i've installed a telephone lightning arrestor a long time ago in my house but then, a couple of days ago, lightning strikes it and the thing went dead.
so, i buy a new one (which i just found out, is rm7 cheaper on other store, goddamnit). the problem is, i yanked out the old one without looking at the wire connection coordination and now i don't know how to installed the new one.
somehow i like to save money and don't want to call any electrician yet and apparently my google is broken. anybody here can help?
picture related, it's the telephone lightning arrestor:
