Precautions for Safe Use

• Be sure to ground. Otherwise electric shock may result.

• Do not touch charged switch terminals while the switch is carrying current, otherwise electric shock may result.

• Do not disassemble or touch the inside while the power is turned on, otherwise electric shock may result.

• Do not handle products without proper protective gears; doing so may result in injury.

• Connect a fuse which has 1.5 to 2 times higher breaking current than the product, in order to prevent products from

short-circuit damage.

• On the occasion when using the switch with EN/IEC/GB ratings, use a 10 A fuse that complies IEC60269, either type

gG or gL.

• Operating conditions will affect product durability. Be sure to check with actual using conditions before usage.

• Do not drop the switch.

• Do not connect a Single Limit Switch to two power supplies that are different in polarity or type. This may increase

the risk of interference.

• Be sure to keep the load current less than the rated value. Otherwise, there is the possibility that the switch may be

damaged and/or burnout.

• Do not use the Switch by itself in atmospheres containing flammable or explosive gases. Arcs and heat resulted from

constant actuating may cause fire or explosion.

• Be sure to prevent foreign materials such as scrapped cable intrusion into the switch when wiring. Otherwise, there

is the possibility of spoiling normal operations.

• Do not wire to the wrong terminals.

• Using the Switch in a pressed-in state for an extended period of time can accelerate part deterioration and also lead

to failure to return to the original position. Check the Switch beforehand, and perform periodic inspection and

replacement.

• Do not store or use the switch at the following places: (i)where the temperature fluctuates greatly. (ii)where the

humidity is very high and condensation may occur. (iii)Where the vibration is great. (iv)Where there is direct sun light.

(v)Where exposed to salty winds. (vi)Where exposed to cutting powder, machining chips, oil, and chemicals inside the

protective doors. (vii)Where exposed to cleansers, thinners, and other solvents.

• Do not use or store the Switch in locations with corrosive gas, such as sulfuric gas (H2S or SO2), ammonium gas

(NH3), nitric gas (HNO3), or chlorine gas (Cl2), or high temperature and humidity. Otherwise, contact failure or

corrosion damage may result.

• Do not disassemble and/or modify the switch at any time. Otherwise, there is the possibility of spoiling the normal

operation.

• Do not apply deformative and/or degenerative forces to products.

• If products have been used over an extended period of time or uses stated in products datasheets, contact reliability

may still degrade due to natural oxidation; resulting in inadequate conductivity, which may lead to an accident. Please

swiftly preform inspections and insure proper replacements are carried out.

• Only allow certified professionals to preform installing and maintenance tasks.
