Safety Precautions
Operating Instructions
• Turn off the power to A series control units before starting
installation, removal, wiring, maintenance, and inspection of the
control units. Failure to turn power off ma y cause electrical shocks
or fire hazard.
• To avoid a burn on your hand, use the lamp holder tool when
replacing lamps.
• For wiring, use wires of a proper size to meet the voltage and
current requirements. Failure to tighten terminal screws may
cause overheating and create a fire hazard.
Replacement of Lens and Marking Plate
•Removal
Remove the lens assembly (color lens, marking plate, lens holder,
and spring) by holding the color lens recesses with the Lens
Remov al Tool (MT-101) and pulling it out. Remove the marking plate
by disengaging the latches between the color lens and lens holder.
The marking plate must be
engraved on the front side
as shown at right.
When using a color film,
insert it between the color
lens and marking plate.
•Installation
Place the marking plate on
the lens holder in the correct direction, and press the color lens onto
the lens holder to engage the latches.
Put the spring on the lens holder and insert the lens holder into the
housing in the correct direction.
Marking
For A series illuminated pushbuttons, legends and symbols can be
engraved on the built-in marking plates, or printed film can be
inserted under the lens for labelling purposes.

Use the lamp holder tool (OR-77) to remove lamps. Do not use
pliers.
•Installation
Use the lamp holder tool (OR-77) to install lamps. Note the correct
side of the tool for removal or installation.
Panel Mounting
When mounting the control units into a panel, use the optional
locking ring wrench (MT-001) to tighten the locking ring. Do not use
pliers. Tightening torque must not exceed 0.88 N·m. Excessive
tightening will damage the locking ring.
Wiring
Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. Sn-Ag-Cu type is recommended when using lead-
free solder. When soldering, do not touch the control unit with the
soldering iron. Also ensure that no tensile force is applied to the
terminal. Do not bend the terminal or apply excessive force to the
terminal. Use a non-corrosive rosin flux.
Installing the Socket
Install the socket on the control unit with the TOP markings on the
control unit and the socket placed in the same direction.
Switch Guard
Waterproof (IP65) / oiltight type switch guards must be used with
waterproof (IP65) / oiltight type control units only. Even if IP65 type
switch guards are installed, enclosed type (IP40) control units are
not made waterproof.
Operating Voltage of LED Lamps
The operating voltage of 5V DC is measured at complete DC.
Other Notes
•Close Proximity Mounting
When mounting pilot lights or illuminated pushbuttons collectiv ely or
lighting them continuously, heat may cause the ambient
temperature to rise above the rated operating temperature. When
the mounting panel is not made of metal or when the control units
are mounted in an enclosed panel, provide for ventilation or lower
the operating voltage.
•Replacement of Buttons (Illuminated/Non-illuminated)
Do not replace buttons of maintained action units while the b utton is
in the locked position. Replacing the button in the locked position
may damage the internal mechanism. Be sure to release the button
before replacing.
•Operating and Storage Environment
1. Make sure that the operating/storage temperature and humidity
are within the ratings.
2. Do not use enclosed type units in an environment subject to oil,
water or dust accumulation. In such an area, use the waterproof/
oiltight units (IP65).
•Microswitch Contacts
Do not connect NO and NC contacts of a microswitch to different
voltages or different power sources to prevent a dead short-circuit.
•IP65 Type Units
IP65 type units are evaluated by conventional cutting and cooling
oils, and can not be used with some special oils. Contact IDEC for
resistance against specific oils.

Safety Precautions
Operating Instructions
• Turn off the power to A series control units before starting
installation, removal, wiring, maintenance, and inspection of the
control units. Failure to turn power off may cause electrical shocks
or fire hazard.
• To avoid burning your hand, use the lamp holder tool when
replacing lamps.
• For wiring, use wires of a proper gauge to meet the voltage and
current requirements. Failure to tighten terminal screws may
cause overheating and create a fire hazard.
Replacement of Lens and Marking Plate
•Removal
Remove the lens assembly (color lens, marking plate, lens holder,
and spring) by holding the color lens recesses with the Lens
Remov al Tool (MT-101) and pulling it out. Remove the marking plate
by disengaging the latches between the color lens and lens holder.
The marking plate must be engraved on the front side as shown
below.
•Installation
Place the marking plate on the lens holder in the correct direction,
and press the color lens onto the lens holder to engage the latches.
Put the spring on the lens holder and insert the lens holder into the
housing in the correct direction.
•Installing Non-illuminated Button
Non-illuminated pushbuttons contain a marking plate like
illuminated units. Be sure to install the marking plate when replacing
the button.
Replacing the LED Lamp
•Removal
Use the lamp holder tool (OR-66) to remove lamps. Do not use
pliers.
•Installation
Use the lamp holder tool (OR-66) to install lamps. Note the correct
side of the tool for removal or installation.
Panel Mounting
When mounting the control units onto a panel, use the optional
locking ring wrench (MT-002) to tighten the locking ring. Do not use
pliers. Tightening torque must not exceed 0.78 N·m. Excessive
tightening will damage the locking ring.
Wiring
Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. Sn-Ag-Cu type is recommended when using lead-
free solder. When soldering, do not touch the control unit with the
soldering iron. Also ensure that no tensile force is applied to the
terminal. Do not bend the terminal or apply excessive force to the
terminal.
Use non-corrosive rosin flux.
Installing the Socket
Install the socket on the control unit with the TOP markings on the
control unit and the socket placed in the same direction.
Operating Voltage of LED Lamps
The operating voltage is measured at complete DC. When using a
pulsating voltage such as a full-wave rectification voltage, keep
peak currents within the forward current If. Peak currents exceeding
the If may shorten the LED lamp life.
Other Notes
•Close Proximity Mounting
When mounting pilot lights or illuminated pushbuttons collectiv ely or
lighting them continuously, heat may cause the ambient
temperature to rise above the rated operating temperature. When
the mounting panel is not made of metal or when the control units
are mounted in an enclosed panel, provide for ventilation or lower
the operating voltage.
•Replacement of Buttons (Illuminated/Non-illuminated)
Do not replace buttons of maintained action units while the b utton is
in the locked position. Replacing the button in the locked position
may damage the internal mechanism. Be sure to release the button
before replacing.
•Operating and Storage Environment
1. Make sure that the operating/storage temperature and humidity
are within the ratings.
2. Do not use enclosed type units (IP40) in an environment subject
to oil, water or dust accumulation. In such an area, use the
waterproof/oiltight units (IP65).
•Microswitch Contacts
Do not connect NO and NC contacts of the microswitch to different
voltages or different power sources to prevent a dead short-circuit.
•IP65 Type Units
IP65 type units are evaluated by conventional cutting and cooling
oils, and can not be used with some special oils. Contact IDEC for
resistance against special oils.

LED Lamp Ratings (LAD-S Type)
Note: When LED lamps are used on voltages other than the above, external resistor value R is determined by the following formula:
R = (operating voltage – Vf) / If
• LED lamps do not have a current-limiting resistor, and external resistors of recommended values for each voltage
must be provided. Connect a current-limiting resistor in series, otherwise LED lamps will be damaged. Because
no protection diode is contained, ensure the correct polarity is observed.

Safety Precautions
Operating Instructions
• Turn off the power to A series control units before starting
installation, removal, wiring, maintenance, and inspection of the
control units. Failure to turn power off may cause electrical shocks
or fire hazard.
• To avoid burning your hand, use the lamp holder tool when
replacing lamps.
• For wiring, use wires of a proper size to meet the voltage and
current requirements. Failure to tighten terminal screws may
cause overheating and create a fire hazard.
Replacement of Lens and Marking Plate
•Removal
Remove the operator (color lens, marking plate, lens holder, and
spring) by holding the color lens recesses with the Lens Removal
Tool (MT-101) and pulling it out. Remove the marking plate by
disengaging the latches between the color lens and lens holder.
The marking plate must be engraved on the front side as shown
below.
•Note: Make sure that the spring is inserted in the correct
direction. The base of spring must fit the groove in the
holder.
Installation
Place the marking plate on the lens holder in the correct direction,
and press the color lens onto the lens holder to engage the latches.
Put the spring on the lens holder and insert the lens holder into the
housing in the correct direction.
•Installing Non-illuminated Button
Non-illuminated pushbuttons contain a marking plate like illumi-
nated units. Be sure to install the marking plate when replacing the
button.
Replacing the LED Lamp
•Removal
Use the lamp holder tool (OR-66) to remove lamps. Do not use
pliers.
•Installation
Use the lamp holder tool (OR-66) to install lamps. Note the correct
side of the tool for removal or installation.
Panel Mounting
When mounting the control units onto a panel, use the optional
locking ring wrench (MT-004) to tighten the locking ring. Do not use
pliers. Tightening torque must not exceed 0.29 N·m. Excessive
tightening will damage the locking ring.
Wiring
Solder the terminal at 350°C within 3 seconds using a 60W
soldering iron. Sn-Ag-Cu type is recommended when using lead-
free solder. When soldering, do not touch the enabling switch with
the soldering iron. Also ensure that no tensile force is applied to the
terminal. Do not bend the terminal or apply excessive force to the
terminal.
Use a non-corrosive rosin flux.
Installing the Socket
Install the socket on the control unit with the TOP markings on the
control unit and the socket placed in the same direction.
Operating Voltage of LED Lamps
The operating v oltage of 5V DC is measured at complete DC. When
using a pulsating voltage such as a full-wave rectification voltage,
keep peak currents within the forward current If. Peak currents
exceeding the If may shorten the LED lamp life.
Other Notes
•Close Proximity Mounting
When mounting pilot lights or illuminated pushbuttons collectiv ely or
lighting them continuously, heat may cause the ambient
temperature to rise above the rated operating temperature. When
the mounting panel is not made of metal or when the control units
are mounted in an enclosed panel, provide for ventilation or lower
the operating voltage.
•Replacement of Buttons (Illuminated/Non-illuminated)
Do not replace buttons of maintained action units while the b utton is
in the locked position. Replacing the button in the locked position
may damage the internal mechanism. Be sure to release the button
before replacing.
•Operating and Storage Environment
1. Make sure that the operating/storage temperature and humidity
are within the ratings.
2. Do not use enclosed type units in an environment subject to oil,
water or dust accumulation.
•Microswitch Contacts
Do not connect NO and NC contacts of the microswitch to different
voltages or different power sources to prevent a dead short-circuit.
