Installation Guide

Follow these steps to install the Yokogawa SPW482-53 correctly.

1. Power Down the System: Turn off all power to the Field Control Unit.

2. Locate the Slot: Find the designated power supply slot in the FCU or Node Unit.

3. Insert the Module: Slide the SPW482-53 into the slot until it seats properly.

4. Secure the Module: Fasten any retaining screws or latches.

5. Connect AC Power: Wire the Line (L+) and Neutral (N-) to the input terminals.

6. Connect Ground: Attach a grounding wire to the grounding terminal.

7. Apply Main Power: Turn on the 100-240V AC or 24V DC source.

8. Check Status LEDs: Verify the SYS and FLD LEDs both turn ON.

9. Measure Check Terminal: Use a voltmeter at the check terminal to confirm +5V and +24V.

10. Test Redundancy (if dual): For redundant systems, install a second SPW482 module.

11. Verify I/O Power: Confirm all I/O modules receive proper power.
