Hello tomearp The only piece of advise I can offer is to try this (ideally replace all terminal modules if you can). While I never had any problems with the ET200S (and used them many many many times), the connection of the terminal modules always seem to present a "challenge" to installers/electricians who are not familiar with them. What can unfortunately happen all to easily is that someone needs to add a terminal module during Panel manufacturing but is NOT aware of the "push in from the right and unlatch via the terminal module to theleft" mechanims. This then can lead to someone applyingperhaps a little bit too much force trying to lifta terminal module out (without first sliding out) and in the process damaging the backplane connections. Anyway, food for thought and perhaps worth a try inyour "process of elimination" quest. |

Anyway, while this advise is properly not helpful to solve your problem (which you seem to have narrowed down to power supply issues already), I might as well leave it here as it may help others.
