More Simple Questions

Hello,

I've ordered my cbus components and shortly will be in a position to start installing / wiring the cbus. As I have not done this before I would like to make sure that I do everything using best practice possible.
Are there some links I could follow with perhaps detailed installation instructions for the new and uninitiated?

CbusNetwork.jpg

The above is my proposed network.
Is my proposed topology ok? Because the power is being supplied by the din mounted dimmer units will I have a problem with voltage drop accros the network seeing how there will be considerable distance between the din mounted units and the last input on the network.

Is it necessary to purchase non din mounted power supplies and place them between the input units? Or do you use different topology to ensure that the voltage drop will be minimised?

How would you provide the network some sort of redundancy so that if for some reason the cat 5 was to break, get eaten by vermin etc etc you were able to fix the network break?

The above is how I plan to connect the units. Is this best practice?

Again thanks in advance.

 

All you ever needed to know about volt drop

Go to this page on the CIS web site scrole to the bottom and look at the doc regarding voltage drop calculation on a C-bus network. I would have posted the exact page link but for some reason I couldn't copy that one just the Tech Manual page.

 

My installer put the C-Bus cable in a loop, with both ends inside the cabinet where the output units are housed. Only one end is connected (to avoid creating an electrical loop), with the other end left coiled up and not connected.

But, should the cable break somewhere along its length, the other end can be connected aswell.

Hope that helps,

Nick
