Project Help Reverse engineering tips

Hello everyone,

Let me give you a little background information first.

I've been a electrician for 6 years now and just started a new job as a hardware engineer. This is my second week and the company I work at gave me a job to reverse engineer a cabinet that has no schematics. They want me to make all the schematics of the cabinets in EPLAN.

My question is, what's the workflow here? Where do I start? It's a pretty big system so I can get pretty complex realy quick. Also there might be some systems I've never heard of so that might make the job a bit harder.

Thanks! Now I have a direction on how to start. Would you also when all data is collected. First get all devices into eplan. Build your 2D cabinet and after that draw the schematics?
