Safety Precautions
• 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 re 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 re 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 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 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.

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 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
IP65 (IEC 60529) switch guards must be used with IP65 (IEC 60529)
control units only. Even if IP65 type switch guards are installed,
enclosed type (IP40) control units are not made waterproof.
