1. performance will not be guaranteed.
2. Please add surge protection in parallel if an inductive load (L/R＞1ms）is applied.
3. Contact resistance may increases if a relay is operating without a load.
4. Please connect the terminals correctly.Any wrong connection may cause circuit damage such as malfunction,overheat,and fire.
5. Screwing-tightening condition：A) M4 Screw:1.8Nm~2.7Nm（Tightening torque for fixing relay body）B) M5 Screw:3Nm~4Nm（Tightening torque for contact terminal）
6. Use the suitable wires or busbars according to the current.Carrying current:50Amps:diameter of 16mm² (min.).
7. Standard operation condition:temperature-40℃~85℃,humidity5%~85%R.H..
8. If the relay is dropped,it should not be used again.
