chassis - earth

[bloodyviking77]

Cheerio all,

Just got a nanao Kz18-en chassis repaired (came non-working with the cab I picked up for cheep).

There was no "frame" for the monitor in the cab - the tube was just bolted in to the plywood, with the chassis screwed into the inside of the cab.

As I am in Oz, (240v AC), I have a step-down iso transformer to take me down to 110v for the chassis.

I'm new to all this, so bear with me: My question is this: the primary side of the transformer is connected to a 3 prong plug (active, neutral, earth), while the secondary side just has a two-prong socket.

So do I need to connect the chassis to earth somehow? Do I just run a wire from the small metal PCB support/frame on the chassis to the transformer somehow??

I'd  appreciate any help

Cheers

basically, tie all the earth (green) together and back to the incoming earth from your power supply
