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.
