Shielded cable question.

[Izabella]

Hello, and thank you for reading this!

I have a question regarding a shielded cable grounding.
I need to wire double shielded cable and eventhough the manual instructions are quite straigh forward I'm not sure what to do. Theres 8 wires inside it and one of them is optic fiber. The fiber wire is assigned to functional earth/shield. To ground the device I'd just connect the shield to the grounging in the control box. What should be grounded: shield, optic fibre or maybe both?

Or am I getting it completly wrong?

The cable will be connected to SICK S300 mini safety scanner, if that changes anything.

I hope someone can help to educate me a little

Thank you in advance!

Cool video. I think my ex girlfriend has one of them.

I may have missed something here, but optical fibre doesn't need electrical shielding nor does it connect to any electrical terminal.

Can you share a link to some form of technical spec for the cable you are using?

You're getting something confused as fibre isn't influenced by electrical noise and wouldn't normally have a shield

It’s either a multi core cable, with one of the cores being fibre, or it’s a multi core cable with a filler wire that the OP mistakenly believes is a fibre optic cable.

Turns out the fibre was only there to give the cable more strength. Thank you very much!
