Bit too far I think
Here's a few things to keep in mind;
1. Use a proper metal electrical panel with backplate
2. The size of the panel is not the space you get, it's how big the backplate is and the distance it is from the inside of the door.
3. Two items are sort of fixed, terminals across the bottom or up one side, a door mounted isolator positioned along the edge of the door that opens.
4. Use CAD to draw rectangles representing the guts of the enclosure, i.e. backplate, terminal rail, door isolator, drivers, power supplies, bob + interfaces, fuses/circuit brreakers, relays, trunking, vfd, etc.
5. Just drag the rectangles about to get the best layout, the space you need is going to be bigger than you think.
6. Obey any rules regarding ventilation, and keep large transformers away from sensitive items like the bob
7. Use the cable trunking to route power cables in one and signal cables in the other.
8. The backplate will have an earth point, use this as your earth star point, you can use the DIN rail mounted earth terminals I used to make life easier.
9. Use proper terminating glands for the type of cable you will be using
10. Get a crimping tool and some bootlace ferrules, cable number markers make a better job too.
11. Use tri rated single core cables inside the panel, check the standard colours for panels used in your area, e.g. here it's black for AC power, blue for 24 DC, etc.
12. Make provision for cooling fans, ideally some blowing in and some sucking out. The ones sucking in should draw air through a replaceable filter, you need to keep a higher pressure inside
the panel so dirt is not sucked in through gaps.
13. Use DIN rail to mount everything.
14. Use quite deep trunking, it fills up quickly.
15. there must be moreLast edited by EddyCurrent; 27-01-2015 at 11:07 AM.
