1. Please use relays in the conditions described in the specification. Otherwise product performance will not be guaranteed.
2. Please add surge protection in parallel if an inductive load (L/R>1ms)is applied.
3. If the relay operates on no load condition,the contact resistance may increase.
4. Please connect the terminals correctly.Any wrong connection may cause circuit damage such as malfunction,overheat,and fire.
5. Screwing-tightening condition: M3 Screw:0.8Nm~1.3Nm(Tightening torque for fixing relay body).
6. Use the suitable wires or busbars according to the current.Carrying current:20Amps:diameter of 4mm2 (min.). 
7. Standard operation condition:temperature -40℃~85℃, humidity 20%~90%R.H..
8. If the relay is dropped,it should not be used again.
