Legacy input characteristics

  • Input range: 175 to 264 Vac rms.
  • Application: rear input module for the legacy High Voltage AC supply.
  • Rack role: routes field AC power into the selected supply position.
  • Status: official transition material identifies the part as Phase Out.

Document the installed supply and wiring before removing the legacy module.

Migration requirements

  • Replacement type: Universal AC Power Input Module.
  • Supply pairing: use the matching Universal AC Power Supply Module.
  • Scope: replace the legacy supply and PIM together.
  • Rack check: confirm primary or secondary power position.

A PIM-only substitution is not the documented migration path.

Service precautions

  • Power isolation: de-energize the rack input before service.
  • Voltage check: verify the connected source is within the documented range.
  • Approval review: retain site-required rack approvals.
  • Wiring record: label line and neutral conductors before migration.

Follow the official 3500/15 installation and maintenance instructions.

Description

Bently Nevada 125840-01 is the legacy High Voltage AC Power Input Module for the 3500/15 power-supply system. Its documented input range is 175 to 264 Vac rms.

The PIM mounts behind the associated AC power-supply module and brings field power into the rack. Official transition information identifies this configuration as Phase Out.

A migration requires both the Universal AC supply and its matching Universal AC PIM; the replacement should be checked against rack wiring and approvals.
