contact unit completely into
the
operator until it makes a click sound. (The click sound
indicates
the contact unit is completely connected to the
operator.)
After the contact unit is set, check the sequence
and
test
the unit
.
●
Caution when the contact unit is set in
(1)
This release cover must be twisted in order to remove or
connect the contact unit to the operator portion. Please
note: The position of the release cover will be in a
different position (either twisted to the right or left) from
when it is connected to the operator.
(2)
The triangle marks on the grooves of the operator and
contact unit will need to match up when connecting the
two parts. Please note: Not connecting the correct
grooves with the correct marks can cause it to break.

not operate correctly.
Don't give excess force to the button as it will damage the
circuit.
