Installation guide for Rockwell Automation Compact I/O expansion power supplies, covering safety, assembly, mounting, wiring and specifications.
This guide provides step‑by‑step instructions for installing Rockwell Automation Compact I/O expansion power supplies (models 1769‑PA2, 1769‑PA2K, 1769‑PB2, 1769‑PB2K, 1769‑PA4, 1769‑PA4K, 1769‑PB4, 1769‑PB4K). It includes safety precautions, handling of electrostatic discharge, hazardous‑location requirements, and detailed procedures for assembling, mounting, connecting, wiring, and replacing fuses.
The document also lists the power‑supply components, specifies electrical ratings (voltage, current, isolation), and provides additional resources such as related Rockwell Automation publications and certification information.
| Input voltage range | 85–265 V AC |
|---|---|
| Input frequency range | 47–63 Hz |
| Isolation voltage | 265 V continuous (reinforced insulation) |
| Minimum enclosure IP rating for hazardous locations | IP54 |
No. The equipment does not support removal and insertion under power.
A minimum IP54 rating is required for UKEX/ATEX/IECEx Zone 2 certified enclosures.
