1. Choose the right relay: When choosing a high and low voltage relay, you should choose the right product according to your needs, such as selecting according to the rated voltage, current and other information
2. Installation location: The high and low voltage relay should be installed in a dry, ventilated, non-corrosive gas, and dusty area, and the ventilation performance of the relay should be ensured during installation, so as not to affect its working temperature and life. At the same time, it should also be avoided to install the relay in the area of mechanical vibration, so as not to affect the contact state and life of its contacts.
3. Connecting line: When connecting the high and low voltage relay lines, attention should be paid to the correct and standardized wiring, and the positive and negative electrodes of the high and low voltage relays should be connected with the power supply and the controller. When connecting the line, attention should also be paid to the overload protection of the line and the isolation of strong and weak current lines to avoid the danger of electric shock.
4. Temperature: High and low voltage relays will generate a lot of heat when working, in order to avoid excessive heating, it is necessary to carry out appropriate heat dissipation measures or install fans for cooling.
5. Maintenance: Regularly inspect and maintain the relay, such as checking the contact status of the relay, refueling and other problems, and solve the problems in time if they are found.
