Precautions for Safe Use • Never perform wiring work on a Switch while power is being supplied. Never touch terminals and other charged parts while power is being supplied. Doing so may result in electrical shock. • Never attempt to disassemble or modify the Switch in any way. Doing so may prevent correct operation. • Switch functionality may be inhibited. Do not drop the Switch. Never apply a force that would deform or alter the nature of the Switch. • The durability of the Switch is greatly affected by operating conditions. Evaluate the Switch under actual working conditions before permanent installation and use the Switch within a number of switching operations that will not adversely affect the Switch’s performance. • Do not use a load voltage or current that exceeds the rating. Doing so may damage or cause burning in the Switch. • Do not use the Switch in a location with inflammable or explosive gases, or where the Switch would be subjected to inflammable solvents. The arcs and heat generated when the Switch is operated can cause ignition or explosions. • Do not use the Switch where sulfur gas (H2S, SO2), ammonia gas (NH3), nitric acid gas (HNO3), chlorine gas (Cl2), or other harmful gases are present or where high humidity is present. Contact faults and damage due to corrosion may interfere with the functionality of the Switch. • Do not use the Switch in oil or water or in an environment subject to constant contact with oil or water. The oil or water may enter the Switch, causing failure. • Do not use or store the Switch in the following locations. •Locations subject to rapid temperature changes •Locations subject to condensation due to high humidity •Locations subject to vibration •Locations subject to direct sunlight •Locations subject to salty air • Make sure that the rubber washer is in place between the Operation Unit and the panel. Otherwise, the specifications of the protective structure may not be satisfied. • Do not subject the Contact Block or wiring to excessive force. The Contact Block may be damaged or deformed and faulty contact may occur. Precautions for Correct Use Mounting • Do not tighten the Mounting Nut more than necessary using tools such as pointed-nose pliers. Doing so will damage the Mounting Nut. (The tightening torque of the Mounting Nut is 1.0 to 2.0 N·m.) Wiring • Terminal screws must be M3.5 Phillips or slotted screws with a square washer. • The terminal screw tightening torque is 1.0 to 1.3 N·m. • Solid wires, stranded wires, and crimp terminals can be connected to the Switch. Stranded wires: AWG14 to AWG16 Solid wire: 1.6 dia. max. Bare Crimp Terminals 7.2 mm max. 16.0 mm max. 7.2 mm max. 16.0 mm max. Crimp Terminals with Insulating Sheathes 7.2 mm max. 20.2 mm max. 7.2 mm max. 20.2 mm max. • After wiring the Switch, maintain appropriate clearance and creepage distances. Operating Environment • The Switch is intended for indoor use only. Using the Switch outdoors will result in failure. LED Lamps • A current-limiting resistor is built into the LED Lamp, so external resistance is not required. • False Lighting of the LED Lamp The LED Lamp will light with a microcurrent of approx. 0.1 mA or less. Take countermeasures, such as adding a resistor in parallel to the LED Lamp, to prevent false lighting. The micro-current varies with the machine (due to leakage current, stray capacity between cables, etc.). Select a resistance value and allowable power consumption according to the actual current.
