6 Use
Before energizing the relay, confirm whether the voltage level of the connected relay is 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; if there are damaged parts, Please contact us to replace it for you.
7 Ordering instructions
When ordering, please indicate the relay model specification, quantity, structure, rated voltage and other requirements.
