Before diving into the manual’s structure, it is essential to understand what the hardware does. The typical Ericsson PSU 4813 rectifier module converts AC mains (90–290V AC) or high-voltage DC to a regulated -48V DC (nominal) output. Here are the specs you will find detailed in Chapter 2 of the manual:
If you are integrating the PSU 4813 into a non-Ericsson system (e.g., Arduino or Raspberry Pi monitoring), the manual provides the exact frame format: 11-bit CAN ID, 8-byte data length.
Installing and configuring the Ericsson PSU 4813 requires careful attention to detail to ensure proper operation. Here are the step-by-step instructions for installation and configuration:
: The site grounding system must be tested and verified before power-up.
