᜸ Warning

  

Failure to follow instructions may result in serious injury or death.

01. 

Fail-safe device must be installed when using the unit with machinery that 

may cause serious injury or substantial economic loss. (e.g. nuclear power 

control, medical equipment, ships, vehicles, railways, aircraft, combustion 

apparatus, safety equipment, crime / disaster prevention devices, etc.)

Failure to follow this instruction may result in personal injury, economic loss or fire.

02. 

Do not use the unit in the place where flammable / explosive / corrosive gas, 

high humidity, direct sunlight, radiant heat, vibration, impact or salinity 

may be present.

Failure to follow this instruction may result in explosion or fire.

03. 

Install on a device panel to use.

Failure to follow this instruction may result in fire or electric shock.

04. 

Do not connect, repair, or inspect the unit while connected to a power source.

Failure to follow this instruction may result in fire or electric shock.

05. 

Check ‘Connections’ before wiring.

Failure to follow this instruction may result in fire.

06. Do not disassemble or modify the unit.

Failure to follow this instruction may result in fire or electric shock.

᜸ Caution

  

Failure to follow instructions may result in injury or product damage.

01. 

When connecting the power / measurement input and relay output, use 

AWG 24 (0.20 mm

2

) to AWG 15 (1.65 mm

2

)cable or over and tighten the 

terminal screw with a tightening torque of 0.98 to 1.18 N m. 

 

Use the wiring suitable for the load current capacity.

 

Failure to follow this instruction may result in fire or malfunction due to contact 

failure.

02. 

Use the unit within the rated specifications.

Failure to follow this instruction may result in fire or product damage. 

03. 

Use a dry cloth to clean the unit, and do not use water or organic solvent.

Failure to follow this instruction may result in fire or electric shock.

04. 

Keep the product away from metal chip, dust, and wire residue which flow 

into the unit.

Failure to follow this instruction may result in fire or product damage.

Cautions during Use

• 

Follow instructions in ‘Cautions during Use’. 

 

Otherwise, It may cause unexpected accidents.

• 

Power supply should be insulated and limited voltage / current or Class 2, SELV power 

supply device.

• 

Install a power switch or circuit breaker in the easily accessible place for supplying or 

disconnecting the power.

• 

Use twisted pair wire for communication line.

• 

Keep away from high voltage lines or power lines to prevent inductive noise.

 

In case installing power line and input signal line closely, use line filter or varistor at 

power line and shielded wire at input signal line.

 

Do not use near the equipment which generates strong magnetic force or high 

frequency noise.
