Your assumption was correct, it is wiring for a machine. All of our wires will be labelled with cable markers, therefore it wouldnt be a problem using the same colour. Are you allowed to use a different colour (excluding colours already designated for other purposes)? Or should I just go with...
My question is regarding conductor colour for 0vdc. I have 60204-1, which states that DC control ccts be blue. Does this imply that the 0vdc should be blue as well? The north american wiring we do always identifies them with different colours, but for European control wiring I would like to...
I am looking for a guide or examples of reference designations for electrical control circuits. I have the standard 1346-1, but I wanted something to help with my understanding of it.
Any help would be greatly appreciated.
Thank you for your answers.
This is a disconnect for a control panel on an industrial machine, not a generator/transfer switch application..(I should have been more specific). In reality, the neutral will not be used because the loads are either three phase, or 24vdc. I'll have to get more...
I am trying to determine whether you are required to disconnect the neutral conductor as well as the lines in a 4 wire distribution system (Poland).
It would be much appreciated if someone could point me in the right direction.
Thanks.
My question is in regards to the EMC directive with respect to CE compliance.
First of all, I would like to determine if the EMC directive applies to us, and in what manner;
and secondly what we have to do to meet the requirements of the directive.
We design and manufacture automation equipment...
I'm located in Southern Ontario, Canada. I'm willing to do whatever it takes to implement this system, as it will have great impact(specifically cost savings...) on our future product manufacturing/developing.
Our local siemens rep. is apparently working on it, but he confesses a lack of...
So for practical purposes, I would test all the wires before they are terminated? What we do is build and wire the backplate's for the panels on a bench, and then install them into the cabinets when complete. We then do the remote wiring and terminations. But by what you are saying, we dont...
I have some questions regarding hi-pot testing of equipment.
We manufacture automation equipment and are looking in to hi-pot testing the control panels and control system. My question is what needs to be tested...
The control panels consist of contactors, relays, disconnects, inverters, plc's...
I've been in contact with our distributor, but this is apparently above them. They are looking in to getting some more help from siemens. One thing i dislike is haveing to go to distributor level for tech support..they inevitably need to go to a higher level, and sometimes things get lost in...
