Matters needing attention
1. During installation, sensors and electrical connectors should be well protected, and it is strictly prohibited to fall or collide;
2. After the installation and connection of the sensor are completed, the wiring should be checked for correctness and confirmed before power can be transmitted to avoid damage caused by strong electricity mistakenly connecting to the sensor;
3. When the storage period of the sensor exceeds 1 year, the temperature resistance value and insulation resistance value of the sensor should be tested before installation to ensure good sensor performance;
4. The scrapped sensors should be properly disposed of to avoid any impact on the environment.
