FAQ – 5A26137G03

1. What is the difference between 5A26137G01, G02, and G03?
   The revision suffix denotes cable length, connector configuration, or wire gauge differences. G03 features a 7-pin female connector with 6-pin adapter. Verify your power distribution panel mating connector before ordering.
2. Can I extend this cable if 3 feet is insufficient?
   Yes, with appropriate gauge-matched extension and proper strain relief. However, voltage drop must be calculated for long extensions (>6 feet) carrying high current (>5 A).
3. Is this cable required for redundant power schemes?
   Yes. Redundant Ovation power configurations use multiple distribution harnesses to route primary and auxiliary power to I/O branches.
4. What wire gauge is used?
   Typically 18–20 AWG for signal paths; 14–16 AWG for power paths. Verify exact gauge in Emerson cable specification sheet.

Installation Guide

• Step 1: De-energize power supply before connecting or disconnecting harness.
• Step 2: Route cable away from high-voltage AC cabling and motor drives to minimize EMI pickup.
• Step 3: Connect 7-pin female connector to power supply output or distribution module.
• Step 4: Use 6-pin adapter if connecting to legacy I/O base or transition panel.
• Step 5: Secure cable with cable ties every 150 mm; maintain minimum bend radius of 5× cable diameter.

Selection Tips

Order 5A26137G03 for standard 3-foot power distribution in Ovation cabinets. If you need longer harnesses, check for 5A26137G0x variants or custom cable assemblies. Always verify connector pinout matches your power supply model (1X00416H01, 1X00781H01L, etc.). Stock spare harnesses for rapid repair during power supply maintenance.
