Verification boundary
What still needs to match
Electrical architectureConfirm phase, starting method/capacitor requirements where applicable, voltage, frequency, current, protection, and controls.
Mechanical interfaceConfirm full frame suffix, mounting, shaft geometry, envelope, conduit-box orientation, and driven-equipment clearance.
Duty and environmentCheck actual speed, service factor, efficiency, starts per hour, enclosure, ambient/contamination exposure, and thermal duty.
Drive compatibilityFor SP4 or any controlled-speed application, verify VFD suitability and operating speed range from current Baldor-Reliance documentation.
