@EdSavoie Even if you rudely hot swap modules under full load, in theory, many dimmer modules are designed such that the shorter length control contacts break before and make after the physically longer primary and load contacts thus causing the dual-SCR's, TRIACS or IGBT's to cease conduction the moment the next zero crossing point comes along and prior to the heavy power contacts arcing under load.
Yes; BUT...
@starksk is speaking for ETC. The modules were/are designed to be hot-swappable, but again the old adage applies: Just because one CAN, doesn't mean one SHOULD.Because of NFPA 70E, and its regulations on arc-flash potential, we [ETC] cannot recommend hot-swapping any dimmer module while the rack is powered on. We strongly recommend that you power off the rack before swapping modules to prevent the potential for an arc-flash incident.Another quick question, are the original Sensor D20s hot-swappable, or do I need to power down the rack?
@derekleffew @EdSavoie Certainly never in public on Control Booth!I do not, sir!
