Mechanical Data

‑ Weight: approx 1.6 kg ‑ Dimension: Series 90‑70 standard single‑slot module form‑factor

Main Functions

1. Converts 48 VDC field input into tightly‑regulated +5 V / +12 V / −12 V backplane power for all Series 90‑70 modules within the rack. Generates power‑fail sequencing signals so the CPU can execute orderly power‑down housekeeping tasks before DC bus collapse.
2. Optional dual‑rack power feeding reduces quantity of power supplies in multi‑rack system when total load permits.
3. Built‑in electronic protection prevents backplane damage caused by field short‑circuit or overload events.
4. Front‑panel LED indicators:   ‑ Green PWR OK: Power supply outputs within normal operating range   ‑ Red FAULT: Over‑voltage, over‑current, short‑circuit or input power failure condition

Installation & Wiring Requirements

1. Cut off 48 VDC field input power before installation or replacement. Hot‑swap is not permitted. Apply ESD protection during module handling.
2. Insert IC697PWR748D into the far‑left dedicated power‑supply slot of Series 90‑70 chassis and fasten module latch. If dual‑rack power feeding is required, connect IC697CBL700 cable between this unit and second rack.
3. Field 48 VDC input wiring comply with manual GFK‑1061D. Use appropriate wire gauge matched to input current; install external over‑current protection upstream of power‑supply terminals. Reliable protective‑ground connection for rack chassis is mandatory.
4. After replacement: Restore 48 VDC input power, observe front‑panel LED status. Measure backplane +5 V, ±12 V output voltages. Verify all CPU, communication and I/O modules boot and operate normally. For dual‑rack configuration, confirm load calculation is within 90 W total output limit.
5. Replacement note: Always calculate total rack power consumption before adding new modules to avoid overloading power‑supply unit. Full‑system commissioning test is mandatory before putting into service.
