2. Safety Precautions
・Be sure to read the instruction manual and catalog before installing, wiring, operation, maintenance, or inspection the product.
・Confirm power is off before installation, wiring, maintenance, or inspections. Failure to do so may cause electric shock, fire,
or malfunctions.
・When the product is installed on other equipment, be sure usage is in compliance with all applicable standards and regulations in
the country or region, as required for the system, machine, or facility.
3. Caution in Use
【Before using the product】
・Do not use a power supply that exceeds the rated voltage or current indicated in the specifications. Using a power supply that
exceeds ratings may cause overheating or fire.
・Use wires of appropriate rating. Use of improper wires may cause overheating and fire.
・Follow recommended “Mounting Panel Cutout” dimensions and installation instruction, or switch may be fixed loose and not operate
properly.
・Remove dirt and dust from the switch mounting surface of the panel before installation.
・Do not disassemble the product as it may cause electric shock, fire, or malfunctions.
・Operate the product by hand only. Do not operate using foot, tool, or other objects.
・Chattering and bouncing
Bouncing may occur during a reset operation (pull or turn to reset). Chattering may occur if the switch-mounted equipment is
subjected to shock or vibration. Take appropriate measures to prevent chattering and bouncing on the equipment side.
・Safeguard against excessive shock or vibration, such as dropping. Excessive shock and vibration may result in deformation, damage,
degraded performance, or failure.

【Soldering】
・After inserting the lead wire into the terminal hole, use a soldering iron to ensure a secure connection.
Incomplete soldering may cause overheating in overheating and fire during use.
・Note that if soldering is performed while the terminal is facing up, the flux may enter the interior of the switch. Perform soldering
carefully.
・The solder resistant temperature is 390°C. Complete the soldering within four seconds.
【Usage Environment】
・The product is designed for indoor use.
・Do not install in locations subject to frequent splashing water.
・If the product becomes wet, wipe off with a dry cloth. Using a switch exposed to water may result in water entering inside; if the
water freezes inside the switch, it may not function properly.
・When using the product in environments subject to accumulations of dust and dirt, remove such accumulations from the area around
the switch before use. Accumulated dust and dirt, may affect switch function.
【Routine Care】
・Use a dry cloth to wipe dirt from the actuator. If the actuator is very dirty, wipe with a cloth dampened with a small amount of neutral
detergent, then wipe dry. (Actuator material: Fiber-reinforced PBT)
4. Installing the Switch
(1) Remove the round nut from the switch main body.
(2) With the notch in the O-ring aligned with the anti-rotation tab on the switch main body, insert the switch body into panel. In this
step, align the anti-rotation tab on the switch main body with the anti-rotation keyway on the panel.
(3) Using the fixing nut wrench (AT119), tighten the round nut from the back side of the panel to the recommended tightening torque
of 785 mN·m.
