WARNING Do not apply a voltage between the incandescent lamp and the terminal that is greater than the rated voltage. If the incandescent lamp is broken, the Operation Units may pop out. Always turn OFF the power and wait for 10 minutes before replacing the incandescent lamp. If the lamp is replaced immediately after the power is turned OFF, the remaining heat may cause burns. Precautions for Correct Use Mounting • Do not perform wiring with power supplied to the Switch. Do not touch the terminals or other charged parts of the Switch while power is being supplied. Doing so may result in electric shock. • Always make sure that the power is turned OFF before mounting, removing, or wiring the Switch, or performing maintenance. Do not tighten the mounting ring more than necessary using tools such as pointed-nose pliers. Doing so will damage the mounting ring. The tightening torque is 0.98 to 1.96 N·m. • Recommended panel thickness: 1 to 5 mm. • When mounting the caps after changing the LED or the caps, tighten the caps at a tightening torque of 0.49 tp 0.78 N·m. LED • The LED current-limiting resistor is built-in, so internal resistance is not required. • If commercially available LEDs are used, select the ones that meet the following conditions: Base: BA9S/13 Overall length: 26 mm max. Power consumption: 2.6 W max. When DC-specific LEDs are used, wire the Switch so that the X1 terminal is positive. • Mis-lighting of the LED The LED lights with approx. 0.1 mA or less of micro-current. Take a countermeasure like adding a resistor to prevent mis-lighting in parallel to the LED. The micro-current varies with the machine (leak current or stray capacity between cables, etc.). Select resistance value and allowable power consumption that meet the actual current. (Circuit example) In case of using 24 VAC/VDC, Direct lighting X1 LED lamp R:10kΩ (1W) Bleeder resistor X2 Wiring • Terminal screws must be Phillips or slotted M3.5 screws with a square washer. • The tightening torque is 1.08 to 1.27 N·m. • Solid wires, stranded wires, and crimp terminals can be connected to the Switch.
