Safety Precautions
• Turn off the power to A series before starting installation, removal,
wiring, maintenance, and inspection of the units. Failure to turn power
off may cause electrical shocks or re 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 re hazard.
Operating Instructions
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 below.

Note: Make sure that the spring is inserted in the correct direction. The
base of spring must t 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 the same marking plate as
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 units into a panel, use the optional locking ring
wrench (MT-002/-003/-004) to tighten the locking ring. Do not use
pliers. Tightening torque must not exceed 0.78 N·m (A8, A1 series :
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 is recommended when using lead-free solder. When
soldering, do not touch the 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 unit with the TOP markings on the 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.
