Overview
Configured for DC power routing and hardware interconnection in Emerson Ovation and Westinghouse control environments, the Emerson 5A26137G03 (5A26137G03 Power Cable / Distribution Harness) provides direct physical and electrical execution between associated system hardware components. The harness distributes nominal DC supply power through its cable and connector assembly while maintaining the required physical connection path for the installed sub-assembly.

DCS Power Distribution and Channel Isolation Considerations
The Emerson 5A26137G03 is used as a physical power routing assembly rather than an active signal-processing module. Therefore, its electrical installation should maintain separation between power conductors and low-level process instrumentation circuits.
In Ovation-related cabinet assemblies, 4-20 mA HART loops, FOUNDATION Fieldbus segments, and other process signals may operate within adjacent hardware. Consequently, cable routing should prevent unnecessary coupling between DC power wiring and sensitive instrumentation conductors. Where shielded wiring is specified by the associated system documentation, shield termination should follow the cabinet grounding arrangement for the installed hardware.
Frequently Asked Questions
Q: Does the Emerson 5A26137G03 require separate power consumption?
A: The 5A26137G03 is identified as a passive power cable and distribution harness. No separate power consumption value is specified for the cable assembly itself.
Q: Can the connector configuration vary between installations?
A: Yes. The available information identifies a 7-pin female connection and a 6-pin adapter arrangement that may vary according to the specific sub-assembly application.
Q: Can the cable be installed alongside low-level instrumentation wiring?
A: Physical separation should be maintained where practical. Route the power harness according to the applicable cabinet wiring practice and keep it separate from sensitive signal circuits when required.
Field Installation Guidelines
Verify the complete Emerson 5A26137G03 part number before installation and confirm connector compatibility with the target Ovation or Westinghouse hardware assembly.
Disconnect or isolate the associated DC power source before connecting or removing the harness. Inspect the cable insulation, connector housing, contacts, and strain-relief points for physical damage before installation.
Route the approximately 1 m cable without excessive bending, twisting, tension, or compression. Do not force connector engagement. Align the connector correctly and secure it according to the mechanical arrangement of the associated hardware.
Keep DC power routing separate from sensitive process signal wiring where the cabinet layout permits. Apply shielding and grounding practices specified for the connected control system hardware.
