Dear Friendly Electricians, I am an IT specialist. I am currently in a sticky situation. The company I'm working with is a digital advertising company. We have LCD screens to display ads. They asked me to install a timer on the screens. So they turn off during the night when the mall is closed. We are a company of 5 employees, and our technical guy didn't dare to install the timer. So I got local electricians, and every time they see what they are dealing with, they are saying no thank you. And the thing is I know it is a simple task. But why are they not helping? I don't know? Anyway, I want to take the mater to my hands. I do some home electrical stuff. And I worked as a computer tech for a while I install hardware and ..., so my scenario is that I have a power supply (image 1), the black and white cables are going to a 10-pin connector (image 2) and from that directly to the screens board. I unplugged the 10-pin connector, and I confirmed it is just for the screen. I want to install a Legrand timer on it to set it to turn off from 12 am till 8 am. now, if anyone wants to give me the courage to do it and give me a small tip and a "how-to," would be nice if not it is okay. Some electrician eventually will do it.
