Since effectiveness of the heat radiation is decreased when multiple SSRs are installed closely, please supply less than
50% of the rated load current.

Proper Usage
Cautions during use
SENSORS
1. Follow instructions in ‘Cautions during Use’. Otherwise, it may cause unexpected accidents.
2. 4-24VDC, 4-30VDC 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 specification with the used rapid fuse.
6. Install dummy resistance in parallel with the load, to keep the sum of current flowing in the load and dummy resistance
being over SSR minimum load current.
7. When using random turn-on model for phase control, install noise filter 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 ‘Specifications’)
② Altitude max. 2,000m
③ Pollution degree 2
④ Installation category II
