Warning Indications

Meaning of Product Safety Symbols

 

!

CAUTION

Doing so may occasionally result in minor injury due 
to electric shock. Do not touch the Relay while the 
power supply is ON, except for the adjustment knob.

There is a risk of minor electrical shock, fire, or device 
failure. Do not allow any pieces of metal, conductors, or 
cutting chips that occur during the installation process to 
enter the product.

Explosions may cause minor injuries. Do not use the 
product in locations with inflammable or explosive 
gases.

There is a risk of minor electrical shock, fire, or device 
failure. Do not disassemble, modify, repair, or touch 
the inside of the product.

Use of the product beyond its life may result in 
contact welding or burning. Make sure to consider the 
actual operating conditions and use the product 
within its rated load and electrical life count. The life 
of the output relay varies significantly with the switching 
capacity and switching conditions.

If the Relay is used with incorrect wiring, fire may 
occasionally occur, possibly resulting in physical 
damage. Check the wiring for mistakes before you 
turn ON the power supply.

If the Relay fails, monitoring and alarm outputs may 
fail to operate. This may result in physical damage to 
the facilities, equipment, or other devices that are 
connected to it. To reduce this risk, inspect the Relay 
regularly. To maintain safety in the event of 
malfunction of the Relay, take appropriate safety 
measures, such as installing a monitoring device on a 
separate line.

If the wire insertion length is insufficient, fire may 
occasionally occur, possibly resulting in physical 
damage. Insert the wires all the way to the back.

The terminal block may be damaged if you insert a 
flat-blade screwdriver in the release hole with 
excessive force. Insert the flat-blade screwdriver into 
the release holes with a force of 15 N or less.

 CAUTION

Indicates a potentially hazardous 

situation which, if not avoided, may result 

in minor or moderate injury or in property 

damage.

Precautions for 

Safe Use

Supplementary comments on what to do 

or avoid doing, to use the product safely.

Precautions for 

Correct Use

Supplementary comments on what to do 

or avoid doing, to prevent failure to 

operate, malfunction, or undesirable 

effects on product performance.

Used to warn of the risk of electric shock under 

specific conditions.

Used for general prohibitions for which there is 

no specific symbol.

Used to indicate prohibition when there is a risk 

of minor injury from electrical shock or other 

source if the product is disassembled.

Used for general mandatory action precautions 

for which there is no specified symbol.
