Carlos, Over the years, I have designed and built a lot of this type of equipment. It is actually easier to build in safety with this type of equipment rather than a commercial product because component costs are not as much of a factor. Here are a few rules to follow:
Identify and list all possible safety hazards - make a checklist Use appropriate connectors for the voltages and currents involved Use CE marked components wherever possible Make sure that all SELV wiring is physically separate from non-SELV wiring Use additional insulation over non-SELV wiring whenever possible Secure all wiring against coming loose inside the enclosure Securely fasten all hot or heavy components within the enclosure Clearly label any potential hazards - If necessary, label as "For Use Only By Trained Operator" Securely fasten all access covers with appropriate fasteners - use special tamper-resistant fasteners if required - label all covers "Do Not Remove - Service To Be Performed Only By Specially Trained Personnel" Finally, make sure that all safety issues on the checklist have been properly addressed If all of the above are properly done, you should have safe test fixtures which no safety inspector should have any problems with. One more thing, be sure to properly document all test fixtures, and keep copies on file. I hope this helps some, Scott Lacey --------- This message is coming from the emc-pstc discussion list.
