The installation of protector of leakage of electricity should accord with the requirement of manual of manufacturer home product. 2.
The protector of leakage of electricity that mark has power source side and bear side must not be received instead. If receive,turn over, meet those who bring about protector of electronic type leakage of electricity take off buckle coil to cut off and cannot cut off the power along with power source, as a result is long electrify and burn down. 3.
Protector of installation leakage of electricity must not be demolished or forgo original safe preventive measure, protector of leakage of electricity can defend as electric safety only the add safeguard in the system. 4.
When installing protector of leakage of electricity, must distinguish strictly neuter line and protective route. Use triode 4 lines type and 4 extremely when protector of leakage of electricity of 4 lines type, neuter line should receive protector of leakage of electricity. The neuter line that passes protector of leakage of electricity must not regard protection as the line. 5.
The job 0 lines must not emphasize particularly on in bear of protector of leakage of electricity answer ground connection, otherwise protector of leakage of electricity cannot work normally. 6.
Use the spur track of protector of leakage of electricity, its work the 0 lines that 0 lines can regard this loop as only, prohibit working with other return circuit 0 lines are linked together, the job that other line or equipment also cannot use the circuitry after already using protector of leakage of electricity or device 0 lines. 7.
After installation is finished, should according to " build quality of electrician Cheng construction to check and accept a standard (GB50303-2002) 3.
1.
6 clauses, namely " the protector of leakage of electricity of motivation and gaffer Cheng should do imitate movement to experiment " requirement, have a test to protector of finishing leakage of electricity, in order to assure its sensitivity and dependability. Experiment pushbutton can be operated 3 times when the experiment, take bear cent to close 3 times, affirm the movement is not had correctly by accident, type investment uses Fang Kezheng. 4, the safety of protector of brief summary leakage of electricity runs the administrative system that should rely on an effective and measure to assure. Besides doing good periodic to safeguard, still should be opposite regularly the movement of protector of leakage of electricity is characteristic (include cost of action of leakage of electricity and behavioral time, leakage of electricity not value of behavioral electric current) have a test, had done detect record, compare with the numeric photograph when installation is initiative, judge its quality to whether have change. In use should use protector of leakage of electricity according to the requirement of operation instruction handbook, check every months by the regulation, operate the experiment pushbutton of protector of leakage of electricity namely, check its to whether can disconnect normally power source. The time that should notice to operate experiment pushbutton when the examination cannot too long, it is advisable to be moved in order to nod commonly, frequency also cannot too much, lest burn down is in-house component. In use of protector of leakage of electricity produces tripping operation, when discovering switch movement reason via the examination, allow to try power transmission, if again tripping operation, should prove a cause, find out breakdown, must not successive forcibly power transmission. Protector of leakage of electricity once when attaint cannot be used, answer to ask major to electrician undertakes checking or change instantly. If protector of leakage of electricity produces misoperation and refus action, its reason is by protector of leakage of electricity itself is caused on one hand, it is the cause that comes from circuit on the other hand, should seriously concrete analysis, privately disassembles and do not adjust the in-house parts of an apparatus of protector of leakage of electricity.
