1.Before installing,you must cut off the power supply,don't operate in the charged state.

2.We suggest a fuse or automatic circuit breaker should be connected in series before the lightning proof module.

3.In installing, please connect with the installation diagram,as shown in diagram,"+"represents the anode wire,"-"Represents the cathode wire,PE represents the earthing wire,the wrong connection is unallowable.After the installation is finished,turn on the switch of automatic circuit breaker(or fuse),to check whether the working state is normal or not.

4.After the installation is completed,insert the module properly,and check whether the lightning proof module works normally or not.

5.In the period of using the lightning proof module,inspect,test and view the fault display window state regularly,when the fault display window is red or the remote-signalling terminal outputs the alarm signal,this means the lightning proof module has the fault,you shall repair or change it in time.

6.The parallel power lightning proof module shall be installed in parallel,the wire shall be short,thick and straight,connected firmly and reliably.
