Safety Precautions

Be sure to read the precautions for all models in the website at the following URL: http://www.ia.omron.com/.

Warning Indications

Meaning of Product Safety Symbols

 

!

WARNING

Electrical shock may occasionally cause serious injury. Confirm 
that the input voltage is OFF before starting any wiring work and 
wire all connections correctly.

 

!

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.

 WARNING

Indicates a potentially hazardous 
situation which, if not avoided, will result 
in minor or moderate injury, or may result 
in serious injury or death. Additionally, 
there may be significant property 
damage.

 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.
