U dont really have to bother bout the green as its a bell device, not electronic device that requires earthing. So he can cut off the green and roll it aside.

ya, but how when come to colour of cable? 1 red to E1, 1 red to E2, 2 blue to terminal marked AC 230V, 2 black to another terminal marked 230V? do i have to switch of main switch in db b4 do this?

ok, will try. have to turn off main switch at db b4 do that? (mean entire home no electricity)

E1 and E2 is the red cables which is the switch of the bell. Power supply 240v is the blue and black. If thats how they wired your house lah. Neither way, best to get a multimeter to check which is the voltage. Dont assume, u might blow up the unit and black out. U dont have to turn off ur entire house supply but if u have no meter to test, then thats the only option. Buy a multimeter and keep, it will be useful in many ways for u in future

Real case...my house got a wiremen to install my doorbell...it blew up because of wrong connection.... apprently the boss ask a newbie wiremen.

The boss replaced the doorbell and install himself.

ohh. use test pen check whether got light mean got voltage right? still if know got voltage u still need to switch off main switch? since we can't contact v copper wire?

by the way, blue and black can be in either terminal?

Yes blue and black can be in either terminal. Same goes to red. Test pen can only test for live wire, neutral u cant test. Thats why u need a meter.

ohh, noted. I use test pen just now. red wire the test pen will light up. the rest no light up. so I should switch off main switch in db, then 1 red to E1 and the other red go to E2, then 2 blue go AC terminal, 2 black go another AC terminal.

then switch on main switch and press bell. kaboom?

go open up the switch for the doorbell outside your house and see what color of the wire it's connected to..

ohh, good idea mang.

ok, so it was blue!!! so it is not red wire the switch wire that suppose to fix into E1 and E2. almost kaboom my house

Exactly why i wondered why your live and neutral diff color. Usually live and neutral is red and black. So hook the blue to the switch, red and black to the incoming power. Boom. Done.

If ure too worried, test the black and red to a light bulb. See if it works. If it works, then thats the correct power cables loh

connect as below




at the doorbell thr see if got write which one neutral which one live or not, live connect red, neutral connect black
