1. Installation should be carried out according to the specified position, so as not to affect the performance of the action. In the installation of leakage protector with short circuit protection, it is necessary to ensure that there is enough arc distance in the direction of arc ejection.

2. Pay attention to the working conditions of the leakage protector. When it is used in the environment of high temperature, low temperature, high humidity, dust and corrosive gas, necessary auxiliary protective measures should be taken to prevent the leakage protector from working normally or being damaged.

3. Pay attention to the load side and power side of the leakage protector. When the leakage protector is marked with the load side and the power side, it should be wired according to this provision, and it should not be connected in reverse.

4. Pay attention to the distinction between the main circuit and auxiliary circuit terminal. For leakage protector with auxiliary power supply, we should pay attention to which terminals of the main circuit and which terminals of the auxiliary circuit can not be connected wrong when wiring.

5. Pay attention to the distinction between neutral and protective lines. For the power supply line with the protection line, the neutral line and the protection line should be strictly distinguished. When wiring, all the working phase lines (including the neutral line) must be connected to the leakage protector, otherwise, the leakage protector will produce the wrong action. And all the protection line (including the protection of zero line and ground line) must not be connected to the leakage protector, otherwise, leakage protector will appear to refuse to move the protection phenomenon. Therefore, the neutral line and the protection line can not be used together through the leakage protector.

6. Leakage protection device leakage, overload and short circuit protection characteristics are adjusted by the manufacturer, the user is not allowed to adjust.

7. Before use, the test button should be operated to check the action function of the leakage protector. Only when it can be normally operated can it be put into use
