3500/15-05-05-01 specifies a Bently Nevada 3500/15 rack power arrangement with a universal AC supply in both the top and bottom slots. The final 01 code selects CSA/NRTL/C Class I, Division 2 approval.

Each installed supply can power a full 3500 rack. In a two-supply arrangement the lower module acts as primary and the upper module acts as backup, allowing either supply to be removed or inserted without interrupting the rack while the other supply remains installed.

• Two universal AC supplies provide a redundant rack-power arrangement.
• The lower slot operates as primary and the upper slot as backup.
• Either supply can individually power the complete rack.
• A Supply OK LED indicates correct operation on each power-supply module.
• No minimum rack load is required.

• 3500 machinery-protection racks that require redundant universal AC power.
• Installations using nominal 110 to 220 Vac across the documented wide input range.
• Class I, Division 2 rack configurations using the selected CSA/NRTL/C option.
• Maintenance arrangements where one supply must remain available during removal of the other.

• Keep the complete 3500/15-05-05-01 configuration because both 05 supply positions and the 01 approval suffix are significant.
• Pair each universal AC supply with the compatible universal AC Power Input Module.
• Do not mix the universal AC supply and PIM with legacy high-voltage or low-voltage AC units.
• Verify rack wiring, input voltage and both Supply OK indicators after replacement.
• A single installed supply can power the rack, but redundancy requires both configured supplies to remain serviceable.
