Sel 735 Manual May 2026
If you don't have time to read the full 400-page manual, look for the Quick Start Guide (often included as a PDF on the shipped CD or available on the SEL website).
This condensed version is perfect for field technicians. It gives you the default IP address (usually 192.168.1.100 or similar), the default username/password, and the basic connection steps. Keep this printed out and taped to the inside of your metering cabinet—it will save you during a frantic commissioning session.
One of the reasons the SEL-735 is so popular is its ability to act as a Power Quality (PQ) monitor. The manual devotes a significant chunk of real estate to PQ Events.
