6 Use

6.1 Before energizing the relay, confirm whether the voltage level and current value of the connected relay are consistent with the actual parameters, otherwise the relay may be damaged; check whether the relay is damaged during transportation and storage, and the relay screw fasteners should not be loose; There are damaged parts, please contact us to replace them.

6.2 The relay needs to be wired according to the wiring diagram. Note that the polarity of the jump coil and the close coil cannot be reversed.

6.3 The initial state of the contact in the 5th wiring diagram of the relay is the state of the jump position, and the state of the contact is opposite to the initial jump state when closed.

7 Ordering instructions

When ordering, please specify the relay model, specification, quantity, structure, voltage or current value of the double coil circuit, and other special requirements.
