Proper Usage
Make sure do not touch the heat sink or the unit body while power is supplied or right after load power is
turned off. If not, it may cause a burn.
High temperature caution
Caution for using

1. Attach a heatsink and ventilate for smooth convection current. If not, congested heat transfer may cause product failure
or malfunction.
2. For mounting multiple SSR, please keep certain installation intervals for heat prevention. For horizontal installation (when
the heights of input part and output part are equal), it is recommended to apply less than 50% of the rated load current.
3. Make sure do not touch the heatsink or the unit body while power is supplied or right after load power is turned OFF.
If not, it may cause a burn.
4. Connect the proper cable for the rated load current with output terminal.
5. Use rapid fuse of which I
2
t is under 1/2 of SSR I
2
t in order to protect the unit from load's short- circuit current.
6. In case of a short-circuit please replace the fuse with a 1/2 of SSR I
2
t value specified semiconductor protective type.
7. In case that load's current is lower than SSR min. load current, connect dummy resistance to the load in parallel so as to
make load's current higher than SSR min. load current.
8. When selecting phase control with random turn-on model, install the noise filter between load and load's source.
9. Make sure that the screw on output terminal is tightly fastened. Using the unit with loose bolt may cause product failure
or malfunction.
10. Do not touch the load's terminal even if output is OFF. It may cause electric shock.
11. The signal input of the 4-30VDC model should be supplied by the insulated and limited voltage/current or by Class 2
power supply.
12. Proper application environment (Avoid following environments to install)
①
Where temperature/humidity is beyond the specification
②
Where dew condensation occurs due to temperature change
③
Where inflammable or corrosive gas exists
④
Where direct rays of light exist
⑤
Where severe shock, vibration or dust exists
⑥
Where near facilities generating strong magnetic forces or electric noise
