Sensor 3 ThruPower Modules cannot fit into DRd enclosures.
Explanation of Issue
ThruPower modules were designed to fit into Sensor3 rack enclosures. They are slightly deeper than other modules, making them too deep to fit into a DRd enclosure.
Additionally DRd was designed as an architectural dimming system, with the expectation that these architectural systems will not change as often as a theatrical system and do not require as much flexibility.
