Notice:

1.Relay is on the reset or set status when being released from stock, with the consideration of shock risen from transit and relay mounting, relay would be changed to set of reset status, therefore, when application (connection the power supply), please reset the relay to set or reset status on request.

2.In order to maintain set or reset status, energized voltage to coil should reach the rated voltage, impulse width should be 5 time ( more than 1 min)  should be avoided.

3.The terminals of relay without twisted copper wire can not be tin-soldered, can not be moved willfully, more over two terminals can not be fixed at the same time.

4.Relays used for metering measuring applications are usually made with dust proof structure, while most relays could be made specially per customer;s specific requirements. No longer than 6 months' storage time is recommended for this kind of relay, and please pay attention to the storage environment. To ensure contact reliability, we will keep contact status be closed when delivery if no special required by customer.
