6. Installation & Maintenance
Installation
The module adopts a backplane design and needs to be inserted into a standard 140-series backplane. During installation, ensure stable backplane power supply (115/230 VAC) and follow modular installation specifications.
Maintenance
The working status can be quickly judged through the front-panel LED indicators (green for normal operation, red for errors). The module supports hot backup functionality, ensuring stable system operation even in the event of a single unit failure.
