2. Safety Precautions
・Be sure to read the instruction manual and catalog before installation, wiring, operation, maintenance, or inspection of the product.
・Confirm that the 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 that the usage is in compliance with all applicable standards and
regulations in the country or region as required for the system, machine, or facility.
3. Cautions 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 the ratings may cause overheating or fire.
・Use wires of the appropriate rating. Use of improper wires may cause overheating and fire.
・Follow the recommended Mounting Panel Cutout dimensions and installation instructions or the switch may come loose and not
operate properly.
・Remove dirt and dust from the switch mounting surface of the panel before installation.
・Do not disassemble the product because doing so may cause electric shock, fire, or malfunctions.
・Operate the product by hand only. Do not operate using the feet, tools, or other objects.
・Chattering and bouncing
Bouncing may occur during the reset operation (pull or turn to reset). Chattering may occur if the switch-mounted equipment is
subjected to shock or vibration. Take the appropriate precautions to prevent chattering and bouncing of the equipment.
・Safeguard against excessive shock or vibration, such as dropping. Excessive shock and vibration may result in deformation, damage,
degraded performance, or failure.

FF01/Rev.01/EN
【Soldering】
・After inserting the lead wire into the terminal hole, use a soldering iron to ensure a secure connection.
Incomplete soldering may cause overheating and fire during use.
・Note that if soldering is performed while the terminal is facing up, 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 the product in locations subject to frequent splashing of water.
・If the product becomes wet, wipe off with a dry cloth. Using a switch exposed to water may result in water entering the inside; if the
water inside freezes, the switch 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 the 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 nut wrench (AT119), tighten the round nut from the back of the panel to the recommended tightening torque of 785
mN·m.
