Hey everyone...
Fred over at OSLS sent me this and i think it will be very useful to some of you.
Proper wiring of a safety shutter per FDA regs. this also addresses the "boing" effect i think randy asked about a couple months ago.

***NOTE***
The 5VDC Power supply that is listed in these pictures are what is INCLUDED in the CDRH certified projectors in which OSLS sells. Be sure that your PS can handle the current needed to wire your individual shutter actuator!
