Please read the following safety considerations before use.

Safety Considerations

Please observe all safety considerations for safe and proper product operation to avoid

※

hazards.

symbol represents caution due to special circumstances in which hazards may occur.

※

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

Warning
Caution

Warning

1. 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 re, personal injury, or economic loss.

2. Install on a device panel to use.

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

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

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

4. Check 'Connections' before wiring.

Failure to follow this instruction may result in re.

5. Do not disassemble or modify the unit.

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

Caution

1. Use the unit within the rated specications.

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

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

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

3. Do not use the unit in the place where ammable/explosive/corrosive gas, humidity,

direct sunlight, radiant heat, vibration, impact, or salinity may be present.

Failure to follow this instruction may result in re or explosion.

4. Keep metal chip, dust, and wire residue from owing into the unit.

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

5. Since leakage current still ows right after turning off the power or in the output OFF

status, do not touch the load terminal.

Failure to follow this instruction may result in electric shock.

(green)

※

When installing multiple SSRs, please keep space between SSRs for heat radiation.
When installing SSRs horizontally (input part and output part on the same height), please
supply less than 50% of the rated load current.

※

The above specifications are subject to change and some models may be discontinued
without notice.

※

Be sure to follow cautions written in the instruction manual and the technical descriptions
(catalog, homepage).

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

Cautions during Use

1. Follow instructions in 'Cautions during Use'. Otherwise, it may cause unexpected accidents.

2. 4-30VDC signal input should be insulated and limited voltage/current or Class 2, SELV
power supply device.

3. Attach a heat sink or install the unit in the well ventilated place.
To attach the heat sink, use Thermal Grease as below or that of equal specication.

※

Thermal Grease: GE TOSHIBA (YG6111), KANTO-KASEI (FLOIL G-600),

4. Ground to the heat sink, panel, or DIN rail.
Failure to follow this instruction may result in electric shock.

5. While supplying power to the load or right after turning off the power of the load, do not
touch the body and heat sink.
Failure to follow this instruction may result in a burn due to the high temperature.

6. In order to protect the product from the short-circuit current of the load, use rapid fuse of
which I2t is under the 1/2 of SSR I2t. When short-circuited, replace the fuse to those of same

specication with the used rapid fuse.

7. Install dummy resistance in parallel with the load, to keep the sum of current owing in the

load and dummy resistance being over SSR minimum load current.

8. When using random turn-on model for phase control, install noise lter between the load

and the power of the load.

9. Do not use near the equipment which generates strong magnetic force or high frequency
noise.

10. This unit may be used in the following environments.
