Key Differences vs 086466-060R

• ‑060W: 4 gate boards (for redundancy / parallel drive setups)

• ‑060R: 2 gate boards (standard single‑drive use)

• Form/Fit: Mechanically interchangeable; same footprint/connections

Key Features

• 60A Continuous DC: For large DC motors and high‑current loads.

• Quad Gate Boards: Built‑in redundancy, ideal for critical/parallel systems.

• Press‑Pack SCRs: High reliability for 100% duty cycle.

• Dual Heat Sinks: Efficient cooling for heavy industrial use.

• Spike Suppression: MOVs/RC networks protect SCRs from transients.

Applications

• DC Motor Drives: Conveyors, cranes, extruders, rolling mills (60A).

• Parallel/Redundant Systems: Where dual control channels are required.

• Industrial DC Power: Plating, electrolysis, heating.

• Retrofits/Spare Parts: Reliance MaxPak Plus, GV3000/6000 DC buses.

Compatible Drives

• Reliance MaxPak Plus DC Drives

• Reliance GV3000 / GV6000 (DC bus assemblies)

• ABB/Baldor‑Reliance 460V DC drive systems

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.
