1. Pre-Intervention Electrical Safety Protocols

!High-Voltage Safety Protocol & DC Bus: Wait at least 5 minutes after power cutoff to allow inverter DC bus capacitors (380V DC) to bleed down.
!Verify 0V DC across inverter filter capacitors before unplugging motor harness connectors.
!Keep hands clear of drive belt and pulleys during any manual rotation tng.

3. Preliminary Mechanical & Visual Checks

Slip off drive belt and spin drum/motor shaft by hand to check for roaring or seized ball bearings.
For universal motors: verify carbon brushes have at least 10mm remaining length and smooth contact faces.
Inspect motor suspension rubber mounts and drive belt tension/groove profile.
