  1. UL certification for 24V DC nominal. Rockwell Automation specified 18 32V DC.
  2. The combination of all output power (5.1V backplane, 24V backplane, 3.3V backplane, and 1.2V backplane) cannot exceed 75 W.
  3. The hold-up time is the time between input voltage removal and DC power failure.
  4. Use time-delay type overcurrent protection in all ungrounded conductors.
  5. This fuse is intended to guard against fire hazard due to short circuit conditions.
  6. Use this conductor category information for planning conductor routing as described in the system level installation manual.
