4. Installation & Redundancy
• Slides into dedicated power slots at rear left of 3500 rack; captive screws secure module
• Requires 0.8 N·m torque on power lugs; accepts 12 AWG max wire size
• Dual-supply wiring: lower slot = primary, upper slot = backup; both units share load in parallel during normal operation
• Uses 133300-01 Power Input Module (PIM) for AC/DC front-end conditioning if 20–30 VDC source is not available
• Fuse replacement: 01720045 (5 A, 250 V, fast-acting) accessible without removal of module
• Firmware and calibration data stored on-board; no external PROM required
