Installation & Maintenance

Mounting

• Vertical only; 100 mm clearance above heat sinks.

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

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

• Clean heat sinks quarterly (compressed air).

• Check gate board connections annually (1.2 Nm torque).

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