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. 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.
3. Check 'Connections' before wiring.
Failure to follow this instruction may result in re.
4. 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 specications.
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.

Cautions during Use
00
1. Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
2. 4-24VDC signal input should be insulated and limited voltage/current or Class 2, SELV power supply
device.
3. Install the unit in the well ventilated place.
4. While supplying power to the load or right after turning off the power of the load, do not touch the
body.
Failure to follow this instruction may result in a burn due to the high temperature.
5. 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 specication with
the used rapid fuse.
6. 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.
7. When using random turn-on model for phase control, install noise lter between the load and the
power of the load.
8. Do not use near the equipment which generates strong magnetic force or high frequency noise.
9. This unit may be used in the following environments.
①
Indoors (in the environment condition rated in ‘Specications’)
②
Altitude max. 2,000m
③
Pollution degree 2
④
Installation category II
