Installation & Maintenance Notes

Mounting

• Vertical mounting only; allow 100 mm clearance above heat sinks for airflow.

• Torque mounting bolts to 4.5 Nm; ensure chassis ground connection.

Wiring

• AC Input: L1, L2, L3 (460V 3‑phase)

• DC Output: +DC, −DC (to armature/load)

• Gate Signals: To/from drive control board via 0‑51378‑19 cables.

Maintenance

• Inspect heat sinks quarterly for dust buildup; clean with compressed air.

• Check gate card connections annually; tighten terminals to 1.2 Nm.

• Test thyristor leakage every 2 years; replace if >5 mA at full voltage.
