1. 1

   Measure incoming AC supply voltage at L1, L2, L3 terminals to ensure it is stable and within the drive's specified operating range.

2. 2

   Inspect all input power and ground wiring for proper termination, tightness, and signs of damage or discoloration.

3. 3

   Inspect motor output wiring (U, V, W) and braking resistor wiring (B1, B2) for shorts, insulation damage, or loose connections.

4. 4

   Visually inspect the drive's internal components for any obvious signs of damage, such as burnt parts, loose debris, or liquid ingress (ensure power is off and follow LOTO procedures).
