Procedures and Recommendations

Ensure the relay contact status is checked and reset if necessary after transit or mounting.
Excitation voltage should reach rated voltage without exceeding 1 minute.
Do not apply voltage to both coils simultaneously in double coil relays.
Terminals without twisted copper cable should not be tin soldered or wrenched.
Avoid using relays that have undergone electrical endurance testing.

Outline dimensions and circuit diagram Remark: The tolerance didn’t mark on drawings. When dimension is≤1mm,the tolerance should be less than ±0.2mm ; when dimension is between 1-5mm, the tolerance should be less than ±0.3mm; When dimension is ≥5mm, the tolerance should be less than ±0. 5mm. Note: 1. The default status of the relay contact is closed( Reset), it maybe change to “open” due to transit or relay mounting, please check the contact status when using, and reset the relay contact status on request if necessary. 2.In order to make sure the contact “ open” or “closed” status, the excitation...
