Installation methods in addition to the general installation procedures for electrical equipment, the following points should be noted:

1. Installation of leakage protector shall meet the requirements of the manufacturer's product manual.

2. Leakage protector marked with power side and load side shall not be connected backwards.If the connection is reversed, it will cause the tripping coil of the electronic leakage protector can not be cut off with the power supply and power failure, so that a long time to burn.

3. Installation of leakage protector shall not remove or abandon the original safety protection measures, leakage protector can only be used as additional protection measures in the electrical safety protection system.

4. When installing leakage protector, it is necessary to strictly distinguish between neutral wire and protective wire.When using three pole four wire type and four pole four wire type leakage protector, the neutral line should be connected with leakage protector.The neutral wire passing through the leakage protector shall not be used as the protection wire.

5. The working zero line shall not be repeatedly grounded at the load side of the leakage protector, otherwise the leakage protector cannot work normally.

6. The working zero line of branches using leakage protector can only be used as the zero line of this circuit. It is forbidden to connect with the working zero line of other circuits.

7. After the installation is complete, according to the construction of electrical engineering construction quality acceptance specification clause 3.1.6 (GB50303-2002), the "power and lighting engineering leakage protector should be" do simulation test requirements, the completion of the leakage protector testing, to ensure its sensitivity and reliability. Trial operational test button three times, loading points three times, confirm the action is correct, before officially put into use.

The safe operation of leakage protector depends on a set of effective management system and measures.In addition to regular maintenance, the operation characteristics of the leakage protector (including leakage operating value and operating time, leakage non-operating current value, etc.) should be tested regularly, the detection record should be made, and compared with the initial value of installation, to determine whether its quality has changed.

In use, the leakage protector shall be used in accordance with the requirements of the operation manual, and shall be checked once a month according to the provisions. That is, the test button of the leakage protector shall be operated to check whether it can be normally disconnected from the power supply.In the inspection should pay attention to the operation of the test button time should not be too long, generally inching is appropriate, the number of times should not be too much, so as not to burn out the internal components.

Leakage protection device in the use of tripping, after the inspection did not find the cause of switch action, allow a test power supply, if the tripping again, should find out the reason, find out the fault, shall not be forced to continue power supply.

Once the leakage protector is damaged and cannot be used, it should be immediately checked or replaced by a professional electrician.If the leakage protector misoperation and rejection action, the reason is caused by the leakage protector itself on the one hand, on the other hand is the reason from the line, should be carefully detailed analysis, do not disassemble and adjust the leakage protector internal components.
