5. Installation & Configuration Guide

Stage 1: Pre-Installation Preparation (10–15 minutes) ⚠️ Safety First: Lock out/tag out drive power, verify zero energy state, wait for capacitor discharge. Tools Required: ESD strap, screwdriver, multimeter. Data Backup: Document wiring and settings.

Stage 2: Removing the Old Module (5–10 minutes)

1. Disconnect power and signal cables.
2. Label connections.
3. Remove module from rack.
4. Inspect connectors. ⚠️ Note: Keep old module for reference.

Stage 3: Installing the New Module (10 minutes)

1. ESD safe. Verify model match.
2. Insert into slot and secure.
3. Reconnect wiring per diagrams. Self-Checklist: [ ] Secure mounting, [ ] Wiring correct, [ ] Terminals tight.

Stage 4: Power-On & Testing (15–30 minutes) Pre-Power Check: Measure voltages, check for shorts. Power-On Steps:

1. Energize control power.
2. Monitor status indicators.
3. Verify gate supply output.
4. Test drive operation under no-load.

⚠️ Troubleshooting Note: No output may indicate input power or fuse issues. Use drive diagnostics for faults.
