Disconnecting and Reconnecting Wires on an Unfamiliar Connection Panel.

[FrodoOne]

One question is "What is this Connection Panel"?

It seems to be what might be termed a Low Voltage (Mains) "Patching Panel",
but I can find no reference to any device of that name - although similar objects "turn-up" as Photos, when one does a search.

However (more to the point),
how does one disconnect and re-connect any of the conductors?
(While it appears that one should move the "Tabs" below/above the connections down or up as the case may be, this does not seem to work.)


This device is within the "controller" of an industrial roller door.


Can anyone offer any assistance in this matter?


Also, can anyone supply a reference to this type of device and to its manufacturer?

Looks like pressing the grey bit in the square above and below where the cables are connected might release them.
Try experimenting with an unused space.

These are individual connectors fixed onto a DIN rail. Wago makes them, as do a few others. Unfortunately I can’t remember their name off the top of my head.

slide small screwdriver in the hole and the wire should be free to pull out.

They use a square profile, plastic tool, where the 'nose' is chamfered, to allow the lever to be released. You should be able to manage, using a suitable size of screwdriver, pushed in the square hole, adjacent to where the wire fits.

I believe it is this style: https://www.supuelectric.com/din-rail-terminal-block-2-5mm-2pole-double-layer-product/

It specifies a screwdriver, I use a 2.5mm flat blade.
