3500 SERIES / POWER SELECTION
Power the rack. Match the input.
The family name is only the starting point. Check the supply, the PIM and the installed generation as one selection decision.

Understand the rack power arrangement
The 3500 system monitors and protects critical rotating machinery. Its power arrangement needs to be considered alongside the monitoring rack, not as a general-purpose plant power supply. Start with the installed equipment record and the 3500 machinery protection range.
A rack can use one or two 3500/15 supplies. With two installed, the arrangement provides redundancy: the lower supply is primary and the upper one is the backup. Redundancy does not eliminate the need to review the upstream source, wiring, alarms and maintenance history.

03 / SUPPLYExact 3500/15
04 / SYSTEMInstalled rack
For a turbine, compressor or pump train, record which rack serves which machine and how a power fault affects operations. A spare should be assigned to that documented configuration. A second supply is not a substitute for a site-approved maintenance plan.
02
Separate current inputs from legacy hardware
The current manufacturer datasheet lists these input ranges. They must not be applied indiscriminately to older part numbers.
The Power Input Module is a separate reference. Manufacturer documentation distinguishes current supply/PIM combinations from legacy combinations; current AC and DC sets are not compatible with the corresponding legacy sets.

In particular, 129486-01 identifies a supply, not its PIM. Treat this table as a reference check, not authorization to alter an installed rack. Verify the complete ordering code, approvals and applicable document revision with the responsible engineer.
If your enquiry concerns a newer DC reference, the 114M5329-01 catalogue entry can help identify the item being requested. A catalogue match does not prove that it can replace a different installed assembly.

Build a useful maintenance and spare-parts record
Before a replacement enquiry
Retain label photographs, the supply and PIM references, rack details and relevant fault history. Include the installed input source and environmental requirements. Let qualified personnel determine the fault and any required checks.
Before purchasing a spare
Request photographs of the offered unit, its declared condition, included accessories and available inspection records. Agree the scope of any functional test, storage requirements, warranty and dispatch timing in writing.
Rank spares by the consequence of an outage, the number of matching installed units and realistic replenishment time. Use Moore Automated’s EOL spare-parts planning guide to organize the purchasing discussion. Do not infer manufacturer lifecycle status or immediate availability from an online listing.

Q&A
Frequently asked questions
01Can every 3500/15 accept both AC and DC?
No. AC and DC are different hardware options within the family. Select the exact supply and associated input hardware for the documented installation.
02Is 127610-01 the same as universal AC?
Do not treat these references as equivalent. Obtain the installed unit’s label and version-specific documentation before specifying its replacement.
03Is 129486-01 a Power Input Module?
No. It is a legacy high-voltage DC supply reference. The supply and PIM should be identified separately in the enquiry.
04Does a redundant rack allow unrestricted live replacement?
No. Redundancy is not a general permission to work on energized equipment. Follow the applicable instructions, site procedures and qualified engineering assessment.
05What information should I send for a quotation?
Send clear labels for the supply and PIM, rack details, quantity, required condition, delivery destination and deadline. Identify any required inspection or documentation.
06Does an older part number automatically mean EOL?
No. Age or a catalogue listing is not a manufacturer lifecycle notice. Verify the status of the exact reference and confirm available sourcing options separately.
MOORE AUTOMATED / PARTS DESK
Specify a supply with confidence.
Send both the supply and PIM details. Moore Automated can review sourcing options against your documented requirements.
