More Information

Overview Manuals Power Configuration Cabinet Matching Service Checks Product Applications

Features:

  • Cabinet role: dedicated field-power conversion within the INFI 90 AC Modular Power System.
  • Configuration boundary: the input selection must match the installed power-entry arrangement before energization.
  • Replacement path: manufacturer documentation identifies IEPAF02 as the controlled successor to IEPAF01.
Its purpose is to feed field-power circuits, so a loss of output must be diagnosed across the cabinet power path rather than treated as a controller fault.

The documented IEPAF01 replacement route does not remove the need to match the host cabinet, connectors, and power-entry hardware.

Input configuration, grounding, upstream protection, and connected load determine whether the module can be energized safely.

Apter Power provides exact-model document review, quotation, and procurement support for the ABB IEPAF02 AC Field Power Module.

  • Input selection: configure the documented 120 or 240 VAC arrangement.
  • Output: 25.8 VDC field power.
  • Capacity: maximum 4 A and 102 W.
  • Module position: one power-module slot in the documented cabinet arrangement.
  • System: verify the INFI 90 AC Modular Power System cabinet.
  • Power entry: match the installed panel, upstream protection, and supply.
  • Replacement path: IEPAF02 is documented as the compatible replacement for IEPAF01.
  • Boundary: confirm connector, bus, and cabinet-version details before service.
  • Isolation: de-energize and verify the mains-powered cabinet under site procedure.
  • Configuration: confirm the input jumper arrangement before insertion.
  • Load check: inspect downstream field circuits for faults and total demand.
  • Acceptance: verify field voltage and cabinet indications before reconnecting dependent circuits.
  • INFI 90 field power: 25.8 VDC supply for field-powered cabinet circuits.
  • AC Modular Power System maintenance: exact-module service in the documented cabinet architecture.
  • IEPAF01 replacement: controlled migration where the manufacturer compatibility statement and cabinet checks both apply.
Description
IEPAF02 is a Bailey INFI 90 AC field power module documented for the AC Modular Power System. The manufacturer manual identifies selectable 120 or 240 VAC input arrangements and a 25.8 VDC field-power output rated to 4 A, or 102 W maximum.

The manufacturer manual identifies IEPAF02 as the compatible replacement for IEPAF01 and describes a single power-module slot. That replacement statement still requires the installed cabinet, power-entry panel, input selection, and connector arrangement to be checked before service.

Because IEPAF02 connects to mains-powered cabinet hardware, qualified personnel should isolate the power system before removal. Verify the input jumper arrangement, grounding, downstream field load, and cabinet documentation before energizing the replacement module.
Technical notes
IEPAF02 uses a cabinet-specific input selection for the documented AC supply arrangements. Copying a jumper position from another cabinet can expose the module and field-power path to the wrong mains configuration. Keep the system isolated until the power-entry record, physical jumper, grounding, and connector arrangement agree.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
How should the AC-input selection for IEPAF02 be controlled when two cabinets use different mains supplies?
Use the installed cabinet supply and manufacturer jumper arrangement for that cabinet; do not copy the setting from a neighboring system. Connection should stop if the power-entry record and physical jumper position disagree.
Can IEPAF02 replace an installed IEPAF01 without checking the surrounding AC Modular Power System?
The manufacturer documents the replacement path, but the cabinet version, connector arrangement, input selection, grounding, and field load still define whether the exchange is valid for the installed system.
Before IEPAF02 is energized, how should the downstream field-power demand be assessed?
Compare the connected circuits and expected startup demand with the documented output boundary, and investigate any ground fault or abnormal load first. Energization should wait if the load record is incomplete or exceeds the cabinet design.
Why should the power-entry panel record accompany an IEPAF02 service request?
It establishes the incoming supply, isolation boundary, upstream protection, and cabinet arrangement needed to interpret the module’s input selection and connector context.
If IEPAF02 is installed but field power remains absent, which diagnostic path avoids an unnecessary second replacement?
Check the selected AC input, upstream protection, grounding, cabinet connector and bus, downstream faults, and local indications in that order. Correct an external power-path issue before changing another module.
What evidence should be supplied when requesting IEPAF02 for a cabinet with an unexplained power loss?
Provide the module label, cabinet and power-entry panel identities, supply record, jumper position, connector photos, downstream-load information, and the observed fault sequence so identity and power-path scope can be reviewed together.
