Hi guys! First post here but long time lurker. I am a mechanical engineering working on my first complex free lance project designing and building a custom positioning machine that will see loads in excess of 200 lbs along a 7 foot vertical span. The structural and mechanical portion of my design came easy, as expected, but I am still uneasy about all the proper techniques when it comes to design and manufacture of the electrical panel (enclosure).
Some specs of the machine:
120V AC to (2) DC sources
DC1 is a 84V 12A unregulated source powering the DC motor driver and motor. DC2 will be a 24V 5A DC source for the motor controller, control circuitry, switches, pneumatics (for custom brake), lights, ect..
The question I have, even after months of intense research, is what are the best practices for grounding the separate AC & DC components INSIDE the enclosure (with Very limited real estate) and EXTERNAL DC sensors (10 of them)? This machine will be used in a public setting so safety is my number one concern.
Thanks!
