Wiring for Screw-Less Clamps
Mounting
W
ires
1. Strip a length of 10 mm off the end of the wire (allowable
range:
10
±
1 mm).
2.
Bunch wire strands together and straighten them.
3. Insert the wire into the insertion hole while pressing the
release button at the side of the hole. (Using a precision
screwdriver
is recommended.)
4.
Let go of the release button to lock the wire into place.
5. After locking, pull on the wire gently to confirm that it is
securely
locked.
Removing W
ires
Remove wires by pulling them while pressing the release button.
Note: When
reusing wires that have
already been locked, cut of
f
the
end of the wire and strip the wire again before using.
Mounting Precautions
1. The
mounting panel thickness must be 0.5 to 3.2 mm.
2.
The mounting ring must be tightened to a torque 0.29 to 0.49 N
⋅m.
3. The
mounting hole must be cut out in the way described previously
. The dimension A is the length required for removing the Switch when
it
is in the mounted state. If Switches are mounted side-by-side separated by less than the specified distance, it may not be possible to
remove
the Switch.
4. Be
sure to mount the Case to the Switch with the correct orientation. Mount with the
•
mark on the Case facing in the same direction as the
side
of the Switch with the direction arrow or the word T
OP.
Case

5. When
using stranded wires with the Screw-Less Clamp, wrap the ends of the wires together first.
6. When
wiring, insert
the wires until they come into contact with something. After wiring, pull on the wires to check that they are secure.
7. After
wiring, ensure that continuous pressure is not applied to the terminals.
8.
Be sure to perform wiring correctly
. Refer to internal connections diagrams and check the terminal numbers before wiring.

Installation
Panel Mounting
After mounting the Pushbutton Unit (i.e., the Pushbutton and the
Case)
to the panel, snap in the Switch Unit (i.e., the Switch and the
Lamp)
from the back of the panel.
Mounting to the Panel
Insert
the Pushbutton Unit into the front of the panel, and fix the lock
ring
and mounting nut from the terminal side.
Make sure that the lock ring is aligned with the thread of the
Case
and the edge of the lock ring is touching the panel.
T
ighten the mounting nuts to a torque of 0.29 to 0.49 N
⋅m.
The maximum tightening torque is 0.49 N

Make sure that the Switch Unit has the correct orientation when
snapping it onto the Case. Align the S mark on the Case with the
groove between the case guards on the NC terminal side of the
Switch
Unit
in the way shown below, and push the Switch Unit into

Removing and Mounting the Pushbutton
1. Remove
the Pushbutton as shown in the following diagram. If
the Pushbutton cannot be removed by hand, use the
A3PJ-5080 Extractor.

Removing from the Switch End
The Lamp can be removed by hand once the Switch is removed
using
the A16Z-5080 Extractor
.
Installing the Lamp
When
mounting the Lamp, make
sure it is facing the direction shown
in the following diagram. Insert the Lamp while matching the pro-
truding
part of the Lamp and the
small guides on the outer surface of
the Case.
Protruding
part
The Lamp can be mounted from the Pushbutton end by using the
A16Z-5080 Extractor. The lamp can be mounted by following the
opposite
procedure for removing the Lamp.

Precautions
WARNING
Do not apply a voltage between the incandescent lamp and
the
terminal that is greater than the rated voltage.
If the incan
-
descent
lamp is broken, the operating part may pop out.
Always turn OFF the power and wait for 10 minutes before
replacing the incandescent lamp. If the lamp is replaced
immediately
after the power is turned OFF
, the remaining heat
may cause burns.
Correct Use
Mounting
Always make sure that the power is turned OFF before mounting,
removing,
or wiring the Switch, or performing maintenance.
Do not tighten the mounting nut more than necessary using tools
such as pointed-nose pliers. Doing so will damage the mounting
nut.
The tightening torque is 0.29 to 0.49 N
⋅m.
Wiring
Solder
terminals and quick-connect terminals
(#1
10) are commonly
used
for terminals.
Be sure to use electrical wires that are a size appropriate for the
applied voltage and carry current (conductor size is 0.5 to 0.75
mm2). Perform soldering according to the conditions provided
below.
If the soldering is not properly performed, the lead wires will
become
detached, resulting in short-circuits.
1. Hand soldering: 30 W
, within 5 s
2. Dip soldering: 240
°
C, within 3 s
Wait for one minute after soldering before exerting any external
force
on the solder
.
Use non-corrosive resin fluid as the flux.
Make
sure that the electric cord is wired so that it does not touch the
Unit.
If the electric cord touches the Unit,
then electric wires with a
heat
resistance of 100
°
C min. must be used.
After wiring the Switch, maintain an appropriate clearance and
creepage
distance.
Operating Environment
The
IP65 model is designed with a protective
structure so that it will
not
sustain damage if it is subjected to water from any direction
to
the front of the panel.
Using the Microload
Insert
a contact protection
circuit, if necessary
, to prevent the reduc

tion
of life
expectancy due to extreme wear on the contacts caused
by loads where inrush current occurs when the contact is opened
and
closed.
The
A16 allows both a standard load (125 V at 5A, 250
V at 3 A) and
a microload. If a standard load is applied, however, the microload
area
cannot be used. If the
microload area is used with a standard
load, the contact surface will become rough, and the opening and
closing
of the contact for a microload may become unreliable.
The minimum applicable load is the N-level reference value. This
value indicates the malfunction reference level for the reliability
level
of 60% (
λ
60) (conforming to JIS C5003).
The equation, λ 60 = 0.5 x 10–4/time indicates that the estimated
malfunction rate is less than 1/2,000,000 with a reliability level of
60%.

If the panel is to be finished with coating, etc., make sure that the
panel
meets the specified dimensions after the coating.
Do not subject the Switch to extreme shock or vibration. Doing so
will cause malfunctions and damage to the Switch.
Do
not let sharp objects come into contact
with the Switches that are
made of resin. Doing so will damage the Switches, causing
scratches
on the outside of the operating parts, and malfunction.
When handling the Switches, do not throw or drop them.
Do not allow the Switch
to drop and hit the
ground.
Do not place or drop
heavy objects on the
Switch.
Do not operate the Switch
with hard or sharp objects.
