1. Product Overview

The IC697PWR748D is a high‑reliability, 90W power supply module designed for GE Fanuc Series 90‑70 PLC systems. It provides regulated +5V, +12V, and –12V outputs to the PLC backplane and supports dual‑rack operation from a single unit.

2. Key Features

• Input: 35–60VDC (nominal 48VDC)

• Outputs:

  • +5VDC @ 18A (logic power)

  • +12VDC @ 1.5A

  • –12VDC @ 1A

• Total Power: 90W maximum

• Dual‑rack capable: Feed a second rack via IC697CBL700 cable

• Hot‑swap ready: Replace without system shutdown

• Diagnostic LEDs: Power (green), Fault (red)

• Protections: Overcurrent, short‑circuit, overvoltage (5V clamped at 6.7V)

• Industrial grade: –10°C to +60°C operating, 5–95% non‑condensing humidity

3.2 Environmental

3.3 Mechanical

• Dimensions: 170 × 150 × 30 mm

• Weight: 1.2 kg

• Mounting: Slide‑in, leftmost slot of 90‑70 rack (48‑pin backplane connector)

4. Installation

4.1 Rack Installation

1. Ensure the rack is powered off.

2. Insert the module into the leftmost slot of the Series 90‑70 rack.

3. Push firmly until the module clicks into place (secures to 48‑pin backplane connector).

4. Tighten the front panel screws (if equipped).

4.2 Dual‑Rack Configuration

1. Use IC697CBL700 pre‑wired cable.

2. Connect one end to the secondary power port on the IC697PWR748D.

3. Connect the other end to the power input port of the second 90‑70 rack.

4. Verify total load ≤ 90W; the second rack is limited to 5V power (<5.2A).

5. Wiring

5.1 Input Power Wiring

1. Confirm input voltage is 35–60VDC.

2. Connect the positive (+) input wire to the +48V terminal.

3. Connect the negative (–) input wire to the GND terminal.

4. Torque terminals to 0.8–1.0 N·m.

5. Use 14–18 AWG copper conductors.

5.2 Grounding

• Connect the module’s chassis ground to the system’s protective earth (PE).

• Ensure low‑impedance ground path for safety and noise reduction.

6. Operation

6.1 Power‑On

1. Apply input power (35–60VDC).

2. Check LEDs:

   • Green (Power): On = normal operation.

   • Red (Fault): Off = no faults; On = overvoltage, overcurrent, or short circuit.

3. Verify backplane voltages: +5V (±5%), +12V (±10%), –12V (±10%).

6.2 Normal Operation

• The module provides continuous power to the backplane and I/O modules.

• Monitor the Power LED for steady green; Fault LED should remain off.

• In dual‑rack mode, ensure total load does not exceed 90W.

7. Protection & Diagnostics

7.1 Protection Features

• Overcurrent: Electronic limiting on all outputs; shuts down if exceeded.

• Short‑Circuit: Immediate shutdown and latched fault; reset by cycling input power.

• Overvoltage: 5V output clamped at 6.7V; shuts down if input exceeds 60VDC.

7.2 LED Diagnostics

8. Maintenance

8.1 Regular Inspection

• Monthly: Check wiring tightness, terminal corrosion, and LED status.

• Quarterly: Clean dust from module surface and rack vents (use low‑pressure air).

• Annually: Verify input/output voltages and load currents.

8.2 Troubleshooting

9. Warranty & Support

• Warranty: 1‑year manufacturer’s warranty against defects.

• Support: Contact GE Fanuc Emerson Automation for technical assistance.

10. Safety Precautions

• Disconnect power before installation/wiring/maintenance.

• Do not exceed maximum input voltage (60VDC).

• Ensure proper grounding to prevent electric shock.

• Operate within specified temperature range to avoid overheating.
